Save Recipe – – PROCESS/RECIPE WIZARD

Archive – TOOLS > OPTIONS

To avoid collecting large amounts of data during a real-time profile run (which will then have to be saved as a single paqfile), Insight can periodically create intermediate archives during the run, with each archived paqfile containing a consecutive section of the run’s data. Data is collected in the archive paqfile for a specified length of time, at the end of which it is automatically saved and closed, and a new archive paqfile is automatically opened and data-collection starts afresh. This cycle of creating, saving and closing paqfiles continues until the user ends data-collection, and the archiving process then stops. The remaining data displayed on screen must then be saved as a paqfile by the operator.

Check Save Data Periodically to enable archiving, and set the time period to elapse between each save.

Archives are saved in the default paqfile directory. You may specify the filename prefix, and Insight adds to this the date and time of the file’s creation as part of its name.

Audit Trail – FILE > PROPERTIES

Summarizes key events in the history of the paqfile which may have affected the integrity of the data. Events are listed in the order in which they happened. The date/time of the event are shown unless not appropriate to the entry.

To view the audit trail, select File > Properties to open the Paqfile Properties dialog, and click Audit Trail.

An entry is added to the audit trail for the following events:

Creation of the paqfile by the merge paqfiles feature. If such a file forms part of a further merge, there is no additional audit trail entry: the creation of that new file starts a new audit trail.
Creation of the paqfile by data import.
Triggering of a Maximum/Minimum or Time at Temperature data analysis alarm during a real-time telemetry run, if the real time option is selected in the relevant Analysis Options dialog (or within a recipe or process file if one is applied). Thus, this shows that a red alarm screen has been acknowledged by the operator during a run.

The Paqfile Properties dialog is also available from the graph right-click menu.

To print the Audit Trail, select File > Print Options from the main menu.

Battery Life Q18 Logger

For a given battery type, battery life is affected by operating temperature, use of radio telemetry and sample interval; see your User Manual. Because of the great potential variability in operating conditions, values given here are no more than an indication of the battery life that can be expected. The best predictions can be obtained only by experience of the batteries’ use under the actual working conditions.

The data below applies only to batteries when used in the Q18 logger.

Calculate

Selects the region of the temperature profile over which the analysis is to be performed.

Over Current Zoom Displays and analyzes results for data contained within the area of the graph currently shown. Thus, if the graph has been zoomed, the analysis will be only for that horizontal region of the graph (i.e. measured along the time/distance axis) that has been selected for zoom. When no zoom is applied, the analysis will be for the temperature profile as a whole.
By Zone Displays and analyzes results for one oven zone at a time. The results for each oven zone are grouped together and displayed in the analysis table one after the other.
For a Specific Zone Displays and analyzes results for a single, specified oven zone.

Capability Statistics

See Statistical Process Control for use of the capability statistics.

Cpk and Ppk Cpk Ppk Cp Pp

In the past there has been considerable confusion on how to calculate Cpk. This was one of the reasons why Ppk was developed. The difference between Cpk and Ppk is the standard deviation value that is used.

Cpk uses the estimated standard deviation, which is calculated as follows:

where

is the mean range value.

Ppk uses the standard deviation calculated from the individual data:

Cpk is used to measure the potential capability of a system to meet customer needs. It should be used to analyze a system’s aptitude to perform. Ppk is used to measure the performance of a system to meet customer needs. It should be used to measure the systems actual performance.

In most cases, the process capability can be considered acceptable if the Cpk is greater than 1.00 and the Ppk is greater than 1.33.

Calculation of Cpk

Cpk is calculated using the following steps:

First, we determine the relationship between the process mean and the specification limits in units of standard deviations:

USL LSL

where:

is the process mean
is the estimated process standard deviation.

Note that this should be used rather than the actual standard deviation of the data (as shown in the Surveyor results); the actual standard deviation is used in the Ppk calculation rather than the Cpk calculation.

Once we have ZUSL and ZLSL, we select the minimum of these two values:

We can then calculate Cpk:

Cp and Pp Calculations

A common measure of Process Capability is in units of process standard deviations. The relationship between the process standard deviation and the range between the upper specification limit and lower specification limit is known as the Cp.

The formula for Cp is given below.

Note that an estimated standard deviation is used, as in the calculation of Cpk.

The formulae for Pp uses a standard deviation calculated from individual data. The formula for Pp is given below

Change Analysis – SPC > CHANGE ANALYSIS

When a Statistical Process Control file is open, it is possible to change the data analysis mode upon which the SPC is based.

From the Analysis Results list, select a different data analysis mode.

Selecting some analyses will require additional parameters to be entered here. Default values for these are taken from the first paqfile in the list but can be changed as necessary.

Click Next to go to the next stage.

The display of SPC results will show for the analysis calculation selected in the previous wizard stage the limits which are acceptable in your process. Enter here the target (ideal) value for the analysis calculation, and its upper and lower acceptable limits; two sets of limits (inner and outer) can be defined.

Ensure that the limits you specify are correct for your process; if this is not the case, the Capability calculations will be invalid.

Text in the dialog explains how the limits will be used in the Capability calculations.

Check Save these limits for next time to have the limits you set here become your default until they are changed again.

Click Finish to recalculate and display the results.

Change Files Used – SPC > CHANGE FILES USED

When a Statistical Process Control file is open, it is possible to change the paqfiles upon which the SPC is based.

Specify the paqfiles that you wish to include in the SPC. To list paqfiles from which you will make a choice, you can make Insight search for them according to criteria you set, or browse to specific files yourself.

Search for files, based on criteria you specify.

1. Specify the folder (and subfolders if required) to be searched. If you require Insight also to examine further folders, this can be done by a subsequent additional search (see below).
2. Specify criteria, e.g. date range, or within the last x days, etc. To include the last 10 paqfiles created, select Number = 10, Units = Files.
3. Click Advanced to select additional criteria which can further restrict the search to paqfiles associated with a given process or product.

- Select All Process Files and Products or specify a process or product by browsing to the appropriate process file or product file, in which case the file-search will be limited to paqfiles which use that process file or product file.
- You may select the use of Auto SPC, i.e. to Include future paqfiles which match search criteria. In this case, the SPC file which the wizard will create will, when opened subsequently, automatically select not only those files currently found by the criteria you are now specifying, but also any new files created subsequently which match the criteria. Running an analysis in future thus becomes quick and simple.
1. Click Search Now to start the search for paqfiles matching the criteria you have selected.

Browse to locate specific paqfiles. Use Shift and Ctrl to select multiple files at once. The dialog lists the contents of the default paqfile directory, though you can browse to any other location; the default directory can be changed.

Perform additional searches or browses as required; each time, the paqfiles chosen will be added to the Files Selected list. Click on the Name column-header to sort the files alphabetically (this does not change the SPC results, which are ordered by data-collection time of the paqfile).

To remove a paqfile from the list, select it and click Remove. To clear the whole list, click Remove All. Click Undo to reverse the last search or browse, i.e. to remove the last-found paqfiles from the list; searches or browses earlier than the last one cannot be undone.

The list must contain at least two paqfiles before SPC can proceed.

For SPC results to be meaningful, the paqfiles analyzed must be consistent, i.e. they must relate to the same process and must have used the same product with probes in same positions.

Click Finish to recalculate and display the results.

Copy to Clipboard – CLIPBOARD PASTE WIZARD

The Clipboard Paste Wizard guides you through the process of selecting data in a spreadsheet application and importing it to an existing or new paqfile. To start the wizard, select File > Utilities > Import from Clipboard.

The procedure is largely self-explanatory: enter information as prompted by the wizard, then click Next at the end of each stage.

In this first wizard stage, open your spreadsheet application, select the required range of temperature data, and copy it into the Windows clipboard.

To import data in the whole of an existing file which is in .TXT or .CSV format, select File > Utilities > Import from File.

Create or Merge – CLIPBOARD PASTE WIZARD

Choose whether the pasted measurements should be used to create a new paqfile or whether to merge them with an existing paqfile.

If being merged, specify whether to:

Merge with the current paqfile (the one currently displayed on screen), or
Load a new paqfile with which to merge the pasted measurements; browse to select the paqfile required.

If imported measurements are merged with an existing paqfile:

The new data is assigned to additional thermocouple numbers. For example, if merging with a paqfile with probes numbered 1 to 6, the imported probes would be numbered from 7 onwards.
The paqfile will have entries added to its audit trail to indicate that some of the probes were imported.
You may need to adjust probe alignment for the imported measurements if they do not correspond with the existing data’s time axis; select Process > Adjust Probe Alignment.

Paqfile Information – CLIPBOARD PASTE WIZARD

To make the data suitable for a paqfile, enter the sample interval and temperature units of the original data.

If you wish, add probe names, and date and time for the original data; use the date format dd/mm/yy or (if different) the short date format set in Windows (in Windows XP, see Control Panel > Regional and Language Options).

Paste – CLIPBOARD PASTE WIZARD

On clicking Paste, Insight interprets the contents of the Windows clipboard and displays the first few measurements.

If the data in the clipboard is not in the correct format, an error message will suggest what is wrong.

Close – FILE > CLOSE

Closes the currently open paqfile. If any changes have been made to the temperature profile data or to the process details since the file was last saved you will be prompted to save it or to close it without saving. If other paqfiles are also open, those files remain open.

You can also close a file by right-clicking the relevant tab at the top of the Graph Window.

Close All – FILE > CLOSE ALL

Closes all open paqfiles. If changes have been made to the temperature profile data or to the process details of any of the files since they were last saved you will be prompted to save them or to close them without saving.

Colors – TOOLS > OPTIONS

Select colors of your choice for alarm cells and non-alarm cells in the Analysis Window data grid. These can also be set with the Colors tab on any of the Analysis Options dialogs (click or select View > Analysis Options).

Communications Setup – LOGGER > SETUP

The data logger is connected to the PC by a USB port or a COM (serial) port, depending on the logger model. If the logger is being connected to a PC for the first time, it is necessary to enable communication between them, as follows. See also the dedicated User Manual for your logger.

If using connection by USB port, data may be gathered (via telemetry) from multiple loggers simultaneously.
If using connection by COM port, data may be gathered (with or without telemetry) from only a single logger during a given profile run.

For both hardwired and radio telemetry, connection of the logger to the PC can be by either USB port or COM port.
For radio telemetry, TM21 receivers connect to the PC via a USB port; older receivers connect by COM port.

Connection of the logger will normally happen automatically when the logger is plugged into the PC: connect the logger to a free USB or COM port and it will be ready to work. In case of any problems, note that the process should proceed as follows

Using the communications lead supplied, connect the logger to a free USB port or COM (serial) port on the PC (if using multiple loggers, you must use USB).

To minimize communications problems, connect the lead first to the PC and then to the logger.

The red LED on the logger should flash five times to confirm that the connection between the communications lead and the logger has been made.
If using a USB port, and if the PC is having a Datapaq logger connected for the first time, Windows will display a Found New Hardware message and the PC is then ready to work with the logger. If any warnings are displayed about driver-signing, confirm them (Datapaq drivers have been tested, and were installed when Insight was installed).

Typical sources of problems with establishing communication:

Communications lead not fully inserted Check correct sockets are being used.
Damaged communications lead or connectors Check for breaks and other damage. Replace the lead.
Wrong COM port selected (if connecting by COM port) Follow the procedure below to select the correct port.
Battery not charged (if using rechargeable battery) Recharge the battery, ensuring the charging LEDs are illuminated.

Select Logger > Setup to open the Communications Setup dialog.

In order to view the Communications Setup dialog when multiple loggers are to be used, each logger must be attached to the PC separately.

If necessary, select the connection type used: USB port or COM (serial) port (and, for a COM port, the port number). Alternatively, click Detect to auto-detect the port in use.
Click Test.

If the logger is detected, its type and the port to which it is connected are displayed.

Shortcut -Pressing F4 on the keyboard opens the Communications Setup dialog, looks for the port currently in use, and displays the port and logger type (equivalent to clicking Detect in the dialog).

For more information on the logger in use, click the Diagnostic button which now appears. Additional data shown covers firmware version, maximum permitted internal logger temperature, battery charge status, serial number and temperature recording range. Current temperature of the probes (updated every 5 seconds) is also shown or open circuit (*OC*) if no probe is attached; the temperature of the thermocouple cold junction is effectively the current internal temperature of the logger.

Probe temperatures, and the logger’s internal temperature, are also shown in the logger Reset dialog.

Contour Plot – VIEW > CONTOUR PLOT

For conveyorized oven types only.

Opens the Contour Plot window, which shows a diagrammatic view of the product as seen from above, color-coded to show temperature contours, and with controls to show the profile’s heating/cooling sequence as an animation. Probe positions are marked.

The diagram is color-coded according to a temperature scale whose color palette can be adjusted to provide the best display for a given temperature range. To achieve smooth temperature contouring, Insight performs linear interpolation between actual measured temperatures.

Re-size the product picture as you wish by dragging on the window’s edges or by maximizing it.

You can turn probes on and off by clicking on the probe number in the Analysis Window data grid. This removes the probe from the contour plot, and removes the probe’s data from the graph and from the data grid; its data are then also removed from the analysis calculations.

When View Data analysis mode is selected, you may move the display through the data by:

Dragging the cursor across the graph, or
Scrolling the data grid, or
Dragging the slider in the Contour Plot window.

Or use the controls in the Contour Plot window to animate the display.

Copy to Clipboard – EDIT > COPY

The Copy to Clipboard dialog is also available from the graph right-click menu.

Copy to Clipboard allows you to export your temperature profile data, analysis results or graph in order to use them in other applications. Select which type of data to export, and the format you wish to use. The information is then placed on the Windows clipboard and can be pasted into (e.g.) a word processor, spreadsheet or bitmap-editing application.

Trend Data Points -(For SPC file only.) Export the data points in the Statistical Process Control graph.

Analysis Results -Export the data analysis performed on the collected data. Everything contained in the analysis grid at the time of export is included, thus:

Select the analysis mode you wish to export before opening the Copy to Clipboard dialog.
If the graph is zoomed, the data on which the analysis is performed is correspondingly limited, and these are the results that will be exported.
Select As Image to export a bitmap image of the analysis grid.
Choose whether or not to include a file header with the exported data. This provides additional information such as logger identification, probe names, collection start time, etc.
Choose multiple analyses and click ‘Select’ to choose which analyses (or all) to export simultaneously.

Raw Measurements -(For paqfile only.) Export the raw temperature/time data as gathered by the logger. All the profile’s raw data are exported, regardless of the how the graph is zoomed.

Under Export Every, select the proportion of the raw data to export. Thus enter 1 to export every data point or (e.g.) 5 to export every fifth one.
Choose whether or not to include a file header with the exported data; this is necessary if you may later want to re-import the data into Insight.
Data can be exported with file header in the format used by earlier Datapaq software (.EXP). This allows the data to be imported into Datapaq Tracker version 4.
If the graph has been zoomed, choose whether to export only the data included in the current zoom view, rather than the whole paqfile.

Graph -Export a bitmap image of the graph.

Text -Export data as simple text.

CSV -Export data in Comma Separated Value format useful for pasting into spreadsheet applications (NB This format will not paste into Microsoft Word or into most text editors).

Export to File -Exports to a file instead of to the clipboard. Default location for the file is the paqfile directory, though you can browse to specify a different filename and/or location.

To obtain a quick hard-copy version of the analysis results or raw data (as well as of the graph and other information) you may produce a printed report (set options with File > Print Options, and then Print).

Thermocouple Correction Factors

For maximum accuracy when running a temperature profile, it is essential that the thermocouples used have been accurately calibrated, and that correction factors are established so that they can be applied to the data.

If correction factors are known for the whole range of operating temperatures, and if a linear relationship is assumed between adjacent temperature set points, corrections can be applied to all data within the calibrated temperature range. Insight stores these correction factors in a correction factor file, and correction is achieved by applying this file to the data. Correction factors will be applied to the whole of the data which lies within the calibrated temperature range.

The use of correction factors must be enabled to make the Correction Factors menu and other relevant options visible.

Insight stores correction factor files by default in the default paqfile directory.

A paqfile cannot have more than one set of thermocouple correction factors applied to it, nor can the same factors be reapplied successively, e.g. if a measurement was corrected from 202 to 200 C by applying thermocouple correction factors, it is not possible to apply the factors again to obtain 198 C.

To safeguard against falsification of data, the application, removal and editing of correction factors is recorded in the audit trail.

Thermocouple wire is often supplied to the end user on spools, and the supplier calibrates (in a temperature-controlled bath) a thermocouple made from a sample of wire from the spool. Measurements thus taken indicate how far the thermocouple’s readings deviate from a range of known set temperatures: e.g. at a true 200 C the thermocouple may read 201.7 C, and this thermocouple correction factor (also known as a calibration offset) of 1.7 C can be applied to thermocouple readings taken at this temperature. In practice, to allow for variation within the spool, correction factors are measured for samples from the start and end of the spool and these are averaged to give a final correction factor value for a given temperature set point.

Thermocouple correction factor files have a .CAL extension.

Creating a Thermocouple Correction Factor File

Use the Thermocouple Correction Factor Wizard. To run the wizard, select:

File > New > Thermocouple Correction Factors, or
Correction Factors > Setup Thermocouple Correction Factors.

This takes you through the necessary steps one after the other.

You may create a thermocouple correction factor file which contains data for more thermocouples than are supported by the logger to which it will be applied. Data for any thermocouple numbers in excess of those supported by the logger will be ignored by that logger.

Editing an Existing Thermocouple Correction Factor File

Select File > Open > Thermocouple Correction Factors. This opens the selected thermocouple correction factor file for editing in a modified version of the Thermocouple Correction Factor Wizard.

Printing Thermocouple Correction Factor Data

To print the data in a thermocouple correction factor file, edit the file as above and click ‘Print’ in the main editing dialog.

Applying Thermocouple Correction Factors

Thermocouple correction factors are most easily applied to temperature profile data as an automatic part of the logger download operation; to enable this facility, select Tools > Options > Logger. To apply correction factors subsequently (or to any paqfile), select Correction Factors > Apply Thermocouple Correction Factors.

When running a profile using hard-wired telemetry or radio telemetry, a correction factor file can be applied immediately after resetting the logger, so that the temperature profile can be watched developing with the corrected data; enable this facility as above.

Removing Thermocouple Correction Factors

Select Correction Factors > Remove Thermocouple Correction Factors to remove the effect of the thermocouple correction factors from the currently displayed paqfile. The graph and analysis data on screen are updated accordingly.

Creating a Process File

A process file can be created using either of the following.

Process Details dialog Click , or select Process > Process Details, or (to adapt an existing process file) File > Open > Process. Enter data into the dialog and then use the Save As option on the Overview tab of that dialog.
Process Setup Wizard Click , or select Tools > Wizards, or File > New > Process. You will be guided step by step through the process of entering the necessary data.

As part of using the Process Setup Wizard, the component oven, recipe and product files will also be created. In creating a process file by using the Process Details dialog you can choose either to do this or to save only the process file as a whole.

In each case:

Existing oven, recipe and product files can be used to form the components of the process, or
Fresh data can be entered directly, or
These approaches can be combined.

Similarly, oven, recipe and product files can each be created using either:

The Process Details dialog, or
Their own wizards.

When a process, recipe or product file is created it will be suitable for a data logger with the same number of probes as the currently set default (which will normally be the same as your last-used logger). To create a process, recipe or product file for use with a logger having a different number of probes, enter the new number of probes on the Logger tab of the Global Options dialog (select Tools > Global Options) and then create the file.

File Extensions and File Locations

See information on directories for a description of the locations in which the different file-types are stored and the file extensions used for each.

Editing Existing Files

To edit an existing process, oven, recipe or product file, you may also open it first by selecting File > Open > Process/Oven/Recipe/Product to open a modified version of the Process Details dialog. Make changes as necessary and then use the Save As button to save a new, modified copy of the file.

By using the Process Details dialog, existing process, oven, recipe or product files can be used as a basis and their data edited either to create an entirely new process file or to create adapted process, oven, recipe or product files. This cannot be done using the wizards: in that case, all the data for an oven or recipe or product file must be entered afresh.

Creating and Using Tolerance Curves

What is a Tolerance Curve?

A tolerance curve provides an envelope of acceptability against which to compare the temperature profile from a product’s run through the oven. The curve can have inner and outer bands of acceptability. When the tolerance curve is overlaid on the temperature profile, a visual comparison can be made to assess whether the results are acceptable, and, if not, alarms can be triggered.

Creating a Tolerance Curve

A tolerance curve can be created from an existing temperature profile (paqfile) whether currently displayed on screen or whether held on disk or it can be drawn freehand, or created from imported data in a .CSV (spreadsheet) or text file. This is done with the Tolerance Curve Wizard (click or select Tools > Wizards or File > New > Tolerance Curve).

Tolerance curves have a .TOL file extension. There is a default directory in which they are stored, although this can be changed.

Editing a Tolerance Curve

To edit an existing tolerance curve, select File > Open > Tolerance Curve, or access the editor from the Recipe – Tolerances tab of the Process Details dialog (click or select Process > Process Details). From here you may also export the tolerance curve data to the clipboard and edit it, e.g. in a spreadsheet application, before creating a new tolerance curve with it.

You may also edit tolerance curves which are already applied to a paqfile by selecting Edit Tolerance Curves from the Process menu or from the graph right-click menu. NB Editing in this way will affect only the tolerance curve associated with the paqfile it will not change the tolerance curve file itself.

Applying a Tolerance Curve

The easiest way to apply a tolerance curve to a paqfile is to incorporate it in a process file which is applied to the data when downloading from the logger.

To apply a tolerance curve to an existing paqfile, use one of the following:

Process Details dialog (click or select Process > Process Details). Here, to apply a single tolerance curve, you may select a curve directly, or apply a process or recipe file which incorporates use of a tolerance curve.
Overlay dialog (on graph right-click menu, or select View > Overlay). Here, you may select up to four tolerance curves and choose which of these will be displayed on the graph at any one time.

Use the Graph Options dialog to choose colors for the tolerance curves and whether or not to display the inner and/or outer bands and the curve’s initial profile.

Alarms for Out-of-tolerance Data

You can choose whether or not to show an alarm if there are out-of-tolerance data in the temperature profile. Select this option on the Recipe – Tolerances tab of the Process Details dialog (click or select Process > Process Details).

Alarm Notification –When triggered by data from one or more probes falling outside the tolerance curve an alarm is shown in two ways:

At the bottom of the Analysis Window, an additional Alarms tab appears, giving detailed information on the alarm triggered; this tab also appears when analysis alarms (analysis results falling outside specified limits) or run alarms (events during the profile run) are triggered.
Alarm Status traffic lights in the Graph Window turn red and the printed report shows in the top right corner (this is also caused by analysis alarms and run alarms).

If there are inner and outer tolerance bands in the curve, alarms are not affected by the inner band: only data points falling beyond the outer band trigger an alarm.

Data Analysis Overview

The Analysis Window, below the graph, shows the numeric values calculated for each probe’s data using one of several possible analysis modes:

Reflow Results	Temperature and time data specific to the reflow process.
Wave Solder	Temperature and time data specific to use of the wave solder process.
Maximum/Minimum	Maximum and minimum temperatures, with related statistical data.
Time at Temperature	Time taken to reach user-selected temperatures and the time spent above or below each of these.
Rise and Fall Times	Rates of heating and cooling over given temperature ranges, and the time the temperature is within each range.
Slopes	Maximum rates of heating and cooling, the times at which these occurred, and average rate of change of temperature.
Peak Difference	Data for the two probes which recorded temperatures with the biggest difference at any single point in the profile.
View Data	Raw time, distance and temperature data for each probe.

Use the tabs at the bottom of the Analysis Window to switch between different analysis modes.

Use Statistical Process Control to identify trends in the analysis results over time, and thus identify potential problems in your process before they occur.

Use virtual probes to display an average of some or all the probe traces and to show how the slope of a curve changes.

Display and Analysis Options

The Analysis Window is separated from the Graph Window by a movable splitter bar. Click on it and drag to change the proportion of the screen occupied by each window.

Depending on the analysis mode and on other options selected, the following control buttons are available to configure the display of data:

Analysis Options		Displays the Analysis Options dialog for the analysis mode currently being viewed. Use this to select the information you wish to be displayed and to configure alarms (see below).
Edit Probe Names		Assign and edit a name for each numbered probe.
Switch Grid Orientation		Switches the orientation of tabulated data, i.e. toggles between displays with the probes listed along the side or along the top of the analysis grid.
Change Sort Order		When multiple files are overlaid on the graph, or when the paqfile contains data from multiple loggers, this control switches the way data from probes are grouped in the analysis grid: clicking causes the results for each probe to be listed by file or by logger (all data for each file or for each logger are together), groups them by probe number (all data for each probe number are together).
Show/hide disabled probes		View Data analysis mode only -When the view of some probes is disabled (see below), you may click to hide the data columns for those probes. Click to show those empty data columns again.

Zooming

Any region of the graph can be zoomed by dragging out a rectangle (from top left to bottom right) over the selected area. If Calculate Over Current Zoom has been selected in Analysis Options, the data shown in the Analysis Window then apply only to the region of the graph (measured along the time/distance axis) that has been selected for zoom, and calculated figures are derived only from that section of the data.

Return to normal view and restore the full data analysis by double-clicking on the graph. Other zoom options are available.

Turning Probes On and Off

In the Analysis Window data grid, click on a probe number to remove its data from the graph and from the data grid; the data are then also removed from the analysis calculations. Click on the number again to restore its data. Right-clicking on a probe number removes all probes except that one from the graph and from the analysis; right-click on the number again to restore the other probes.

Probes can also be turned on and off by clicking buttons on the probe toolbar (if it is not displayed, select View > Probe Toolbar on the main menu).

Probes names are shown in the Probe Key to the right of the graph, and also appear when the cursor is held briefly over the probe number on the analysis data grid.

To assign or change probe names, use the Edit Probe Names dialog (click in the Analysis Window or select Edit > Probe Names) or the Product tab of the Process Details dialog (click on the main toolbar, or select Process > Process Details).

See also use of the logger toolbar (only when using multiple loggers).

Alarms

For most analysis modes, temperature profile data which are outside specified limits or values can be highlighted automatically. Use the Analysis Options dialog to specify such values. For more information on setting alarms, refer to Analysis Alarms. (You may also set alarms to be used with tolerance curves.)

If an alarm is triggered, an additional Alarms tab appears at the bottom of the Analysis Window. This tab gives detailed information on the alarm triggered.

Display Problems

If the following message appears when trying to open any window that should display a PCB in 3D mode, the program is having a problem with the OpenGL interface to your computer’s display. This is most likely on systems with 3D accelerated display hardware, particularly under Windows Millennium Edition.

If this occurs, make sure you have the latest available version of display driver for your hardware (usually available for free download from manufacturers’ web sites).

Adjust Oven Start – – LOGGER DOWNLOAD WIZARD

It is valuable to define precisely the oven start position in the temperature data in order that different paqfiles (i.e. data from different temperature profile runs) can be compared with each other. Click Yes to open the Adjust Oven Start dialog.

Click No to continue the wizard without adjusting the oven start.

If you have applied a process file which specified that the oven start position be adjusted, you will not need to use the Adjust Oven Start dialog unless you wish to adjust it by eye.

If you do not wish to adjust the oven start at this point, you can still use the Adjust Oven Start dialog at any time subsequently.

Download from Logger – – LOGGER DOWNLOAD WIZARD

The Logger Download Wizard guides you through the process of transferring to the PC the data you have collected during a profile run.

You can also perform a simple download of the logger by clicking on the toolbar or by selecting Logger > Download).

For a complete description of running a temperature profile using the Logger Reset and Download dialogs, see Running a Profile.

Start by using the communications lead supplied to connect the data logger to a free USB or COM (serial) port on the PC (to minimize communications problems, connect the lead first to the PC and then to the logger). The red LED on the logger should flash five times to confirm that the cable logger connection has been made.

The procedure is largely self-explanatory: enter information as prompted by the wizard, then click Next at the end of each stage.

Download Completed – – LOGGER DOWNLOAD WIZARD

The temperature profile data from your run have now been downloaded from the logger to the PC. Disconnecting the communications lead will preserve the charge in the logger’s battery.

You can set alarms to be triggered during a logger download, to warn you of incomplete or invalid data recorded during the profile run.

Print Paqfile – – LOGGER DOWNLOAD WIZARD

Select whether or not to print the downloaded temperature profile data.

Click Yes to print the paqfile. A full report (graph and analysis results) is printed on the current printer. The report’s contents follow the currently set print options; select File > Print Options to change these. You will then exit the wizard.

Click No to exit the wizard without printing.

Save Paqfile – – LOGGER DOWNLOAD WIZARD

Select whether or not to save the downloaded temperature profile data as a paqfile. This will allow you to view and analyze the data at any time in the future. If a process file was applied earlier in the wizard, the process information will be saved as part of the paqfile.

If you select Yes, the directory in which the paqfile is to be saved will be shown. This is the default directory in which paqfiles are stored, but you can browse to a directory of your choice. The browse option can be disabled if preferred: select Tools > Options > Paqfile Directories and check Fix Paqfile Directory.

You can enter a filename of your choice, but a default name will be suggested. If you have applied a process file, the name of the process will be used as a prefix for the paqfile’s name. The remainder of the filename will be the date and time that the logger started the data-collection run, in the form yyyy-mm-dd hh-mm . Thus, for a process called Process One’, the filename would be such as:

Process One 2003-07-29 15-14.paq

Click No to continue the wizard without saving the data.

The data will remain on screen after the wizard closes, and you may save it subsequently if you wish.

Select Process File – – LOGGER DOWNLOAD WIZARD

You may choose a process file to apply to the results. Click Use No Process File if you do not want to apply a process file.

The list of files shown for selection are those contained in the default process file directory, but you can also click Browse to locate files which you may have stored elsewhere.

If you do not wish to apply a process file at this point, you can still apply one subsequently.

v.7.2

Datapaq Insight Software is a comprehensive and feature-packed analytical tool which makes everything from routine quality checks to complex investigations easy meaning more time on task and much less working out how to do it.

To help you get the information you need from your temperature profiles, Datapaq Insight Software makes extensive use of wizards. These lead you step-by-step through all the major functions of the software from resetting a data logger to building a process file. At each stage of a wizard, comprehensive Help is available. Using the wizards is the best way of ensuring you are getting the most from your software.

Simply . . .

Click on the toolbar, or
Select Tools > Wizards from the menu, or
Right-click on the graph with your mouse to bring up the shortcut menu.

Invalid Data and Other Data Markers

The various types of data marker which may be contained in a temperature profile are shown in the View Data grid as follows. All represent invalid data except as indicated.

OC	Open circuit.
NA	Data not available.
LO	Temperature measured was below the range of the logger.
HI	Temperature measured was above the range of the logger.
BZ	Data marker introduced by Hall-effect switch (not showing invalid data).
***	Calculation cannot be performed (not necessarily because the data are invalid). Does not appear in View Data analysis mode.

Typical causes of invalid or interrupted data are:

Start or stop trigger at the oven entrance or exit did not work.
Thermocouple becoming detached from the logger.
Faulty connection.

Checking Hall-effect Switch

Ensure that the triggering magnets for the Hall-effect switch pass close to, and parallel with, the sensor.
Check that the yellow logger LEDs flash when the sensor passes the magnets.

Be careful that, in the course of checking, the logger does not pass through the oven unprotected by its thermal barrier.

Other Faults

A methodical approach is required to trace problems. In particular, make a careful visual check of thermocouples and connections.

Logger Communications Problems

Typical sources of problems with establishing communication:

Communications lead not fully inserted -Check correct sockets are being used.
Wrong COM port selected (if not using USB) -Follow the standard procedure to select the correct port.
Battery not charged -Recharge the battery, ensuring the charging LEDs are illuminated.
Damaged communications lead or connectors –Check for breaks and other damage. Replace cable.

Logger Download – – LOGGER > DOWNLOAD

Select Logger > Download to transfer to the PC the data you have collected during a profile run.

Start the download process directly by clicking on the toolbar or by pressing function key F3.

You can also download the logger using the Logger Download Wizard (click or select Tools > Wizards).

For a complete description of running a temperature profile using the Logger Reset and Download dialogs, see Running a Profile.

If you will normally not wish to apply a process file to the results, you can opt not to have the Select Process dialog displayed immediately after a download (a process file may then still be applied subsequently).

If enabled, the Apply Correction Factors dialog then appears in order that you may choose thermocouple correction factors to apply to the results.

Selecting a correction factor file from the lists will display the spool or batch numbers of the thermocouples.

If you will normally not wish to apply thermocouple correction factors to the results, you can opt not to have the Apply Correction Factors dialog displayed immediately after a download (a correction factor file may then still be applied subsequently).

During hardwired telemetry, Insight can apply correction factors to data as it is received, so that the real-time data display is accurate.

The newly downloaded data then appear on screen as a paqfile and can be displayed, analyzed and printed as you wish.

You can set alarms to be triggered during a logger download, to warn you of incomplete or invalid data recorded during the profile run.

Information about the logger and the data-collection process for the paqfile (including time/date, trigger mode and maximum internal logger temperature) can be seen in the Paqfile Properties dialog (select File > Properties, or graph right-click menu).

Logger – TOOLS > OPTIONS

Default Number of Probes -Specify the number of probes available on your logger. The default setting is six, though the number appearing here changes to reflect the number of probes available on the logger that was last used. To create a process, recipe or product file for use with a logger having a different number of probes from that normally used, enter the new number of probes here and then create the file.

Further information on the last-used data logger is provided here for information only:

Last Logger Used -Model of logger used during the last download or reset.

Last Logger ID -Identification number of the logger with which Insight last communicated, i.e. the one used during the last download or reset, or during communications setup. The logger’s 4-digit numerical ID (serial number) is on the rear of the logger and is also stored internally.

Advanced -Click for further options:

Enable a warning and/or disable reset if the logger is too hot (not available for all logger types).
Download the profile of the logger’s internal temperature for each profile run: this appears in the Graph and Analysis Windows as if it is data from an additional probe (not available for all logger types). To enable/disable display of the data when the resultant paqfile is open, select File > Properties > Advanced.
If a temperature trigger is used to start data-logging, the logger also records data before this point is reached. You can choose to download this pre-trigger data as part of the temperature profile; it will fall before the zero time point.
You may set a default sample interval, and it is then not possible to edit that value in the Logger Reset dialog. If the default value which is set is lower than is permitted for the logger involved, the value will be increased to that logger’s minimum, and the increased value will be shown in the Logger Reset dialog when the logger is reset.
Select the frequency of the local electricity supply (50 or 60 Hz).

Prompt for correction factors when downloading -You may select to be prompted to apply thermocouple correction factors when downloading data (disabled by default).

Logger Listen Mode – LOGGER > LOGGER LISTEN MODE

If, while a telemetry run is in progress, you stop receiving transmitted data for any reason either because you have selected Stop Real Time Mode, because you have exited Insight, or because of a system crash you may select Logger Listen Mode to resume the collection of transmitted data.

After the first few data packets have been received, the data starts to be displayed in the Graph and Analysis Windows.

While a radio-telemetry run is in progress, you may use the Real Time Tool dialog to check the integrity of data-packets as they are received, as well as the status of the logger(s) and (if using the TM21 radio-telemetry system) the receiver(s) (click

on the toolbar, or select View > Real Time Tool).

Logger Reset – – LOGGER > RESET

The Logger Reset dialog readies the logger to receive fresh data before a new profile run.

Any data stored in the logger but not yet analyzed must be downloaded before proceeding, as resetting the logger will permanently erase all data stored in it.

If using a single logger for a profile run, you can also reset the logger using the Logger Reset Wizard (click or select Tools > Wizards).

For a complete description of running a temperature profile using the Logger Reset and Download dialogs, see Running a Profile.

If using telemetry and any Datapaq loggers which communicate via USB, data may be gathered from multiple loggers simultaneously. Each logger is reset separately in turn, as if resetting a single logger as described here.

Start by using the communications lead supplied to connect the logger to a free USB or COM (serial) port on the PC (if using multiple loggers, you must use USB).

To minimize communications problems: a) connect the lead first to the PC and then to the logger; b) if using USB, always use the same USB port the one which was first used to set up communications.

The red LED on the logger should flash five times to confirm that the connection between the communications lead and the logger has been made.

Open the Logger Reset dialog select Logger > Reset, or click on the toolbar, or press function key F2 and choose options as necessary.

Sample Interval

Set the time which is to elapse between each set (sample) of data points (one data point for each probe) that the logger will collect. This sample interval is normally selected to ensure that 800 1,000 samples are stored over the whole run. Thus, sample interval is the profile duration in seconds divided by the number of samples required. The shorter the sample interval the better you will be able to record short-term variations in your temperature regime but the total recording time available to you will be reduced, and the data will take longer to download to the PC after the run. Restrictions apply to the sample intervals allowed, depending on:

Logger type.
Type of telemetry used, if any.
Use of humidity sensor.

You may set a default sample interval, and it is then not possible to edit that value in the Logger Reset dialog. If the default value which is set is lower than is permitted for the logger involved, the value will be increased to that logger’s minimum, and the increased value will be shown in the Logger Reset dialog when the logger is reset.

Probes Selected

To conserve memory in the logger, click on the relevant buttons to deselect those probes which will not be used. The number of probes available and the logger memory size are dependent on the logger used (see the dedicated User Manual for your logger). If using the XDL12 logger, the thermocouple type of each probe and its socket color are shown.

Probe 1 must always be one of those selected.

You can also use the Edit Probe Names dialog (click in the Analysis Window or select Edit > Probe Names) or the Product tab of the Process Details dialog (click or select Process > Process Details).

Mode (Tpaq21 logger only)

Click ‘Advanced’ to set up multiple events, i.e. to have different sample intervals and trigger modes for different stages of the profile run.

Two events are enabled by default. Click ‘Add’ to define an additional event. To remove an event which has been set up, select the event number and click ‘Remove’; subsequent events are then renumbered.

For event 1 any trigger mode can be selected; the data transfer (telemetry) mode (which will apply for the whole of the profile run) must also be chosen while event 1 is selected.
For event 2 onwards the only trigger modes which can be selected are rising temperature and falling temperature; select also the sample interval required for each event; data transfer selection is disabled.

For event 2 onwards, the minimum sample interval for use with telemetry is 1 s. If the interval is set lower than 1 s, the logger will stop transmitting when it reaches that event (a warning that this will happen is shown in the Data Transfer section of the dialog).

Settings made for probe selection apply to all events, regardless of the event that is currently selected in the dialog.

The maximum possible duration of a run with multiple events cannot be predicted, so the memory calculator (see below) is not available.

Multiple events cannot be set up by using the Reset Wizard.

Data Transfer

If your system supports telemetry, you will be able to select whether to use no telemetry, or to use hardwired telemetry (serial telemetry) or radio telemetry to transmit data from the logger to your PC.

If using the TM21 radio-telemetry system, you may click Advanced Telemetry for the following options.

Transmissions -The system’s transmitter can make multiple transmissions (‘interleaving’), i.e. it sends each reading a number of times in order to increase reception quality. This can overcome momentary interference such as that caused by the switching of large electrical loads, but it consumes more power and so will shorten the logger battery’s operation time; it should thus be used with caution. Typically, three transmissions is a good compromise for most industrial processes. Using interleaving increases the minimum sample interval which can be achieved.
Transmit Frequency -The frequency to which the currently-connected receivers are set is shown for information. On opening the dialog, the same value is shown for transmitter frequency (regardless of the transmitter’s current setting), as you will normally want transmitter and receivers set to the same frequency. However, if you wish to change the transmitter frequency, you may do so here: click the up or down arrows to select one of the available frequencies. If the currently-connected receivers and transmitter use incompatible frequency bands (e.g. because they are specified for different regions of the world), the receiver frequency is shown in red. (If no powered-up receiver is connected to the PC, the transmitter frequency shown on opening the dialog will be that which the transmitter was previously set to.) On clicking ‘OK’ in the Logger Reset dialog, the transmitter frequency will be set to the value shown in the Advanced Telemetry dialog; in normal use, this will be the same value as the current receiver frequency.

To adjust the system’s frequency, for most purposes it is better instead of using the Advanced Telemetry dialog to first set the receiver frequency using the Radio Frequency Wizard (select View > Radio Receivers): this will search for suitable frequencies and rank them according to their susceptibility to external interference and, once a receiver frequency is chosen, Insight then automatically sets the transmitter to the same frequency when the logger is reset. (For setting frequency in older radio-telemetry systems, see your hardware manual.)

Memory Calculator

Calculates the maximum time for which the logger can collect data, given the sample interval, the number of probes and the logger’s memory size. The time available may be further limited by the level of battery charge.

Battery Status

The charge indicator gives both the current percentage of full charge held by the logger battery, and a color-coded report:

	Sufficient charge to perform a run.
	May be enough charge for a run, but battery getting low.
	Insufficient battery charge: recharge immediately.

Rechargeable nickel-metal-hydride batteries discharge slowly even when not in use and will need charging if left for more than three weeks. With the Q4, Q6, Q18, Datapaq 9000, XL2 and XDL12 loggers a full charge can be completed in two hours; with the XL logger a full charge will take one hour using the computer interface or 14 hours using the ChargePaq or MemoryPaq charger; with the MultiPaq21 and Tpaq21 loggers a full charge takes 2 3 hours.

The battery charge level will not be displayed if the logger is on charge: disconnect the charger to verify battery status.

The display is invalid for lithium batteries.

If in any doubt, abort the procedure by clicking Cancel, and recharge the logger.

Battery life data is available for the Tpaq21 logger.

Trigger Mode

Select here a means to start the logger recording data.

No Trigger -Data recording starts immediately the reset is complete and the communications lead has been disconnected from the logger (not available for all logger types).
Start Button -After reset, data recording starts when the logger’s green start button is pressed and held for about 1 second.
Date and Time -Data recording starts at a specified date and time. The current date appears by default.
Rising Temperature -Data recording starts when the temperature of any probe (probe no. 1 with MultiPaq21 logger only) rises to the specified value. (If rising or falling temperature trigger mode is set, the logger records data from the time it is disconnected from the PC but, once the trigger temperature has been reached, the logger keeps only a maximum of 60 data points before the trigger point and discards any others. NB Tpaq6 and Tpaq21 loggers do not store this pre-trigger data.)
Falling Temperature -Data recording starts when the temperature of any probe (probe no. 1 with MultiPaq21 logger only) reaches the specified value as it is falling.

Probe Temperatures

The current temperature measured on each of the logger’s channels is shown, updated every 5 seconds. This serves as a useful check that thermocouples are working properly. (This feature is not supported by some loggers.)

Logger Temperature

The current internal temperature of the logger is shown. (Only for Q18 logger and, if Transducer Interface is attached, XL2 logger.)

Probe temperatures, and the logger’s internal temperature, are also shown in the Communications Setup dialog.

After clicking OK, the logger is reset and a message box confirms the sample interval and trigger mode you have set.

If you have selected:

No Telemetry
Disconnect the communications lead; the logger’s red and green status LEDs then briefly flash alternately to confirm logger reset.

Hardwired (Serial) Telemetry
Leave the communications lead connected, and click OK.

Radio Telemetry
Ensure the (primary) receiver is connected to the PC via a USB port, and to its power supply. Then disconnect the communications lead from the logger. The logger’s red and green status LEDs then briefly flash alternately to confirm logger reset; click OK.

If using telemetry:

The Select Process dialog then appears in order that you may choose a process file to apply to the results. If the process file and its components have been given names, these are shown when the process file is selected in the list. Click No Process if you do not want to apply a process file. A process file allows you to see the temperature profile in relation to the furnace zones as the profile appears on screen during the run.

If enabled, the Apply Correction Factors dialog then appears in order that you may choose a thermocouple correction factor file to apply to the results. Click No Factor if you do not want to apply a correction factor file.

If you will be gathering data (via telemetry) from multiple loggers simultaneously, you may now reset further loggers by the same process. The same process file (or no process file), as selected above, will be applied automatically to each of the loggers.

Logger LEDs: how to interpret the logger’s status lights

Logger Toolbar – VIEW > LOGGER TOOLBAR

Displays or hides the floating logger toolbar when multiple loggers are used during a profile run using telemetry, or when viewing a paqfile containing data from multiple loggers.

For each logger is shown logger number (used to identify the probes from each logger in the Analysis Window, the probe toolbar and the probe key to the right of the graph), logger type and serial number.

Click on individual logger buttons to turn data from those loggers on and off, i.e. to remove their data from the graph and from the data grid; the data is then also removed from the calculations in the analysis data grid. Click on a logger button again to restore its data. Right-clicking on a logger button removes all loggers except that one from the graph and from the analysis; right-click on the button again to restore the other loggers.

Click to the right of the logger button for further options:

Discard Data Permanently removes that logger’s data from the graph and the analysis. If telemetry is in progress, any subsequent data received from that logger during the current profile run will be ignored.
Stop Data Collection When telemetry is in progress, any subsequent data received from that logger will be ignored. Data already collected is retained.
Save Paqfile Saves, as a separate paqfile, the data from that logger only.

Maximum/Minimum – – VIEW > ANALYSIS OPTIONS

This analysis mode displays maximum and minimum recorded temperatures, with related statistical data.

To print the analysis results, select File > Print Options from the main menu.

To select the data you wish to display, and the alarm criteria, click (or select View > Analysis Options) to display the Analysis Options dialog.

Display Options

Select here which results will be displayed in the Analysis Window. The results are listed in the grid for each probe separately – though you may turn probes off if you choose. Each of the options can be applied to the whole profile or to only a specific part of it (see ‘Calculate’, below).

Maximum Temperature -Highest temperature reading from a given probe. Useful for indicating when the product reaches too high a temperature.
Time Reached Maximum -The time after the start of the profile run at which a given probe’s maximum temperature was recorded.
Mean Temperature -Mean of all temperature readings for a given probe during all or part of the profile run.
Deviation from Set Temperature -Greatest deviation from a set temperature recorded at a given probe. The value reported is the difference between the maximum value recorded (within the region of the data being analyzed) and the set temperature; the value reported is thus negative if the maximum temperature is less than the set temperature (NB that negative values do not trigger an alarm if one is set see below). This option is useful for monitoring whether the maximum temperature during all or part of the process remains within specified limits.
Standard Deviation -The standard deviation calculated for all the data points for a given probe.
Minimum Temperature -Lowest temperature reading from a given probe. Useful for indicating when the product does not exceed a required minimum temperature during certain stages of the process (see ‘Calculate’, below).
Time Reached Minimum -The time after the start of the profile run at which a given probe’s minimum temperature was recorded.
Delta T -Can be calculated in two forms, the form used being the one which is currently set in the Reflow Results analysis mode. The two forms are:
Difference between the peak temperatures of the two probes with the highest and lowest peak temperatures.
Temperature of liquidus minus the temperature of the coolest probe when any other probe first reaches liquidus.
The analysis grid shows a link between the identified probes marking the lowest ○ and highest ● temperatures.
Delta T is not calculated when one or more paqfiles are overlaid on the current paqfile and ‘Sort by probe’ mode is selected (see below).

Sort By

When multiple files are overlaid on the graph, data from the probes can be grouped to appear in the analysis grid in different ways.

Calculate

The results displayed in the Analysis Window will normally relate to the whole of the profile run, but you can choose to restrict the analysis to only the zoomed part of the graph, or to certain oven zones.

Parameters

Change the set temperature.

Alarms

Data cells in the Analysis Window can be highlighted automatically, i.e. alarms will be triggered, if their values are outside specified limits.

Alarm Colors

Click the Colors tab to select colors for alarm cells and non-alarm cells.

Max/Min Parameters and Alarms

The default state for these settings can be set as part of the process or recipe file which is applied to the temperature profile data.

The settings can be changed subsequently from the Recipe – Analysis tab of the Process Details dialog (click or select Process > Process Details) or in the Analysis Options dialog (click in the Analysis Window or select View > Analysis Options).

Parameters

If you will be displaying Deviation from Set Temperature in the Analysis Window, give the temperature from which the deviation will be measured.

Alarms

Data cells in the Analysis Window can be highlighted automatically, i.e. alarms will be triggered, if their values are outside specified limits:

Alarm Condition -Select the check boxes to set whether or not alarms will operate for various conditions.
Limit -For any alarm condition you set, enter the value which will trigger the alarm if it is exceeded or not achieved.
Probe -For any selected alarm condition, click on a probe number to remove it from the list of those whose data may trigger an alarm. Click on the number again to restore it. Right-clicking on a probe number removes all probes except that one; right-click on the number again to restore the other probes. If the logger in use has more than 10 probes, click to open a separate list of probes.

Real Time -(For alarm condition ‘Temperature is greater than’ only.) If checked, and if that alarm condition is selected and is triggered during a real-time telemetry run, a red alarm screen will be shown and must be acknowledged by the operator. For each such alarm, an entry will appear in the audit trail.

By clicking the Advanced button, you may also:

Click Add and Remove to modify the list of alarm conditions.
Click an entry in the Alarm Condition column to select from a list of various conditions.

When the advanced alarms setup is in use, clicking Basic disables the option to create additional alarm conditions.

Memos – EDIT > MEMOS

Opens the Memos dialog to add, edit and remove memos.

See: Using Memos

Memos added using this dialog appear on the graph in the middle of the current view. You may then move them by holding Control as you drag the box or arrowhead (box memos) or the line (vertical-line memos).

To edit or remove a memo, you may also right-click on it on the graph.

Merge Wizard – FILE > UTILITIES > MERGE PAQFILES

The Merge Wizard combines data from any number of paqfiles, with any number of probes, to form a single composite file. Paqfiles can be combined as follows.

Merge -Profiles from the files are overlaid on top of one another; profiles are aligned according to their oven start position.
Append -The profiles are added to the end of one another, in the sequence in which the files are selected.
Average -First the profiles are automatically aligned along the time axis according to their shape, then all corresponding data points are averaged to produce a profile which averages the shape of the paqfiles selected.

Merging is done with respect to the time (not distance) axis of the source paqfiles. Process information for the resulting merged paqfile is taken from the first of the files to be selected. The Paqfile Properties dialog for the new merged paqfile lists the source paqfiles.

Click Next after completing each stage of the wizard.

Select Paqfiles

To select paqfiles to merge, click Add and browse to the required files. Use Add, Remove, Move Up and Move Down to organize files in the list.

Merge or Append

Select whether you wish to Merge or Append or Average the profiles (see above).

Open – FILE > OPEN

Paqfile

The Open dialog shows a preview of the selected temperature profile (paqfile). By opening the file you display the temperature profile in the Graph Window and the analysis or raw data in the Analysis Window. The Open dialog lists the contents of the default paqfile directory, though you can browse to any other location; the default directory can be changed.

Go directly to the Open dialog for paqfiles by clicking on the toolbar.

Tolerance Curve

The Open dialog shows a preview of the selected tolerance curve. The dialog opens the Edit Profile section of the Tolerance Curve Wizard, which enables you to edit and save the tolerance curve. The Open dialog lists the contents of the default tolerance curve directory, though you can browse to any other location; the default directory can be changed.

Prediction

By opening a prediction file you display the temperature profile in the Graph Window and the analysis in the Analysis Window; in the Oven Settings grid, oven zone temperatures can be edited to predict and display a revised profile. The Open dialog lists the contents of the default prediction file directory, though you can browse to any other location; the default directory can be changed.

Prediction files produced by using the Rapid Oven Setup module of Insight (available as an additional purchase) which also carry a .PRE extension are not compatible with this software.

SPC

The Open dialog shows a preview of the selected Statistical Process Control file. By opening the file you display the SPC file in the Graph Window and the calculated data in the Analysis Window. The Open dialog lists the contents of the default paqfile directory, though you can browse to any other location; the default directory can be changed.

Process, Oven, Recipe, Product

The Open dialog shows a preview of the selected process, oven, recipe or product file. The dialog opens a modified version of the Process Details dialog which enables you to edit and save the file but not to apply it to a paqfile. The Open dialog lists the contents of the default directory for each file type, though you can browse to any other location; the default directory for each can be changed.

See Creating a Process File for an overview of creating and editing process, oven, recipe and product files.

Thermocouple Correction Factors

The Open dialog shows a preview of the selected thermocouple correction factor file. The dialog opens a modified version of the Thermocouple Correction Factor Wizard which enables you to edit and save the file but not to apply it. The Open dialog lists the thermocouple correction factor files in the default paqfile directory, though you can browse to any other location.

After opening the file, if the thermocouples originate from more than one spool of wire, select the relevant spool number and edit the calibration data as necessary. In the main editing dialog, you may click Print to produce a separate report of the thermocouple correction factor data. The wizard then allows you to save the edited file under the same or a new name.

If a correction factor file has ever been edited, this is shown in the audit trail of any survey to which it is subsequently applied.

Report Template

Starts the Report Wizard, which will take you through the process of editing an existing report template. The template can then be applied before printing a report so that you can easily choose to print reports with different customized contents.

Oven Zones – – OVEN WIZARD

Click the Add button until you have specified the total number of oven zones, then enter the length of each zone as a distance for a conveyorized (reflow or wave solder) oven, or as a time for a batch oven. The start positions of zones are calculated automatically as you enter the zone lengths. You can enter names for the oven zones if you wish.

You may also change the lengths of the zones by dragging their boundaries on the oven diagram.

By default, all zones are assumed to be heated (marked ● in the oven zones grid). Any unheated zones can be specified: click on the relevant cell in the Zone column to toggle between heated and unheated (marked ●); unheated zones can be set only at the start or end of an oven, and are not given a zone number.

To insert a zone within those already created, click in the grid immediately below the position of the new zone, and then click Insert.

To remove a zone, click on its name or length in the grid and then click Remove.

Click to see an enlarged view of the oven diagram in a separate window and then re-size the image as you wish by dragging on the window’s edges or by maximizing it.

The actual position of the oven start may or may not be important. This depends on the method to be used after the profile run to adjust the oven start and thereby match the profile data to the positions of the oven zones.

Oven Setup Wizard –

In order to create an oven file, the Oven Setup Wizard takes you through the necessary steps one after the other (click or select Tools > Wizards or File > New > Oven).

See also Creating a Process File for other ways of setting up an oven file.

The procedure is largely self-explanatory: enter information as prompted by the wizard, then click Next at the end of each stage.

Specify the type of oven: conveyorized (Reflow or Wave or Wave with Pallet) or Batch. These differ in the way that oven zones (see below) are defined, and in the analyses that will be performed on them.

The oven file created by the wizard will be specific to the oven type specified here.

Save Oven – – OVEN WIZARD

Data for your oven file has now all been entered and you must give it a filename. The filename will be saved with a .OVN extension.

There is a default directory in which oven files are stored, but you can browse to a directory of your choice.

You can protect the file from unauthorized editing by giving it a password.

View details of the Peak Difference analysis mode

Overlay – VIEW > OVERLAY

Overlaying temperature profiles within the same graph is useful for purposes of comparison, and to check that individual profiles fall within specified limits.

The Overlay dialog is also available from the graph right-click menu.

In order that the overlay be meaningful, it is essential to have defined accurately the oven start for all curves and that this has been applied consistently, i.e. the oven start position must be the same for all curves. Any differences in line speed between the temperature profiles must also be properly accounted for (see ‘Align Overlay X-axis By’, below).

If you are using Peak Difference analysis mode, overlaying files makes important differences to the analysis and presentation of data.

To select curves to be overlaid, click Add and browse to the required files. Turn the display of each curve on or off with the Show checkbox. Click Browse next to a selected file to replace it with another.

Paqfiles

Up to ten paqfiles can be overlaid on the current paqfile.

Probe numbers and probe names in the overlaid paqfiles are maintained unchanged: they are shown in the Probe Key beside the graph, and can be viewed and edited in the Edit Probe Names dialog (click in the Analysis Window). The traces for all probes of a given probe number are shown in the same color but in a different tint of that color.

Align Overlay X-axis By

By default, the x-axes (horizontal axes) of overlaid temperature profiles are aligned with each other by time. If the line speeds used in the different profiles are the same, this ensures that all data gathered at any given point in the oven will correspond in position on the graph, and both the time and distance scales on the x-axis will then correctly represent the positions of data points.

However, if data for overlaid temperature profiles have been gathered with the oven set at different line speeds from the base paqfile (or from each other), the data from such profiles will not align correctly on the graph with respect to the total length of the oven and the positions of the oven zones; thus you should then opt to align by distance. The distance scale (oven bar) on the x-axis will then be correct for all paqfiles displayed, but the time scale will be correct only for the base paqfile (and for any other overlaid paqfiles with the same line speed); a warning message will appear above the data grid in the Analysis Window.

Tolerance Curves

Up to four tolerance curves can be overlaid on the current paqfile. You will probably not want to see more than one tolerance curve overlaid at once, but you may select here your most frequently used curves in order that they can be applied quickly when needed.

You may also use the Process Details dialog (click or select Process > Process Details) to select which tolerance curves to show and, if you wish, to incorporate them in a process or recipe file. There you can also select whether to show an alarm if data from one or more probes fall outside a selected tolerance curve.

A tolerance curve and the use of an alarm can be selected when a process or recipe file is created with the wizards.

Use the Graph Options dialog (on graph right-click menu, or select View > Graph Options) to choose colors for the tolerance curves and whether or not to display the inner and/or outer bands and the curve’s initial profile.

If the process details have been password-protected, a warning message appears in the dialog and if editing is not currently enabled and the tolerance curve overlays thus cannot be changed the message appears in red and a symbol is displayed. Use the Process Details dialog to enable/disable editing and add/remove/change the password.

Paqfile Directories, Process File Component Directories – TOOLS > OPTIONS

By default, your data and analysis files are organized in a logical directory system. A typical installation of default directories, with file extensions, is as follows:

Paqfiles, Prediction files, SPC files, Thermocouple correction factor files	C:\Program Files\Datapaq Insight\Reflow\Paqfiles	.PAQ, .PRE, .SPC, .CAL
Process files	C:\Program Files\Datapaq Insight\Reflow\Process	*.PRO
Tolerance curves	C:\Program Files\Datapaq Insight\Reflow\Tolerance	*.TOL
Oven files	C:\Program Files\Datapaq Insight\Reflow\Ovens	*.OVN
Recipe files, Analysis parameters files	C:\Program Files\Datapaq Insight\Reflow\Recipes	.REC, .ANA
Product files	C:\Program Files\Datapaq Insight\Reflow\Products	*.PRD
Reports, Report templates	C:\Program Files\Datapaq Insight\Reflow\Reports	.PDF, .RTP

Use of the default directory structure is recommended, but you may specify your own, e.g. to allow files to be stored on a network. To choose your own default directories, click the relevant Browse button to locate them.

Search Sub-directories -This option affects wizard file-selection dialogs, as well as other open/save dialogs when the relevant Fix Directory option has been selected (see below). When checked, such dialogs will list suitable files found in sub-directories below the default directory as well as those in the default directory itself.

Fix Directory -When checked, select/open/save dialogs will contain only a list of files of the given type contained in the specified directory. All files of the given type will be saved to, and can be selected only from, that directory. It will not be possible to browse to another directory.

Fix Directory is useful if you wish to ensure that files of a given type are always stored in the same location, particularly if different users will be operating the system from time to time.

Paqfile Properties – FILE > PROPERTIES

The Paqfile Properties dialog is also available from the graph right-click menu.

Details

The dialog displays key details about the currently open paqfile concerning data-collection, the logger used and the process applied.

Name -The name under which the paqfile has been saved.
Operator –Name of the paqfile’s originator, as entered in the Notes dialog.
Number of Probes –The number of probes on the logger used for the profile run.
Sample Interval -Time between data points, as set during logger reset.
Data Loaded -Date and time at which the profile data were downloaded from the logger to the PC.
Collection Started -Date and time that data collection started, i.e. the point at which the logger was triggered.
Trigger Mode -The means used to start the logger recording data.
Trigger Time/Temperature -Date and time, or temperature, set to trigger data collection (if an appropriate trigger mode was set).
Max Internal Temperature -Highest value that the internal temperature of the logger reached during the profile run.
Logger ID –Identification number of the logger used for the profile run. This is incorporated automatically in the paqfile.

If the paqfile was created during a telemetry run, there are also entries for:

Data Received -Percentage of transmitted data packets which were successfully received.
Most Packets Lost At -Area in the data where the largest number of packets was missed (and number of packets missed at this time).

Click Advanced to display the profile of the logger’s internal temperature: this appears in the Graph and Analysis Windows as if it is data from an additional probe. (Not available for all logger types.)

Click Alarms/Alerts to display the Alarm/Alert Summary dialog.

The dialog gives a chronological list of the times at which alarms (shown by ) and alerts () were triggered during data-collection; a short description of each is given. If an alarm or alert was acknowledged by the user when it occurred during real-time data-collection, the time of the acknowledgement and the user’s login name is given. If any invalid data is present in the paqfile, this is noted at the end of the list.
Click Analysis Alarms to expand/contract the dialog and show/hide a list of other alarms which have been triggered: analysis alarms and tolerance alarms (for out-of-tolerance profile data). This list is also shown on the Alarms tab in the Analysis Window.

Click Audit Trail to access a summary of key events in the history of the paqfile.

Process

A name for the process currently applied is shown if:

A process file has been applied, or if
The process currently applied has been given a name on the Overview page of the Process Details dialog.

Click Apply New to apply a new process file, or Edit to open the Process Details dialog.

If the currently displayed paqfile is the result of merging other paqfiles, the names of the source paqfiles are given; some of the properties listed above are omitted, but can be found in the Paqfile Properties of the source paqfiles.

Peak Difference – – VIEW > ANALYSIS OPTIONS

This analysis mode identifies the two probes which recorded temperatures with the biggest difference at any single point in the profile. It gives the value of the difference and the time in the profile at which it occurred. Thus it can be used to identify where the worst instances of unevenness of heating are occurring on the product.

To print the analysis results, select File > Print Options from the main menu.

The analysis grid shows a link between the two identified probes, and their temperatures.

By default, the analysis will consider the profile as a whole, but you can force it to consider:

Only certain probes (e.g. to give you the magnitude and timing of the peak temperature difference between any two probes), and/or
Only a certain part of the profile.

To select the probes and the region of the profile which you wish to include in the calculation, and the alarm criteria, click (or select View > Analysis Options) to display the Analysis Options dialog.

Excluding probes

To turn probes off, click on the probe buttons in the analysis grid or in the Analysis Options dialog. The analysis will then apply only to those that remain. If there are too many probes to display all at once in the dialog, a More button will appear; click this to see a full selectable list of probes.

Analyzing only part of the profile

Either:

Zoom into your chosen part of the graph by dragging out a rectangle (from top left to bottom right) over the selected area. Data shown in the Analysis Window then apply only to the region of the graph that has been selected for zoom. Return to the normal view and restore analysis of the whole profile by double-clicking on the graph. Or
Restrict the analysis by oven zone.

Sort By

Only relevant when multiple files are overlaid on the graph. Selects how data from the different probes are grouped in the analysis grid.

File Groups data for the probes by file, i.e. probes 1 to 6 for file 1, then probes 1 to 6 for file 2, etc.
Probe Groups data for the probes by probe number, i.e. all no. 1 probes from all files, then all no. 2 probes from all files, etc.

Peak differences are shown separately within each group, whether by file or by probe. The analysis can be made to consider the profile as a whole, or only certain probes, or only a certain part of the profile, as above.

Calculate

Alarms

Data cells in the Analysis Window can be highlighted automatically, i.e. alarms will be triggered, if their values are outside specified limits.

Alarm Colors

Click the Colors tab to select colors for alarm cells and non-alarm cells.

Peak Difference Alarms

The default state for these settings can be set as part of the process or recipe file which is applied to the temperature profile data.

Alarms

Data cells in the Analysis Window can be highlighted automatically, i.e. alarms will be triggered, if their values are outside specified limits:

Alarm Condition -Select the check boxes to set whether or not alarms will operate for various conditions.
Limit -For any alarm condition you set, enter the value which will trigger the alarm if it is exceeded or not achieved.

Print Options – FILE > PRINT OPTIONS

You can produce a printed report of your currently open paqfile. Choose here the items to include on it, and then click Print or select File > Print. If you wish, preview it with File > Print Preview.

To email a PDF of the printed report, select File > Print to PDF.

If you wish to manipulate or display the analysis results or raw data using another application, you may copy them into a file (select Edit > Copy).

Settings chosen in Print Options are effective globally, i.e. they remain in force for all files until changed again. The settings are not stored within individual paqfiles.

Report Sections

Report Type –Choose the type of report you wish to generate:

Graph and Analysis Results -Show graph and the items checked under Additional Information and Analysis Results (see below).
Graph Only -Show only the graph: Additional Information and Analysis Results (see below) are not included. The graph will appear just as it does on screen at the time of printing, i.e. with the same state of zoom, overlays, number of probe traces, zone boundaries, memos, etc.; to change the color, style or thickness of probe traces on the graph, select View > Graph Options > Profile Options, or use the right-click menu.
View Data -Show only the results of the View Data analysis mode, i.e. the raw data from the temperature profile (see also below).
Analysis Results -Show the items checked under Analysis Results (see below).
Audit Trail -Show only the audit trail.

Sort By -Select how data from the different probes are grouped as they appear in the grid of data analysis results (only relevant with multiple files overlaid on the graph):

Probe -Groups data for the probes by probe number, i.e. all no. 1 probes from all files, then all no. 2 probes from all files, etc.
File -Groups data for the probes by file, i.e. probes 1 to 6 for file 1, then probes 1 to 6 for file 2, etc.

The setting made here determines the sort order for the printed report only; it overrides the setting made for the screen display.

Print, Printer Setup – FILE MENU

After setting options for a printed report on your paqfile, select your printer, paper size and orientation, and number of copies. You may then click OK in the Print dialog to print the report.

The Properties button takes you to a setup dialog specific to the selected printer.

Edit Probe Names – – EDIT > PROBE NAMES

You may edit the probe names. Changes are reflected in the Probe Key alongside the graph.

You can reach the Edit Probe Names dialog directly by clicking in the Analysis Window. Probe names can also be changed on the Product tab of the Process Details dialog (click or select Process > Process Details). If changes are then saved as part of the process file which is applied to new temperature profile data, the new probe names will appear automatically in those new paqfiles.

Probe Toolbar – VIEW > PROBE TOOLBAR

Displays or hides the probe toolbar. Click on individual buttons to turn probes on and off, i.e. to remove their data from the graph and from the data grid; the data are then also removed from the calculations in the analysis data grid. Click on a probe button again to restore its data. Right-clicking on a probe button removes all probes except that one from the graph and from the analysis; right-click on the button again to restore the other probes.

Probes can also be turned on and off by clicking the probe numbers in the analysis grid.

Probes names are shown in the Probe Key to the right of the graph, and also appear when the cursor is held briefly over the probe number in the analysis grid.

To change the color, style or thickness of probe traces on the graph, select View > Graph Options > Profile Options, or use the right-click menu.

Probe Window – VIEW > PROBE WINDOW

Opens the Probe Window, which shows the product diagram or picture (if one has been used), together with the probes in position.

To add a product picture, or to change the product picture or rotate it, or to move the probe positions, use the Product tab of the Process Details dialog (click or select Process > Process Details).

Re-size the product picture as you wish by dragging on the window’s edges or by maximizing it.

Oven – – PROCESS > PROCESS DETAILS

On this tab of the Process Details dialog

View notes on the oven Specify number and lengths of oven zones Save the current details as an oven file

If a symbol is displayed and the information in the dialog is not editable, the process details have been password-protected.

Oven Details

Any process file, oven file, recipe file or product file you save from the Process Details dialog will be specific to the oven type specified here.

For reference, you may enter the oven’s name. You can also add any comments which may be useful.

You do not need to provide a name for the oven, but it is good practice to do so:

This will identify the oven when you view or edit its details later in this dialog.
If these oven details are saved as an oven file, and that file is incorporated in a process file, the name you enter will also appear in the preview field when you select the process file in a File Open dialog.

Save As will save, as an oven file, the details currently displayed on this dialog page. The suggested filename is that of the oven’s name (as entered on this page). The filename will be saved with a .OVN extension. There is a default directory in which oven files are stored, but you can browse to a directory of your choice.

Using this method to create an oven file, it is not possible to protect it from later unauthorized editing by giving it a password: to do this you must create it with the Oven Setup Wizard or as part of the Process Setup Wizard. You may, however, password-protect a process file created with the Process Details dialog (on the Overview tab).

Oven Zones

The diagram shows the number and position of the oven zones. Click and drag on a part of the oven diagram (from top left to bottom right) to zoom into it. To restore the normal view, double-click the diagram.

Click to see an enlarged view of the oven diagram in a separate window and then re-size the image as you wish by dragging on the window’s edges; you can also zoom further in to parts of this enlarged view, as above.

You may also change the lengths of the zones by dragging their boundaries on the oven diagram.

Changes to the oven zones for the currently displayed paqfile may also be made with the Adjust Zone Lengths dialog (on the graph right-click and Process menus): here you may also select a probe trace to display on the oven diagram, which can assist in fitting the oven zones to the trace.

To insert a zone within those already created, click in the grid immediately below the position of the new zone, and then click Insert.

To remove a zone, click on its name or length in the grid and then click Remove.

Process Name -For reference, you may enter a name for the process.

You do not need to provide a name for the oven, but it is good practice to do so:

The name entered here will be used as a suggestion for the filename if you save these process details as a process file in this dialog (see ‘Save As’, below).
This will identify this process when you view or edit its details later in this dialog.
The name will appear above the graph.

Open -Allows you to open an existing process file. That process file’s details are then displayed in the Process Details dialog but are not applied to the currently viewed paqfile until you click OK.

Save As -Use this to save, as a process file, all the details currently displayed in the Process Details dialog. The suggested filename is that of the process name (as entered on this page). The filename will be saved with a .PRO extension. There is a default directory in which process files are stored, but you can browse to a directory of your choice. If the process details are password-protected, editing must be enabled (see below) before Save As can be used.

All process details displayed in the Process Details dialog will be saved with the currently displayed paqfile when the paqfile is saved, but they will not form part of a separate process file unless they are saved here.

Clear -Click to remove all the important process details (oven data, main recipe settings, tolerance curves applied, product details) that are presently applied to the paqfile. This change does not become permanent until the paqfile is saved.

Notes -Create or edit notes of your own which will be saved as part of the process file. They can be viewed in this dialog and are included in the printed report.

To create or edit notes which will be saved with the current paqfile (rather than with the process file), select Edit > Notes from the main menu.

Password -You may password-protect the process details against unauthorized editing.

Passwords are case-sensitive but do not have a minimum number of characters.

To set password-protection: click ‘Password’ and enter your password in both the boxes. A warning message in red then appears alongside the ‘Password’ button, and settings on all pages of the dialog become uneditable. In order to keep password-protection when you open the current paqfile in future, you must now click ‘OK’ to close the Process Details dialog and then save the paqfile.
To enable editing of the process details: click ‘Password’ and enter the password; the warning message changes to black.
To reinstate password-protection, with the same or a different password: set the password afresh, as above (though you then need to save the paqfile only if you have changed the password).
To remove the password: enable editing and then set the password afresh, entering nothing in both boxes.

If the paqfile is closed with or without being saved with a password set and editing enabled, password-protection remains in effect next time the paqfile is opened, i.e. editing of the process details will not be possible without entering the password.

If the process details are password-protected, process files which are created from the Process Details dialog using the ‘Save As’ button (see above) will also require the same password before they can be edited.

Oven, recipe and product files created using the ‘Save As’ buttons on the respective pages of the Process Details dialog cannot be passworded; these files can be passworded only by creating them afresh with the wizards.

Process Summary -Summarizes the oven, recipe and product details that are currently displayed on other pages of the Process Details dialog. A warning message appears below the recipe summary if the oven and recipe have differing numbers of oven zones and are thus incompatible.

Apply New Oven/Recipe/Product -Allows you to open existing oven, recipe and product files. Those files’ details are then displayed on the appropriate pages of the Process Details dialog but are not applied to the currently viewed paqfile until you click OK.

Click the oven or product previews to see enlarged views in a separate window and then re-size the image as you wish by dragging on the window’s edges or by maximizing it.

The setup wizards are available from this dialog if you wish to use them to create new oven, recipe and product files.

Product Details

For reference, you may enter details of the product name and family. You can also add any comments which may be useful.

You do not need to provide a name and family for the product, but it is good practice to do so:

This will identify the product when you view or edit its details later in this dialog.
If these product details are saved as a product file, and that file is incorporated in a process file, the name you enter will also appear in the preview field when you select the process file in a File Open dialog.

Save As will save, as a product file, the details currently displayed on this dialog page. The suggested filename is that of the product’s name (as entered on this page). The filename will be saved with a .PRD extension. There is a default directory in which product files are stored, but you can browse to a directory of your choice.

Using this method to create a product file, it is not possible to protect it from later unauthorized editing by giving it a password: to do this you must create it with the Product Setup Wizard or as part of the Process Setup Wizard. You may, however, password-protect a process file created with the Process Details dialog (on the Overview tab).

Probe Alignment

For reflow ovens (but not for wave solder ovens), choose here whether or not to align probe data, and how this is to be done:

Align Probes -If checked (and if Auto Align is not checked), probe data will be aligned according to the exact relative positions of the probes, as provided here by the user. Otherwise, no adjustment is made for any differences in the probe positions.
Auto Align Probes -If checked, positions of the probe traces are adjusted automatically, according to their shape. This is done when the process file or product file is applied to the paqfile after the data are downloaded from the logger.

Probe profiles can also be aligned by eye separately from the use of a process or product file after the paqfile has been obtained. This is done using the Adjust Probe Alignment dialog (on Process menu or graph right-click menu).

For reflow ovens (but not for wave solder ovens), if you have checked Align Probes but not Auto Align Probes (see above), you must enter each probe’s X and Y coordinates (from an origin at top right of the product) in order that the alignment of data can be carried out. Alternatively, drag the yellow probe markers on the diagram; positioning by eye is much easier if a picture of the product is being used. Coordinates in the grid update as the probe markers are moved, and vice versa.

You may enter descriptive names for the probes.

If you have a picture of the product in BMP, JPG, GIF or PNG format you can insert it here. This can either be simply for identification and reference, or it can help you to locate the positions of the thermocouple probes on it in order that the analysis can compensate for the time delays between different probes passing through the oven. The picture should be to scale, from above or to the side of the product.

If you have included a picture of your product, you can click to rotate it (clockwise, 90 at a time) so that the edge which enters the oven first is to the right. To remove a picture, click .

You must enter the size of your product if:

You wish probe alignment to be calculated from probe positions (see above), or
You have included a picture of it (or its proportions may be distorted when it is displayed).

Otherwise the default size need not be changed (but it must not be zero).

The aspect ratio of your picture, as displayed, will reflect the product dimensions you have specified. Thus, if the relative dimensions of the picture do not exactly match those you have given for the product, the aspect ratio of the picture will change.

If a symbol is displayed and the information in the dialog is not editable, the process details have been password-protected.

Analysis Mode

Analyses can be performed on the profile data you gather, and, as part of this, alarms can be set up to highlight data which are outside specified limits. For most of the analysis modes you can specify various parameters and set which alarms are to be operational and what their alarm conditions are to be (by default, all alarms are off).

In the Analysis box, select the analysis mode whose parameters/alarms you wish to change, and select options and/or enter values.

The settings contained on this tab of the Process Details dialog parameters and alarms for all analysis modes can be saved in an analysis parameters file in order that they can easily be applied to any paqfile or process. Click Save As to create or update the file; analysis parameters files are saved with a .ANA extension and stored in the default recipe file directory, but you can browse to a directory of your choice. Click Open to apply an existing analysis file to the currently-open paqfile.

Options set here can also be applied to paqfiles individually using the Analysis Options dialog for the relevant analysis (after selecting the analysis tab at the bottom of the screen, click or select View > Analysis Options) or the Recipe – Analysis tab of the Process Details dialog (click or select Process > Process Details). However, if you will be applying the same options to a number of paqfiles, it is quicker and more convenient to do this by making them part of a process or recipe file.

Analyses

Use the Analysis Options dialog to turn the display of these options on or off.

Rise Time -Time taken for the temperature to rise from the lower to the upper temperature within the specified range. Enter temperatures in the ‘From’ and ‘To’ boxes if you wish to use this option. NB If the upper temperature of the specified range has not been reached, rise time is calculated up to the peak value achieved and is then marked with an asterisk * in the analysis grid.
Rise Time to Peak -Time taken for the temperature to rise from the lower specified temperature to the peak value. Enter the lower temperature in the ‘From’ box.
Delta T -Can be calculated in two forms. Select one:
Difference between the peak temperatures of the two probes with the highest and lowest peak temperatures.
Temperature of liquidus minus the temperature of the coolest probe when any other probe first reaches liquidus.

Using this method to create a recipe file, it is not possible to protect it from later unauthorized editing by giving it a password: to do this you must create it with the Recipe Setup Wizard or as part of the Process Setup Wizard. You may, however, password-protect a process file created with the Process Details dialog (on the Overview tab).

Oven Settings

Line Speed -For a conveyorized oven or wave solder oven, enter the oven’s line speed so that the results analysis can display the temperature profile correctly relative to the oven length and to the positions of the oven zones.

Variable Line Speed -If the line speed differs between oven zones, select this option, click Setup, and enter the line speed for each zone.

For reference, you may add details of the oven convection level and line width though these do not affect the presentation or analysis of the temperature profile.

When variable line speeds have been set up, overlay of temperature profiles by distance is not possible.

For a rework oven, there are no oven settings to enter.

Oven Start

This matching of data with oven zone positions is done by adjusting the position of the oven start relative to the data. This can either be done automatically after the profile data have been gathered by analyzing the shape of the profile, or various trigger modes can be used (click Specified By):

Temperature Reached -Oven start is set to be the point at which the temperature of any probe rises above a temperature which you specify here.
Automatic (default) -Oven start is determined automatically, based on the point at which the temperature starts to rise rapidly as it enters the oven.
External Trigger -Oven start is relative to an external event, e.g. a Hall-effect switch which is triggered as the product passes a fixed point near the oven entrance.
User -Oven start is set to be a specified distance or time from the start of the data. This allows the user to make an individual judgement about where the oven should be considered to start relative to the point at which data starts to be collected by the logger.

Defined By -Specify here whether distance or time (measured from the start of data collection) will be used to fix the point at which the oven starts.

Oven Start At -Enter the distance or time which should elapse between the start of data collection and the oven start. A distance measurement must be based on the distance covered by the product, according to the line speed set, after data collection starts.

Oven start can also be set interactively by eye separately from the use of a process or recipe file after the paqfile has been obtained. This is done using the Adjust Oven Start dialog (on Process menu or graph right-click menu).

All the other oven start adjustments listed above (except External Trigger) can also be made with the Adjust Oven Start dialog, but in this case the adjustment must be made individually for every paqfile.

Oven Zone Temperatures

In the grid, enter the oven zone temperatures for the lower and upper heaters of each zone that you wish to use.

If you wish the settings for the upper and lower heaters to be the same, enter the Lower figure, then press cursor down to the next zone – the Upper figure is entered automatically.

Instead of entering settings in the grid, you may drag the temperature bars up and down on the oven diagram. There are separate bars for the lower and upper heaters. The corresponding figures then appear in the grid.

The number of oven zones shown, and their names, are taken from the information entered earlier in the wizard, or from the oven file you are using.

Setup Default Temperature Axis -Check this option to specify a preference for zooming along the graph’s y-axis (temperature axis) when the process zoom is applied to the graph. Click ‘Setup’ to choose the temperature range to be shown, and the tick intervals on the axis.

Recipe – Tolerances – – PROCESS > PROCESS DETAILS

On this tab of the Process Details dialog

Use a tolerance curve to assess whether the temperature profile is within acceptable limits.

If a symbol is displayed and the information in the dialog is not editable, the process details have been password-protected.

A tolerance curve provides an envelope of acceptability against which to compare the temperature profile from a product’s run through the oven.

Use the Add and Remove buttons to maintain your list of tolerance curves, and check Show boxes to choose which ones will appear on the graph.

Check Profile is Within Tolerance -Select whether to show an alarm if data from one or more probes fall outside a selected tolerance curve; choose the tolerance curve number in the box.

You may also choose here to:

Edit one of your selected curves.
Create a new curve with the Tolerance Curve Wizard.

You may also use the Overlay dialog (on graph right-click menu, or select View > Overlay) to select which tolerance curves to show. You can also choose there to overlay other paqfiles and a target profile.

Data Analysis – – PROCESS/RECIPE WIZARD

Analyses can be performed on the profile data you gather, and, as part of this, alarms can be set up to highlight data which are outside specified limits. As part of your process and/or recipe file, you can for most of the analysis modes specify various parameters and set which alarms are to be operational and what their alarm conditions are to be (by default, all alarms are off).

To change options: in the dialog list, select the first one you wish to change, and click Next.

Or select Skip if you wish to accept the default options for all analyses.

Options set here, in a process or recipe file, can all be applied to paqfiles individually using the Analysis Options dialog for the relevant analysis (after selecting the analysis tab at the bottom of the screen, click or select View > Analysis Options) or the Recipe – Analysis tab of the Process Details dialog (click or select Process > Process Details). However, if you will be applying the same options to a number of paqfiles, it is quicker and more convenient to do this by making them part of a process or recipe file.

Number of Probes – – PROCESS/PRODUCT WIZARD

Enter the number of thermocouple probes that will be used to monitor this product.

With wave solder, the number of probes is fixed; thus this stage of the wizard is not shown.

Oven Settings – – PROCESS/RECIPE WIZARD

Variable Line Speed -If the line speed differs between oven zones, select this option and enter the line speed for each zone.

For reference, you may add details of the oven convection level and line width though these do not affect the presentation or analysis of the temperature profile.

When variable line speeds have been set up, overlay of temperature profiles by distance is not possible.

For a rework oven, there are no oven settings to enter.

Oven Start – – PROCESS/RECIPE WIZARD

Temperature Reached -Oven start is set to be the point at which the temperature of any probe rises above a temperature which you specify here.
Automatic (default) -Oven start is determined automatically, based on the point at which the temperature starts to rise rapidly as it enters the oven.
External Trigger -Oven start is relative to an external event, e.g. a Hall-effect switch which is triggered as the product passes a fixed point near the oven entrance.
User -Oven start is set to be a specified distance or time from the start of the data. This allows the user to make an individual judgement about where the oven should be considered to start relative to the point at which data starts to be collected by the logger.

Defined By -Specify here whether distance or time (measured from the start of data collection) will be used to fix the point at which the oven starts.

Oven start can also be set by eye separately from the use of a process or recipe file after the paqfile has been obtained. This is done using the Adjust Oven Start dialog (on Process menu or graph right-click menu).

Oven Zone Temperatures – – PROCESS/RECIPE WIZARD

In the grid, enter the oven zone temperatures – for the lower and upper heaters of each zone – that you wish to use.

If you wish the settings for the upper and lower heaters to be the same, enter the Lower figure, then press cursor down to the next zone – the Upper figure is entered automatically.

The number of oven zones shown, and their names, are taken from the information entered earlier in the wizard, or from the oven file you are using.

Oven Zones – – PROCESS/OVEN WIZARD

You may also change the lengths of the zones by dragging their boundaries on the oven diagram.

To insert a zone within those already created, click in the grid immediately below the position of the new zone, and then click Insert.

To remove a zone, click on its name or length in the grid and then click Remove.

Click to see an enlarged view of the oven diagram in a separate window and then re-size the image as you wish by dragging on the window’s edges or by maximizing it.

The actual position of the oven start may or may not be important. This depends on the method to be used – after the profile run – to adjust the oven start and thereby match the profile data to the positions of the oven zones.

Process Setup Wizard –

In order to create a process file, the Process Setup Wizard takes you through the necessary steps one after the other (click or select Tools > Wizards or File > New > Process).

See also Creating a Process File for other ways of setting up a process file.

As a process file is composed of oven, product and recipe information, you will follow essentially the same stages as those of the Oven, Recipe and Product Wizards, in sequence. The procedure is largely self-explanatory: enter information as prompted by the wizard, then click Next at the end of each stage.

The process file, oven file, recipe file and product file created by the wizard will be specific to the oven type specified here.

Probe Positions – – PROCESS/PRODUCT WIZARD

For reflow ovens (but not for wave solder ovens), choose here whether or not to align probe data, and how this is to be done:

Align Probes -If checked (and if Auto Align is not checked), probe data will be aligned according to the exact relative positions of the probes, as provided here by the user. Otherwise, no adjustment is made for any differences in the probe positions.
Auto Align Probes -If checked, positions of the probe traces are adjusted automatically, according to their shape. This is done when the process file or product file is applied to the paqfile after the data are downloaded from the logger.

In the grid you may enter descriptive names for the probes.

If you have included a picture of your product, you can click to rotate it (clockwise, 90 at a time).

Click Large View to see a bigger view of the product image in a separate window and then re-size the image as you wish by dragging on the window’s edges or maximizing it. This will enable you to see the probes more easily and to position them more precisely.

Product Picture and Size – – PROCESS/PRODUCT WIZARD

If you have a picture of the product in BMP, JPG, GIF or PNG format you can insert it here. This can either be simply for identification and reference, or it can help you to locate the positions of the thermocouple probes on it in order that the analysis can compensate (by probe alignment) for the time delays between different probes passing through the oven. The picture should be to scale, from above or to the side of the product.

After inserting your picture, you can click to rotate it (clockwise, 90 at a time) so that the edge which enters the oven first is to the right. To remove a picture you have just inserted, click .

You must enter the size of your product if:

You wish probe alignment to be calculated from probe positions, or
You have included a picture of it (or its proportions may be distorted when it is displayed).

Otherwise the default size need not be changed (but it must not be zero).

Reflow Analysis – – PROCESS/RECIPE WIZARD

Entering the liquidus temperature permits analysis of the part of the temperature profile which lies above that value.

To add to the Reflow Results section of the data analysis, you can choose to display the following.

Rise Time -Time taken for the temperature of each probe to rise from one specified temperature to another. Enter the upper and lower temperatures if you wish to use this option. (Use the Analysis Options dialog to turn the option on or off.)

Rise Time to Peak -Time taken for the temperature to rise from the lower specified temperature to the peak value. Enter the lower temperature in the ‘From’ box.

Delta T -Can be calculated in two forms. Select one:

Difference between the peak temperatures of the two probes with the highest and lowest peak temperatures.
Temperature of liquidus minus the temperature of the coolest probe when any other probe first reaches liquidus.

Save Oven – – PROCESS/OVEN WIZARD

Configure Receivers – – VIEW > RADIO RECEIVERS > RADIO FREQUENCY WIZARD

Applies to TM21 radio-telemetry system only. For older systems, see your hardware manual.

Now the frequency has been chosen, click Configure Receivers to set this frequency in all receivers currently attached. This frequency will then be used automatically also by the logger’s transmitter.

Search for Best Frequency – – VIEW > RADIO RECEIVERS > RADIO FREQUENCY WIZARD

Applies to TM21 radio-telemetry system only. For older systems, see your hardware manual.

Before Insight searches for frequencies, ensure that:

The primary receiver is connected to the PC via a USB port, and to its power supply and that the other (secondary) receivers (if any) are connected to the primary receiver.
The logger(s) are not transmitting (i.e. that logging has not been triggered).

After clicking Search, frequencies are listed with a star rating according to their ability to avoid external interference. To repeat the search, click Search again.

You will normally select the highest-rated frequency: click on it in the list, and then click Next.

Select Radio Frequency – – VIEW > RADIO RECEIVERS > RADIO FREQUENCY WIZARD

Applies to TM21 radio-telemetry system only. For older systems, see your hardware manual.

Datapaq telemetry systems are supplied with transmitter(s) and receiver(s) configured so that they can communicate. However, after connecting receivers and antennae, the system’s radio frequency can be changed if thought necessary. This is done using the Radio Frequency Wizard, which guides you through the process of selecting and setting up a suitable frequency for the receivers; this frequency will then be used automatically also by the logger’s transmitter.

If you already know the transmitter frequency you wish to use, you may select it as part of resetting the logger: select Logger > Reset, and click ‘Advanced Telemetry‘. but that method is not recommended for most users as it does not ensure that transmitter and receivers are set to the same frequency.

To start the wizard, click or select View > Radio Receivers > Radio Frequency Wizard.

The Radio Frequency Wizard is not available when the Radio Receivers dialog is displaying a warning.

The procedure is largely self-explanatory: enter information as prompted by the wizard, then click Next at the end of each stage.

In this first wizard stage, specify how you wish to choose the frequencies:

Use specific frequency The initial frequency shown is that currently in use by the receivers, which you may now change. In this case, when you click ‘Next’, the wizard will proceed to configure the receivers.
Search for the best frequency Insight will search for suitable frequencies and rank them according to their susceptibility to external interference.

Radio Receivers – – VIEW > RADIO RECEIVERS

Applies to TM21 radio-telemetry system only. For older systems, see your hardware manual.

The Radio Receivers dialog is used to inform Insight of the radio-telemetry receivers attached, and to provide confirmation of correct connection. The system’s radio frequency can also be changed from this dialog.

Reach the Radio Receivers dialog directly by clicking

on the toolbar.

To check the status of receivers while they are receiving data during a profile run, use the Real Time Tool.

If Insight has not previously been set up with radio-telemetry receivers, or if the setup has been changed:

Ensure the primary receiver is connected to the PC via a USB port, and to its power supply and that the other (secondary) receivers (if any) are connected to the primary receiver.
Click Detect to make Insight find the receivers, and to display information about them.

The dialog then shows:

The radio frequency currently in use.
The serial number of each receiver connected.

Where two or more secondary receivers are connected, their sequence in the dialog will not necessarily be the same as that in which they are connected. If you wish, you may correct this: click on the image of a receiver and drag it to the correct position.

If a receiver becomes disabled, due to a connection problem or power loss, a warning is displayed on the icon for that receiver. If preferred, you may remove that receiver’s icon from the display: right-click on the icon and select ‘Remove’.

The system’s radio frequency can be changed if thought necessary: click Radio Frequency Wizard.

Real Time Tool – – VIEW > REAL TIME TOOL

Applies to TM21 radio-telemetry system only. For older systems, see click here.

For use during a radio-telemetry profile run, this dialog shows:

The status of receivers and loggers in use.
Real-time confirmation of data being transmitted and received, and its quality.

Reach the Real Time Tool dialog directly by clicking on the toolbar.

To customize the Graph Window display as data is being received, see Running a Profile Using Telemetry.

If using the TM21 radio-telemetry system:

For your first radio-telemetry run, or if your arrangement of receivers has been changed, open the Radio Receivers dialog and click ‘Detect’ in that dialog before the run and before resetting the logger(s) to inform Insight of the receivers attached.
If the system’s radio frequency needs to be changed, this is done before a profile run is started by using the Radio Frequency Wizard (select View > Radio Receivers). For setting frequency in older radio-telemetry systems, see your hardware manual.

Information is transmitted from the logger as data-packets (i.e. sets of data from all of the logger’s probes at a given instant, determined by the sample interval specified). The TM21 radio-telemetry system can transmit a given data-packet multiple times, interleaving this with other data-packets, thus greatly increasing the security of data transmission.

The number of times a data-packet is transmitted can be adjusted during the logger reset process: select Logger > Reset > Advanced Telemetry. Increasing the number of transmissions can overcome momentary interference such as that caused by the switching of large electrical loads, but it consumes more power and so will shorten the logger battery’s operation time; it should thus be used with caution. Typically, three transmissions is a good compromise for most industrial processes.

Click Contract to remove the receivers from the dialog’s display, and to reduce logger information to that which concerns packet transmission/reception. Expand restores the full display.

Receivers

The dialog shows icons representing the attached receivers, with their serial numbers. The primary receiver is shown as receiver number 1.

When each receiver receives a data-packet, the signal-strength window within its icon shows a green bar which lengthens in proportion to the signal strength while the data-packet is being received. A small vertical black bar in the signal-strength window shows the strength of the previous signal received. If no further data is received, the black bar moves to the left.

If a receiver is not detected initially, due to a connection or power problem, a warning is displayed on the icon for that receiver until Insight detects it. If preferred, you may remove that receiver’s icon from the display: right-click on the icon and select ‘Remove’.

Loggers

A summary of status and data transmission is shown for each logger in use.

Logger ID -The logger’s serial number – highlighted in blue for the logger which sent the last data-packet to be received.

Battery -Percentage of full charge. For lithium batteries a figure is not shown, but the display will show a warning when the battery charge is low.

Temperature -Temperature of the logger’s thermocouple cold junction (logger’s internal temperature). A warning indicates that the maximum permitted value has been exceeded.

Frequency -The radio frequency currently being used by the system (see above).

Packet ID -Identity number of last data-packet received.

Next Data Due -A countdown, in steps of 1 s, to the time when the next data-packet is expected (according to the sample interval set).

Data Received -The number of valid data-packets received, as a percentage of the total number of data-packets transmitted so far. The reset button next to the percentage figure forces this calculation to restart.

Last Transmission -The scrolling display shows groups of data-packets as they are received. Green packets indicate good data, red packets show invalid data (e.g. with a checksum error). Larger-than-usual gaps between the groups of packets indicate transmissions not received. The time of receipt of the last transmission is shown below the display. You may choose to have the PC beep as each valid data-packet is received.

Real Time Tool – – VIEW > REAL TIME TOOL

Applies to older radio-telemetry systems only. For TM21 system, click here.

For use during a real-time telemetry run, this dialog shows:

The data being gathered by the logger as it is actually being received by the PC, i.e. in real time.
The logger’s changing status as the run progresses.

Reach the Real Time Tool dialog directly by clicking on the toolbar.

Click Expand/Contract to show or hide the full dialog.

Received Packets

The display of received data packets (i.e. sets of data from each of the logger’s probes at a given instant) scrolls to the left, at a rate set by the sample interval, as new data packets are expected. Depending on the situation, the logger may in order to minimize the chance of a failed transmission send each packet more than once (up to nine times), and the status of each copy of each packet received is shown: a tall green bar for a successfully received valid packet, and a shorter red bar for an invalid packet. Receipt of only one valid copy of a packet in each packet group is adequate. If a packet group is not received at all, there is a gap above the packet ID number on the scrolling display.

A counter shows the ID number of the packet last received.

You may choose to have the PC beep as each valid packet is received.

Logger Status

Probe-temperature Indicators -An arrow alongside each one shows whether that probe’s temperature is rising or falling the arrows are paler if the temperatures are stationary.

Internal Logger Temperature -Temperature of the logger’s thermocouple cold junction. If the logger’s internal temperature is nearing cut-off point, the display shows red.

Battery -Current state of charge of the logger’s battery. The display shows red if the charge drops below 16%. NB The display is invalid for lithium batteries.

Memory Used -The proportion of the logger’s memory that has been filled by data.

Real-time Data Collection During Telemetry

During a profile run using hardwired telemetry or radio telemetry, after the first few data packets have been received, the data starts to be displayed in the Graph and Analysis Windows, scrolling in real time as new data arrives. You may change the way the data is displayed with the Axes tab of the Graph Options dialog (from the right-click menu, or from the main menu select View > Graph Options): under Telemetry, specify how much of the recently received data is displayed, and whether you wish to see only a certain temperature (y-axis) range, centered on the latest data.

You may zoom the display as when viewing a paqfile, except that:

Double-clicking on the graph (or selecting Real Time Zoom from the View menu or right-click menu) shows only the most recently received portion of the data on the scrolling graph (see above).
Saved zoom modes are not available.

If the y-axis is not set to be centered (see above), the default y-axis zoom changes as more data is received, in order to accommodate all received data.

To move the graph across the viewing area, hold Shift and drag the mouse pointer.

You may overlay one or more tolerance curves or other paqfiles on the graph to compare with the data as it is being received.

If you wish to open another paqfile and view it in a separate tab while the logger is in listen mode, i.e. while data is being received and viewed in real time, you must first stop real time mode (see below). You may instead, however, open the other paqfile as an overlay while still in real time mode, as above.

You may adjust the oven start position while a real-time run is in progress.

Calculations shown in the Analysis Window for the chosen data analysis mode update continuously as new data is received. As for non-real-time runs, calculations are performed only on the currently zoomed area shown on the graph. However, if the graph is scrolling and showing just the most recently received portion of the results, the analysis calculations will be performed as if on the full zoom view.

Ending Real-time Data Collection

You may wish to end data-collection when the logger is removed from the oven or, by selecting Logger > Stop Real Time Mode, you may end or pause it while a telemetry run is still in progress. Data then continues to be collected by the logger, but it is no longer received in real time by Insight (download from the logger after the run is finished to retrieve the full data). The graphical and numerical data received up to that point remain on screen, available for viewing and analysis, and can be saved as a paqfile.

While the logger is still transmitting, you may resume the collection of transmitted data (select Logger > Logger Listen Mode). After the first few data packets have been received, the data starts to be displayed in the Graph and Analysis Windows. This second bout (and any subsequent bouts) of data-collection can also be ended and saved as a separate paqfile, as above.

If Autosave is enabled (select Tools > Options > General), the data being gathered is automatically saved during a telemetry run. If the PC system fails during the run, the autosaved version of the data is displayed automatically when Insight is next run, and you may then choose to save it as a paqfile.

To stop a real-time run being ended accidentally, you may specify that a password be entered when an attempt is made to close Insight while a run is in progress: select Tools > Options > General.

Although the full data from the profile run should already have been received by Insight, and can thus be saved as described above, it is best practice also to download the data from the logger and to retain that version as well as the transmitted version of data.

When the run is complete, go on to remove the logger from the oven and download the data.

For a hardwired-telemetry run, instead of downloading the data stored in the logger, it should be adequate simply to save the data already received as a new paqfile.

Data Analysis – – RECIPE WIZARD

To change options: in the dialog list, select the first one you wish to change, and click Next.

Or select Skip if you wish to accept the default options for all analyses.

Oven Settings – – RECIPE WIZARD

Variable Line Speed -If the line speed differs between oven zones, select this option and enter the line speed for each zone.

For reference, you may add details of the oven convection level and line width though these do not affect the presentation or analysis of the temperature profile.

When variable line speeds have been set up, overlay of temperature profiles by distance is not possible.

For a rework oven, there are no oven settings to enter.

Oven Start – – RECIPE WIZARD

Temperature Reached -Oven start is set to be the point at which the temperature of any probe rises above a temperature which you specify here.
Automatic (default) -Oven start is determined automatically, based on the point at which the temperature starts to rise rapidly as it enters the oven.
External Trigger -Oven start is relative to an external event, e.g. a Hall-effect switch which is triggered as the product passes a fixed point near the oven entrance.
User -Oven start is set to be a specified distance or time from the start of the data. This allows the user to make an individual judgement about where the oven should be considered to start relative to the point at which data starts to be collected by the logger.

Defined By -Specify here whether distance or time (measured from the start of data collection) will be used to fix the point at which the oven starts.

Oven Zone Temperatures – – RECIPE WIZARD

In the grid, enter the oven zone temperatures – for the lower and upper heaters of each zone – that you wish to use.

If you wish the settings for the upper and lower heaters to be the same, enter the Lower figure, then press cursor down to the next zone – the Upper figure is entered automatically.

The number of oven zones shown, and their names, are taken from the information entered earlier in the wizard, or from the oven file you are using.

Introduction – – RECIPE WIZARD

In order to create a recipe file, the Recipe Setup Wizard takes you through the necessary steps one after the other (click or select Tools > Wizards or File > New > Recipe).

See also Creating a Process File for other ways of setting up a recipe file.

The procedure is largely self-explanatory: enter information as prompted by the wizard, then click Next at the end of each stage.

Select which type of recipe to create:

Basic -A recipe incorporating oven details and oven zone temperatures, and (for reflow ovens only) conveyor line speed, liquidus temperature and the temperature range over which rise time is calculated (soak zone). Default options will be used to setup the other data analysis modes.
Advanced -Additionally, allows the recipe to include a Delta T calculation, definition of oven start, use of a tolerance curve, and setup of data analysis modes.

Reflow Analysis – – RECIPE WIZARD

Entering the liquidus temperature permits analysis of the part of the temperature profile which lies above that value.

To add to the Reflow Results section of the data analysis, you can choose to display the following.

Rise Time to Peak -Time taken for the temperature to rise from the lower specified temperature to the peak value. Enter the lower temperature in the ‘From’ box.

Delta T -Can be calculated in two forms. Select one:

Difference between the peak temperatures of the two probes with the highest and lowest peak temperatures.
Temperature of liquidus minus the temperature of the coolest probe when any other probe first reaches liquidus.

Reflow Analysis (Basic Recipe) – – PROCESS/RECIPE WIZARD

For a conveyorized oven or wave solder oven, enter the oven’s line speed so that the results analysis can display the temperature profile correctly relative to the oven length and to the positions of the oven zones and (if any are defined) profile zones.

Entering the liquidus temperature permits analysis of the part of the temperature profile which lies above that value.

To add to the Reflow Results section of the data analysis, you can choose to set options for the Rise Time the time taken for the temperature of each probe to rise from one specified temperature to another (soak zone). Enter the upper and lower temperatures if you wish to use this option. (Use the Analysis Options dialog to turn the option on or off.)

Default options will be used to setup the other data analysis modes.

Save Recipe – – RECIPE WIZARD

Data for your recipe file has now all been entered and you must give it a filename. The filename will be saved with a .REC extension.

There is a default directory in which recipe files are stored, but you can browse to a directory of your choice.

You can protect the file from unauthorized editing by giving it a password.

Select Oven – – RECIPE WIZARD

The recipe you are creating will be based on an oven, for which you must have an oven file. Select it here. If you do not have an oven file already defined for your oven, you must create one before you can proceed.

The list of oven files shown for selection are those contained in the default oven file directory, but you can also click Browse to locate files which you may have stored elsewhere.

Select Tolerance Curve – – RECIPE WIZARD

Select an existing tolerance curve: a preview is shown of the selected curve.

The list of tolerance curves shown for selection are those contained in the default tolerance curve directory, but you can also click Browse to locate files which you may have stored elsewhere.

Check Profile is Within Tolerance -Select whether to show an alarm if data from one or more probes fall outside the tolerance curve.

If you wish, you may subsequently apply up to four tolerance curves at once, using either the Overlay or Process Details dialogs.

Use Tolerance Curve – – RECIPE WIZARD

Reflow or Wave Solder?

Insight can be used with both reflow and wave-solder ovens and a wave-solder temperature profile can be obtained in two ways:

Wave -Using a standard assembly of logger and thermal barrier, thermocouples are attached to a separate product which passes through the oven, as in reflow profiling.
Wave with Pallet -Thermocouples are fixed to a flat pallet, on which the logger is also mounted, and this passes through the oven; a product, or dummy PCB, may also be part of the pallet.

Temperature profiles resulting from these three oven types require different analyses, and consequently the paqfiles for each also differ: when a reflow paqfile is displayed, the Reflow Results analysis is available in the Analysis Window; when a wave solder paqfile is displayed, the Wave Solder analysis is displayed in its place and analyses differ for the ‘Wave’ and ‘Wave with Pallet’ options.

A process file or an oven, recipe or product file created for one type of oven cannot be used with the other type of oven. When a process file is applied to a paqfile, it sets the type of that paqfile. Thus, if a process file set up for Wave with Pallet is applied to a temperature profile, it will become a Wave with Pallet paqfile and will have the appropriate analysis.

For details of the wave solder hardware and its operation, see the Reflow Tracker General System User Manual.

Insight can be set to automatically name and save the wave-solder data in a paqfile at the end of each profile run.

A temperature profile can be a wave solder paqfile only if it was run with a Datapaq 9000 or Q18 logger.

To carry out a wave-solder profile, run the Wave Solder Wizard.

Reflow Results – – VIEW > ANALYSIS OPTIONS

This analysis mode shows temperature and time data which (apart from Rise Time, see below) are specific to the reflow zone of the temperature profile the region of the profile which lies above the liquidus temperature.

To print the analysis results, select File > Print Options from the main menu.

This mode is available only when a reflow paqfile is displayed (i.e. not with a wave solder paqfile).

To select the data you wish to display, click (or select View > Analysis Options) to display the Analysis Options dialog.

Select here which results will be displayed in the Analysis Window. The results are listed in the grid for each probe separately though you may turn probes off if you choose.

Analysis

All the following data (apart from Rise Time, Rise Time to Peak and Mean Slope to Peak) refer purely to the reflow zone of the profile which lies above the liquidus temperature. Select which results will be displayed in the Analysis Window.

Positive Slope -Maximum positive value for the slope (temperature/time) within the reflow zone for a given probe.
Positive Slope Time –The time after oven start at which the maximum positive slope was recorded.
Rise Time -Time taken for the temperature to rise from the lower to the upper temperature within the specified range. Enter temperatures in the ‘From’ and ‘To’ boxes if you wish to use this option. NB If the upper temperature of the specified range has not been reached, rise time is calculated up to the peak value achieved and is then marked with an asterisk * in the analysis grid.
Rise Time to Peak -Time taken for the temperature to rise from the lower specified temperature to the peak value. Enter the lower temperature in the ‘From’ box.
Mean Slope to Peak -Mean slope (temperature/time) from the first data point visible on screen to the peak of the profile. Zoom the display in the Graph Window to change the area visible and thus define the lowest data point for the calculation.
Time Above Liquidus -Total time which the probe has spent above the liquidus temperature.
Peak Temperature –Highest temperature reading from a given probe.
Delta T -Can be calculated in two forms. Select one:
Difference between the peak temperatures of the two probes with the highest and lowest peak temperatures.
Temperature of liquidus minus the temperature of the coolest probe when any other probe first reaches liquidus.
The analysis grid shows a link between the identified probes marking the lowest ○ and highest ● temperatures.
Delta T is not calculated when one or more paqfiles are overlaid on the current paqfile and ‘Sort by probe’ mode is selected (see below).
Negative Slope -Maximum negative value for the slope (temperature/time) within the reflow zone for a given probe.

Sort By

When multiple files are overlaid on the graph, data from the probes can be grouped to appear in the analysis grid in different ways.

Remove Thermocouple Correction Factors –
CORRECTION FACTORS > REMOVE THERMOCOUPLE CORRECTION FACTORS

Removes thermocouple correction factors from the currently displayed paqfile.

After removal, the graph and analysis data on screen are updated accordingly.

The use of correction factors must be enabled to make the Correction Factors menu and other relevant options visible.

Applying thermocouple correction factors to a paqfile creates an entry in that file’s audit trail.

Recovering the Logger and Downloading Data

Recover the system from the oven as soon as the run is over.

The logger will be hot. Use protective gloves.

Failure to remove the data logger from the hot thermal barrier could damage the logger.

See your system’s User Manual.

Open the thermal barrier. Placing it on a cold surface will increase its rate of cooling. (An additional thermal barrier should be purchased if insufficient time is available to allow it to cool between test runs.)
If data acquisition has to be stopped manually, press and hold the stop button until the red and green status LEDs are on simultaneously. A red LED flashing every 5s indicates data stored in the logger but not yet downloaded to the PC.
Remove the logger from its thermal barrier.
Use the communications lead supplied to connect the logger to a free USB or COM (serial) port on the PC (if using multiple loggers, you must use USB).

To minimize communications problems: a) connect the lead first to the PC and then to the logger; b) if using USB, always use the same USB port the one which was first used to set up communications.

The red LED on the logger should flash five times to confirm that the connection between the communications lead and the logger has been made.

Open the Logger Download dialog (click on the toolbar, or press function key F3, or select Logger > Download from the menu bar) and wait while the data is downloaded to the PC.

You can also download the logger using the Logger Download Wizard (click or select Tools > Wizards).

You can set run alarms to be triggered during a logger download, to warn you of incomplete data recorded during the profile run.

If you see the message Logger stopped due to going over temperature, the logger’s maximum-permitted internal temperature has been exceeded, and it may have suffered damage. The reason for the excessive temperature which may be the result of process operational problems or the use of an inappropriate thermal barrier must be resolved before further profile runs take place; contact Datapaq for advice.

A warning message will also be shown if the logger has stopped recording data due to a discharged battery.

In both cases, data recorded up to that point will have been preserved.

The Select Process dialog then appears in order that you may choose a process file to apply to the results. If the process file and its components have been given names, these are shown when the process file is selected. Click ‘No Process’ if you do not want to apply a process file.

The Apply Correction Factors dialog then appears in order that you may choose thermocouple correction factors to apply to the results.

- Selecting a correction factor file from the lists will display the spool or batch numbers of the thermocouples.

During hardwired telemetry, Insight can apply correction factors to data as it is received, so that the real-time data display is accurate.

The newly downloaded data then appears on screen numerically and graphically. Save the data as a paqfile.

The data from your profile run can now be displayed, printed and analyzed as you wish.

If you have not applied a process file, or if the process file you applied did not specify that the oven start position be adjusted, you may want to adjust that start position now (select Process > Adjust Oven Start). This can be valuable as it permits different paqfiles, i.e. data from different temperature profile runs, to be compared with each other.

You can protect the file from unauthorized editing by giving it a password.

Click Finish to save the file and exit the wizard.

Battery Charge – – LOGGER RESET WIZARD

The type of logger you have connected is shown.

The charge indicator gives both the current percentage of full charge held by the logger battery, and a color-coded report:

	Sufficient charge to perform a run.
	May be enough charge for a run, but battery getting low.
	Insufficient battery charge; recharge immediately.

The battery charge level will not be displayed if the logger is on charge: disconnect the charger to verify battery status.

The display is invalid for lithium batteries.

If in any doubt, abort the procedure by clicking Cancel, and recharge the logger.

Battery life data is available for the Tpaq21 logger.

Click Probe Check to see current temperatures measured on each of the logger’s channels, updated every 5 seconds. This serves as a useful check that thermocouples are working properly. (This feature is not supported by some loggers.)

Connect Communications Lead – – LOGGER RESET WIZARD

The Logger Reset Wizard guides you through the process of readying the logger to receive fresh data before a new profile run.

Any data stored in the logger but not yet analyzed must be downloaded before proceeding, as resetting the logger will permanently erase all data stored in it.

You can also reset the logger using the Logger Reset dialog (click or select Logger > Reset).

For a complete description of running a temperature profile using the Logger Reset and Download dialogs, see Running a Profile.

If you wish to have the option to gather data (via telemetry) from multiple loggers simultaneously, this must first be enabled in the Global Options dialog, and the wizard will then start by allowing you to select between the use of single or multiple loggers.

The procedure is largely self-explanatory: enter information as prompted by the wizard, then click Next at the end of each stage.

After clicking Next in this dialog, the wizard will get reset parameters from the logger.

Reset Completed – – LOGGER RESET WIZARD

The logger has now been reset and is ready for you to start your profile run. The sample interval and trigger mode you have just set are confirmed here. On disconnecting the communications lead, the logger’s red and green status LEDs briefly flash alternately to confirm logger reset.

When the profile run is complete, run the Logger Download Wizard to download the data you have collected.

Select Probes and Sample Interval – – LOGGER RESET WIZARD

Probe 1 must always be one of those selected.

The memory calculator calculates the maximum time for which the logger can collect data, given the sample interval, the number of probes and the logger’s memory size. The time available may be further limited by the level of battery charge.

Select Process File – – LOGGER RESET WIZARD

If you have selected telemetry earlier in the wizard, you may now choose a process file to apply to the results. This will allow you to see the temperature profile in relation to the oven zones as the profile appears on screen during the run.

Click Use No Process File if you do not want to apply a process file.

The list of files shown for selection are those contained in the default process file directory, but you can also click Browse to locate files which you may have stored elsewhere.

If you do not wish to apply a process file at this point, you can still apply one subsequently.

Select Telemetry – – LOGGER RESET WIZARD

If your data logger supports telemetry the capability to transmit data to your computer in real time, i.e. as it is being gathered you will be able to select here which mode to use:

No telemetry -Data is collected by the logger and stored internally until it is downloaded to the PC after the run is completed.
Hard-wired telemetry –Data is transmitted direct to the PC, as it is collected, via the communications lead.
Radio telemetry -Data is transmitted to the PC, as it is collected, via a radio transmitter in the logger and a receiver attached to the PC.

Select Trigger Mode – – LOGGER RESET WIZARD

Select here a trigger mode, i.e. the means which will start the logger recording data.

No Trigger -Data recording starts immediately the reset is complete and the communications lead has been disconnected from the logger (not available for all logger types).
Start Button -After reset, data recording starts when the logger’s green start button is pressed and held for about 1 second.
Date and Time -Data recording starts at a specified date and time. The current date appears by default.
Rising Temperature -Data recording starts when the temperature of any probe (probe no. 1 with MultiPaq21 logger only) rises to the specified value. (If rising or falling temperature trigger mode is set, the logger records data from the time it is disconnected from the PC but, once the trigger temperature has been reached, the logger keeps only a maximum of 60 data points before the trigger point and discards any others. NB Tpaq6 and Tpaq21 loggers do not store this pre-trigger data.)
Falling Temperature -Data recording starts when the temperature of any probe (probe no. 1 with MultiPaq21 logger only) reaches the specified value as it is falling.

After clicking Next in this dialog, the wizard will reset the logger.

Right-click Menu

Right-clicking with the mouse on the graph brings up a shortcut menu of useful key features.

Alarms

Data cells in the Analysis Window can be highlighted automatically, i.e. alarms will be triggered, if their values are outside specified limits. The alarms may be set up to use only a single temperature range, or many temperature ranges, as a trigger.

As a default, only one temperature range is chosen at a time select an alarm range number in the box, then set its alarms:

Alarm Condition -Select the check boxes to set whether or not alarms will operate for various conditions.
Limit -For any alarm condition you set, enter the time limit which will trigger the alarm if it is exceeded or not achieved.
Probe -For any selected alarm condition, click on a probe number to remove it from the list of those whose data may trigger an alarm. Click on the number again to restore it. Right-clicking on a probe number removes all probes except that one; right-click on the number again to restore the other probes. If the logger in use has more than 10 probes, click to open a separate list of probes.

By clicking the Advanced button, you may also:

Click Add and Remove to modify the list of alarm conditions.
Click an entry in the Alarm Condition column to select from a list of various conditions.
Click in the Range column to select the number of the range that is to apply to each condition, or whether exceeding any of the ranges will trigger the alarm.

When the advanced alarms setup is in use, clicking Basic returns the system to use of a single range value.

Rise and Fall Times – – VIEW > ANALYSIS OPTIONS

This analysis mode calculates the rates of heating and cooling for each probe over user-defined temperature ranges, and the time the temperature is within each range.

To print the analysis results, select File > Print Options from the main menu.

To change the time units for slope data, select Tools > Options > Units.

To define the temperature ranges, the data you wish to display, and the alarm criteria, click (or select View > Analysis Options) to display the Analysis Options dialog.

When multiple files are overlaid on the graph, data from the probes can be grouped to appear in the analysis grid in different ways.

Ranges

Define the temperature ranges for which you wish to calculate rates of heating and cooling, time spent within each, etc. Click to add and remove ranges as necessary.

Select which results will be displayed in the Analysis Window. The results are listed in the grid for each probe separately – though you may turn probes off if you choose.

Rise Time -Time taken for the temperature to rise from the lower to the upper value within the range specified below.
Rising Slope -Average rate at which the temperature increases, calculated over the range specified below.
Fall Time -Time taken for the temperature to cool from the upper to the lower value within the range specified below.
Falling Slope -Average rate at which the temperature falls, calculated over the range specified below.
Time Between -Total time which the probe has spent within each specified temperature range (actually calculated as the sum of the Rise Time and the Fall Time, though this will normally be the same thing – unless the probe temperature has varied erratically, e.g. if it was recording air temperature).

If the upper temperature of the specified range has not been reached, times and slopes will be calculated up to the peak value achieved. Such values are marked with an asterisk * in the analysis grid.

Alarms

Data cells in the Analysis Window can be highlighted automatically, i.e. alarms will be triggered, if their values are outside specified limits.

Alarm Colors

Click the Colors tab to select colors for alarm cells and non-alarm cells.

Run Alarms – TOOLS > OPTIONS

You can be warned if the following events are detected during a logger download, reflecting incomplete or invalid data recorded during the profile run.

Logger Stopped Due to Going Over Temperature -Repeated use of the logger with short intervals for cooling can result in a rise in the logger’s internal temperature, leading to logging errors and ultimately to serious damage. This alarm warns if reliable data collection stopped during a run due to excessive internal logger temperature.

The maximum internal logger temperature recorded during a profile run can be seen in the Paqfile Properties dialog (select File > Properties, or graph right-click menu).

Logger Stopped Due to Low Battery -Warns if reliable data collection stopped during a run due to an exhausted logger battery.

Paqfile Contains Invalid Measurements -Warns if any of the downloaded data is invalid.

Alarm Notification

When triggered, an alarm is shown in two ways:

At the bottom of the Analysis Window, an additional Alarms tab appears, giving detailed information on the alarm triggered; this tab also appears when analysis alarms (analysis results falling outside specified limits) or tolerance alarms (for out-of-tolerance profile data) are triggered.
The Alarm Status traffic lights in the Graph Window turn red and the printed report shows in the top right corner (this is also caused by analysis alarms and tolerance alarms).

Running a Profile Overview

A temperature profile can be run by two chief means:

Without telemetry -After the logger and product are sent through the oven, data is downloaded from the logger to the PC to be displayed and analyzed by Insight.
Using telemetry -As the logger gathers data from the product inside the oven, this is transmitted directly to the PC by a fixed connection hardwired telemetry; or by radio transmitter/receiver radio telemetry. The temperature profile can then be watched developing as it happens, i.e. in real time. With suitable hardware, it is possible to use multiple loggers and receivers to gather data and transfer it to the PC.

Using Radio Telemetry

By following this procedure you will use the Logger Reset and Logger Download dialogs to run a temperature profile using radio telemetry. Thus, as the logger gathers data from the product inside the oven, this is transmitted directly to the PC by radio transmitter/receiver. The temperature profile can be watched developing as it happens, i.e. in real time.

After the run is completed, the received data can be saved as a new paqfile. However, as data is also stored internally in the logger during the run, it may be preferable instead to download the data from logger to PC after the run is finished and to save that as the final paqfile. This means there is less chance of the paqfile having missing data points due to losses in transmission.

When running a profile using telemetry, it is possible (with suitable hardware) to use multiple loggers and multiple radio receivers to gather data and transfer it to the PC. See Using Multiple Loggers and Receivers.

If preferred, you may follow this procedure by referring to your dedicated system User Manual and/or your logger User Manual, where there is also more information on setting up the hardware.

If using a single logger for a profile run, you can also use the Logger Reset and Download Wizards to guide you, step-by-step, through the process of running a profile (click or select Tools > Wizards).

Setting Up

For TM21 radio-telemetry system only: Ensure the (primary) receiver is connected to the PC via a USB port, and to its power supply. If Insight has not previously been set up with radio-telemetry receivers, or if the setup has been changed, open the Radio Receivers dialog (click or select View > Radio Receivers) to inform Insight of the receivers attached, and to provide confirmation of correct connection.

Resetting the Logger and Starting the Run

The data logger needs to be reset, as follows, before it can receive fresh data. (If multiple loggers are used for the run, this process is repeated for each logger.)

Any data stored in the logger but not yet analyzed must be downloaded before proceeding, as resetting the logger will permanently erase all data stored in it.

If using the TM21 radio-telemetry system, and if the system’s radio frequency needs to be changed, this is done before the logger is reset, by using the Radio Frequency Wizard. For older radio-telemetry systems, see your hardware manual.

If the logger is fitted with a rechargeable NiMH battery, ensure it is adequately charged. The logger may be on charge during the reset. See your hardware manual for the charging process.
Ensure that a transmitter is fitted to the logger (on the Datapaq 9000, the transmitter module plugs into the end of the logger, and is attached by two screws using the tool provided).
Use the communications lead supplied to connect the logger to a free USB or COM (serial) port on the PC (if using multiple loggers, you must use USB).

To minimize communications problems: a) connect the lead first to the PC and then to the logger; b) if using USB, always use the same USB port the one which was first used to set up communications.

The red LED on the logger should flash five times to confirm that the connection between the communications lead and the logger has been made.

For radio-telemetry systems earlier than the TM21 system, USB cannot be used for connecting the receiver to the PC. Thus, if connecting the logger to a USB port, it is necessary also to have a COM communications lead available to connect the receiver to a COM port on the PC; see stage 6, below.

Open the Logger Reset dialog (click on the toolbar, or press function key F2, or select Logger > Reset from the menu bar) and specify the use of radio telemetry.

Using radio telemetry increases the logger s power consumption and will thus tend to shorten the logger battery s operation time. This effect can be minimized by choosing appropriate reset options, as follows:

Sample Interval -Longer sample intervals reduce power consumption.
Probes Selected -Deselect unused probe channels to prevent transmission of redundant data.
Transmissions (click Advanced Telemetry button) -The system s transmitter can make multiple transmissions ( interleaving ), i.e. it sends each reading a number of times in order to increase reception quality. This can overcome momentary interference such as that caused by the switching of large electrical loads, but it consumes more power. Typically, three transmissions is a good compromise for most industrial processes.

Select other reset options, including trigger mode. Set the radio frequency if required (click the Advanced Telemetry button), though this may also be done before the logger is reset, by using the Radio Frequency Wizard. Note also whether the memory and battery status are adequate for your run (NB The display of battery status is invalid for lithium batteries).

After clicking OK, the logger is reset and a message box confirms the sample interval and trigger mode you have set.
TM21 RADIO-TELEMETRY SYSTEM: Disconnect the communications lead from the logger.
OLDER RADIO-TELEMETRY SYSTEMS: If the logger is connected to the PC s COM port (see stage 3, above), disconnect the communications lead from the logger and connect it to the receiver via the receiver interface cable; if using the PC s USB port for logger connection, disconnect that lead from the logger and connect the receiver to the PC using a COM port communications lead and the receiver interface cable. The power supply (battery charger) lead should be attached to the charger connector on the communications lead.
The logger’s red and green status LEDs then briefly flash alternately to confirm logger reset; click OK.
The Select Process dialog then appears in order that you may choose a process file to apply to the results. If the process file and its components have been given names, these are shown when the process file is selected in the list. Click No Process if you do not want to apply a process file. A process file allows you to see the temperature profile in relation to the oven zones as the profile appears on screen during the run.
If enabled, the Select Correction Factors dialog then appears in order that you may choose a thermocouple correction factor file to apply to the results. Click No Factor if you do not want to apply a correction factor file.
TM21 RADIO-TELEMETRY SYSTEM: If multiple loggers are used for the run, the process above is then repeated for each logger until all are reset.
Plug the thermocouples into the logger’s numbered sockets. If you are using a process file, ensure that the probe/socket numbers on the logger correspond to those used to define probe numbers and locations in that file.
Ensure the sealing surfaces of the thermal barrier are clean and undamaged. Good barrier seals, including those between the barrier and the thermocouple cables, are essential if the logger is to be protected.
If the trigger mode is Start Button, press and hold the logger s start button for about 1 second until the green LED starts to flash at the sample interval.
Put the logger into the barrier, seal it, and place the logger barrier assembly into your process together with your instrumented product or test-piece. For guidance specific to your application, see your system s User Manual.

You may specify that a password is required when an attempt is made to close Insight while a real-time telemetry run is in progress: select Tools > Options > General.

Once new data starts to be received, it is displayed in the Graph and Analysis Windows, scrolling in real time as new data arrives. See Real-time Data Collection During Telemetry.

Running a Profile Without Telemetry

By following this procedure you will use the Logger Reset and Logger Download dialogs to run a temperature profile without telemetry, i.e. data is collected by the logger and stored internally until it is downloaded to the PC after the run is completed and then saved as a new paqfile.

If preferred, you may follow this procedure by referring to your dedicated system User Manual and/or your logger User Manual, where there is also more information on setting up the hardware.

You can also use the Logger Reset and Download Wizards to guide you, step-by-step, through the process of running a profile (click or select Tools > Wizards).

With a wave solder process, you should normally run a temperature profile by using the Wave Solder Wizard.

Resetting the Logger and Starting the Run

The data logger needs to be reset, as follows, before it can receive fresh data.

Any data stored in the logger but not yet analyzed must be downloaded before proceeding, as resetting the logger will permanently erase all data stored in it.

Use the communications lead supplied to connect the logger to a free USB or COM (serial) port on the PC (if using multiple loggers, you must use USB).

To minimize communications problems: a) connect the lead first to the PC and then to the logger; b) if using USB, always use the same USB port the one which was first used to set up communications.

The red LED on the logger should flash five times to confirm that the connection between the communications lead and the logger has been made.

Open the Logger Reset dialog (click on the toolbar, or press function key F2, or select Logger > Reset from the menu bar) and specify your reset options: sample interval, probes selected, telemetry use, multiple events (Tpaq21 logger only click Advanced button) and trigger mode; note also whether the memory and battery status are adequate for your run (NB The display of battery status is invalid for lithium batteries).
After clicking OK, the logger is reset and a message box confirms the sample interval and trigger mode you have set.
Disconnect the communications lead from the logger, and the logger’s status LEDs briefly flash red and green alternately to confirm logger reset.
Plug the thermocouples into the logger’s numbered sockets. If you are using a process file, ensure that the probe/socket numbers on the logger correspond to those used to define probe numbers and locations in that file.
Ensure the sealing surfaces of the thermal barrier are clean and undamaged. Good barrier seals, including those between the barrier and the thermocouple cables, are essential if the logger is to be protected.
If the trigger mode is Start Button, press and hold the logger s start button for about 1 second until the green LED starts to flash at the sample interval.
Put the logger into the barrier, seal it, and place the logger barrier assembly into your process together with your instrumented product or test-piece. For guidance specific to your application, see your system s User Manual.

When the run is complete, go on to remove the logger from the oven and download the data.

Save – – FILE > SAVE

Saves to disk the temperature profile and process data in the paqfile (or SPC file) you are currently editing. The file remains open and you can continue editing it.

Save the currently open paqfile (or SPC file) quickly by clicking on the toolbar.

Save All – – FILE > SAVE ALL

Saves to disk the temperature profile and process data in all the paqfiles you are currently editing. The files remain open and you can continue editing them.

Save all the open paqfiles quickly by clicking on the toolbar.

Save As – FILE > SAVE AS

Paqfile

Allows you to save under a new filename and/or in a new location the temperature profile data in the file you are currently editing. Like your original file, it is saved as a paqfile (*.PAQ). The existing version of the file is closed, and is retained under its original name and without incorporating any changes that might have been made to it since it was last saved. Any process data which are applied to the file at the time you save it are stored with it (i.e. within the paqfile, not in a separate process file). The save dialog opens in the default paqfile directory, though you can browse to any other location to save the file; the default directory can be changed.

Insight can be set to name the paqfile automatically as the data is downloaded from the logger.

If a predicted profile is currently displayed, it cannot be saved as a paqfile. Select Prediction instead (see below).

Process

Saves the process details in the file you are currently editing. The details are saved as a process file (*.PRO). The save dialog opens in the default process file directory, though you can browse to any other location to save the file; the default directory can be changed.

Process file data are saved as a whole, i.e. the component oven, recipe and product data are not stored separately unless you create separate oven, recipe or product files. Thus, if the currently applied data have come from applying oven, recipe or product files which already existed and whose data you have changed since you applied them, those files are not updated.

Prediction

The save dialog opens in the default prediction file directory, though you can browse to any other location; the default directory can be changed.

SPC

Allows you to save under a new filename and/or in a new location the Statistical Process Control file you are currently editing (*.SPC). The save dialog opens in the default paqfile directory, though you can browse to any other location to save the file; the default directory can be changed.

Send – – FILE > SEND

Opens a new email message in your default email program with the currently displayed paqfile attached. In case the email recipient does not have Insight, the email contains a link to download free Paqfile Viewer software with which to view the temperature profile.

To email a PDF of the printed report for the currently displayed paqfile, select File > Print to PDF.

Setup Thermocouple Correction Factors –
CORRECTION FACTORS > SETUP THERMOCOUPLE CORRECTION FACTORS

Starts the Thermocouple Correction Factor Wizard, which will take you through the process of setting up thermocouple correction factors to improve the accuracy of the temperature data recorded during a temperature profile run.

The use of correction factors must be enabled to make the Correction Factors menu and other relevant options visible.

Simple Profile Prediction

By starting with an existing temperature profile, you may alter the oven settings which were used originally to produce it, and immediately see the predicted effect of those adjustments on the profile shape. By a succession of such predictions it is thus possible to arrive at a recipe which will produce a desired target profile. The stages are as follows.

Open the temperature profile (paqfile) to be used as the basis for prediction.

Click or select File > New > Prediction.

The prediction is then performed, and the results are displayed in the main Graph and Analysis Windows.
In the Oven Settings grid, oven zone temperatures can be edited: enter new trial values in the New column, and click to predict and display a revised profile (if lower and upper oven zone temperatures have been set differently in the recipe of the original profile, both are shown); repeat this to modify the shape of the profile as necessary. Predicted results are listed first in the analysis grid, and in the graph window the predicted probe traces are overlaid (in brighter colors) on the original profile. To change the sort order of the probes in the analysis grid, click or .
To save the revised recipe, click to the left of the Oven Settings grid.
To save the predicted profile, click on the main toolbar, or select File > Save, or File > Save As > Prediction; the profile is saved as a prediction file with a .PRE extension.

Prediction files produced by using the Rapid Oven Setup module of Insight (available as an additional purchase) which also carry a .PRE extension are not compatible with this software.

After a simple profile prediction has been performed, some parts of the process file that were applied to the original paqfile will affect the prediction and will therefore not be editable, e.g. adding a zone to an oven would invalidate the prediction and thus is not possible.

You may overlay another paqfile and a tolerance curve on a prediction, e.g. to compare the prediction with an actual profile run.

Slopes – – VIEW > ANALYSIS OPTIONS

This analysis mode calculates the maximum rate of heating and cooling for each probe, the times at which these occurred, and the average rate of change of temperature for each probe. The results can be displayed as the maximum and average slopes over the entire oven, or as separate calculations defining the maximum and average slopes in each oven zone.

To print the analysis results, select File > Print Options from the main menu.

To change the time units for slope data, select Tools > Options > Units.

The rate of change of temperature for specific probes can also be shown on the graph by setting up virtual probes.

To select the data you wish to display, and the alarm criteria, click (or select View > Analysis Options) to display the Analysis Options dialog.

Display Options

Maximum Positive Slope -Greatest positive value for the slope (temperature/time) in the profile data from a given probe. Useful for indicating whether the product is heating up too quickly. (If ‘Over Current Zoom’ is selected for the calculation, and if there is no positive slope within the selected region of the profile, the lowest negative slope value within the selected region is shown.)
Time Reached Positive -The time after oven start at which a given probe’s maximum positive slope was recorded.
Maximum Negative Slope -Greatest negative value for the slope (temperature/time) in the profile data from a given probe. Useful for indicating whether the product is cooling too quickly. (If ‘Over Current Zoom’ is selected for the calculation, and if there is no negative slope within the selected region of the profile, the lowest positive slope value within the selected region is shown.)
Time Reached Negative -The time after the start of the profile run at which a given probe’s maximum negative slope was recorded.
Mean Slope -Mean value of the slopes at all data points in the profile.

Sort By

When multiple files are overlaid on the graph, data from the probes can be grouped to appear in the analysis grid in different ways.

Calculate

Parameters

Specify the basis for calculation of slopes.

Alarms

Data cells in the Analysis Window can be highlighted automatically, i.e. alarms will be triggered, if their values are outside specified limits.

Alarm Colors

Click the Colors tab to select colors for alarm cells and non-alarm cells.

Slopes Parameters and Alarms

The default state for these settings can be set as part of the process or recipe file which is applied to the temperature profile data.

Parameters

Time Over Which Slopes are Calculated -The length of the time periods used to calculate the maximum positive slope and the maximum negative slope at a point in the center of each of those ranges. Thus, the longer the time period the greater the tendency to smooth out the data: this can reduce the influence of minor fluctuations but may mask genuine rapid rates of change.

Alarms

Data cells in the Analysis Window can be highlighted automatically, i.e. alarms will be triggered, if their values are outside specified limits:

Alarm Condition -Select the check boxes to set whether or not alarms will operate for various conditions.
Limit -For any alarm condition you set, enter the value which will trigger the alarm if it is exceeded or not achieved.
Probe -For any selected alarm condition, click on a probe number to remove it from the list of those whose data may trigger an alarm. Click on the number again to restore it. Right-clicking on a probe number removes all probes except that one; right-click on the number again to restore the other probes. If the logger in use has more than 10 probes, click to open a separate list of probes.

Sort By

Only relevant with multiple files overlaid on the graph, or when the paqfile contains data from multiple loggers.

Selects how data from the different probes are grouped as they appear in the analysis grid.

File Groups data for the probes by file (or by logger), i.e. probes 1 to 6 for file 1 (or for logger 1), then probes 1 to 6 for file 2 (or for logger 2), etc.
Probe Groups data for the probes by probe number, i.e. all no. 1 probes from all files (or from all loggers), then all no. 2 probes from all files (or from all loggers), etc.

The sort order can also be changed directly from the Analysis Window by using the (sort by file or by logger) or (sort by probe) buttons.

The setting made as above determines the sort order for the on-screen display only; the setting for the printed report is made separately.

SPC Statistical Process Control

SPC allows easy analysis of the results of your profile runs over time. Thus, by highlighting trends in the performance of your process, potential problems can be identified and dealt with before they occur.

You must first select existing paqfiles on which the SPC analysis will be based, choose which analysis results you will examine, and set a target value and acceptable limits for the results. This is accomplished by running the SPC Setup Wizard (click or select File > New > SPC).

Insight then calculates results and displays them as a new graph in the Graph Window, and as tabulated data in the Analysis Window.

For SPC results to be meaningful, the paqfiles analyzed must be consistent, i.e. they must relate to the same process and must have used the same product with probes in same positions.

To print the analysis results, select File > Print Options from the main menu.

Auto SPC

If you wish to run an SPC analysis regularly on a given process, you may have Insight search automatically for paqfiles which conform to previously specified and flexible criteria: location on disk, date, and associated process or product file. Insight can, for example, automatically locate and run an analysis on all paqfiles from processes which use a given process file and which were created within the last 4 weeks. Running the analysis is thus quick and simple.

The procedure to set this up is as follows.

Run the SPC Setup Wizard, and, In the File Selection stage, select ‘Search for Files’ and specify search criteria.
Click ‘Advanced’, select additional criteria, and check ‘Include future paqfiles which match search criteria’.
Complete the SPC Setup Wizard and save the resulting SPC file.

Alternatively, to use an existing SPC file as a basis, open the file, select SPC > Change Files Used, and select criteria as above.

At any future date, to run an SPC analysis using the criteria you have specified, simply select File > Open > SPC and browse to the SPC file. This will run the analysis, automatically selecting all paqfiles specified by your search criteria including any new matching files created after you set up the SPC file. You may then save the new analysis as an SPC file under a new name (select File > Save As > SPC).

Graphical Display

For each probe, the value of each paqfile’s chosen analysis parameter (on the y-axis) is plotted against the data collection time of the paqfile (on the x-axis) (data points will therefore not necessarily be evenly spaced along the x-axis). Any trend in the results over time can thus be identified and compared with your specified target value and acceptable limits, which are shown on the graph as horizontal lines: the area of the graph outside acceptable limits is colored pink; the area (if any) between the inner limit and outer limit is pale yellow.

Date labels on the x-axis correspond to midnight at the start of that day.

Traces for each probe are displayed in different colors and using different symbols, which can be changed (select View > Graph Options from the main menu, or Options from the right-click menu). Individual probe traces can be turned off if required.

Zoom into your chosen part of the SPC graph by dragging out a rectangle (from top left to bottom right) over the selected area. Return to the normal view by double-clicking on the graph. Zooming does not change the SPC calculations.

You can open more than one SPC analysis at a time (e.g. one for Maximum Temperature and another for Time Above Temperature for the same set of paqfiles). Click the tabs at the top of the Graph Window to select the one you wish to view. The corresponding numerical data will be displayed in the Analysis Window. Individual paqfiles can also be open at the same time.

Analysis Display

The main SPC analysis data is shown on the SPC tab in the Analysis Window.

For each probe, maximum, minimum, mean, and standard deviation are calculated across all the paqfiles’ values of the chosen analysis parameter.

If any individual value for maximum or minimum falls outside the specified limits (outer limits, if two sets of limits are specified), this is shown by x in a colored cell in the Within Spec. column.

Standard deviation gives an indication of the spread of variation within a population or sample from the mean value. A range of 3 standard deviations either side of the mean accounts for 99.74% of the total within that population. Thus, if a process can be controlled sufficiently well that a 3-SD range falls within the outer specified limits, the process should produce defect-free product in 99.74% of its throughput.

Also shown (calculated for each probe and across all probes) are the capability statistics Cp, Cpk, Pp and Ppk. Cpk Ppk Cp Pp

Cpk measures the potential capability of a system to meet a specified standard. In most cases, a value greater than 1.00 is acceptable.

Ppk verifies that the actual performance of a system meets a specified standard. In most cases, a value greater than 1.33 is acceptable.

The minimum acceptable value for Cp is usually not less than 1.

If two sets of limits (inner and outer) are defined, the outer limits are used in the capability calculations.

To hide data columns in the analysis grid, click in the Analysis Window or select View > Analysis Options.

To hide a row of data from an individual probe, click on the probe number.

When a paqfile has overlays, the overlays are ignored in the SPC calculations.

Paqfiles used in an SPC analysis do not all need to have the same number of probes; any combination of probes can be unused in any paqfile.

Files Display

Click the Files tab at the bottom of the Analysis Window to see details of paqfiles used in the analysis. Click on the column headers, to sort the files as required. Changing the listed order does not change the sequence of data on the SPC graph; this is always by date/time.

Saving and Modifying an SPC Analysis

An SPC analysis can be saved as a file with a .SPC file extension. SPC files are stored by default in the same directory as paqfiles. To save the current analysis, select File > Save or File > Save As > SPC.

To open an existing SPC file, select File > Open > SPC.

Insight cannot read trend analysis (.SVT) files produced by Datapaq Surveyor.

An existing SPC analysis can be modified as follows.

Change the files used for the analysis.
Change the analysis results which the SPC examines, or the target value and acceptable limits for the results.

Hover the mouse cursor over a data point on the graph to show a popup with the name of the paqfile corresponding to that point:

To remove a single data point from the SPC analysis quickly, right-click on it on the graph and select Remove File from the menu displayed. This removes the paqfile permanently from the analysis, not simply from the graph.

Select Analysis – – SPC WIZARD

From the Analysis Results list, select the data analysis mode upon which to perform the SPC.

Selecting some analyses will require additional parameters to be entered here. Default values for these are taken from the first paqfile in the list (in the previous wizard stage) but can be changed as necessary.

How to use Statistical Process Control analysis

File Selection – – SPC WIZARD

The SPC Wizard initiates Statistical Process Control on selected data from existing profile runs (paqfiles). To start the wizard, click or select File > New > SPC.

The procedure is largely self-explanatory: enter information as prompted by the wizard, then click Next at the end of each stage.

Specify the paqfiles that you wish to include in the SPC.

To list paqfiles from which you will make a choice, you can make Insight search for them according to criteria you set, or browse to specific files yourself.

Search for files, based on criteria you specify.

1. Specify the folder (and subfolders if required) to be searched. If you require Insight also to examine further folders, this can be done by a subsequent additional search (see below).
2. Specify criteria, e.g. date range, or within the last x days, etc. To include the last 10 paqfiles created, select Number = 10, Units = Files.
3. Click Advanced to select additional criteria which can further restrict the search to paqfiles associated with a given process or product.

- Select All Process Files and Products or specify a process or product by browsing to the appropriate process file or product file, in which case the file-search will be limited to paqfiles which use that process file or product file.
- You may select the use of Auto SPC, i.e. to Include future paqfiles which match search criteria. In this case, the SPC file which the wizard will create will, when opened subsequently, automatically select not only those files currently found by the criteria you are now specifying, but also any new files created subsequently which match the criteria. Running an analysis in future thus becomes quick and simple.
1. Click Search Now to start the search for paqfiles matching the criteria you have selected.

Alternatively, browse to locate specific paqfiles. Use Shift and Ctrl to select multiple files at once. The dialog lists the contents of the default paqfile directory, though you can browse to any other location; the default directory can be changed.

The list must contain at least two paqfiles before SPC can proceed.

For SPC results to be meaningful, the paqfiles analyzed must be consistent, i.e. they must relate to the same process and must have used the same product with probes in same positions.

Limits – – SPC WIZARD

Ensure that the limits you specify are correct for your process; if this is not the case, the capability calculations will be invalid.

Text in the dialog explains how the limits will be used in the capability calculations.

Check Save these limits for next time to have the limits you set here become your default until they are changed again.

SPC has now been set up. Click Finish to start the calculation and display the results.

How to use Statistical Process Control analysis

Startup Screen

The startup screen guides you directly to the main features of the software. Most of these operations are carried out using wizards, which lead you through the various processes step-by-step.

Once you are more familiar with the main tasks you wish to perform, you may wish not to see this screen automatically on start-up: uncheck Display on Startup.

You may still see the startup screen at any time by clicking on the toolbar or by selecting Wizards from the graph right-click menu or Tools > Wizards on the main menu bar.

Status Bar – VIEW > STATUS BAR

Check or uncheck to make visible the status bar at the bottom of the Insight window. This shows:

A brief description of the toolbar buttons when the cursor is hovering over one.
Time and temperature at the cursor position as the cursor is moved over the graph.
Whether the keyboard caps lock, num lock and scroll lock are on.

Stop Real Time Mode – LOGGER > STOP REAL TIME MODE

Stops the collection of data being transmitted while a telemetry run is in progress. Data continues to be collected by the logger, but it is no longer received in real time by Insight (download from the logger after the run is finished to retrieve the full data). The graphical and numerical data received up to that point remain on screen, available for viewing and analysis.

If you wish to keep the data already received, save it as a paqfile.

Use Logger Listen Mode to re-start real-time data collection while the same telemetry run is in progress.

Number of Probes –
THERMOCOUPLE CORRECTION FACTOR WIZARD

In order to create a thermocouple correction factor file, the Thermocouple Correction Factor Wizard takes you through the necessary steps one after the other.

The use of correction factors must be enabled to make the Correction Factors menu and other relevant options visible.

To run the wizard, select:

File > New > Thermocouple Correction Factors, or
Correction Factors > Setup Thermocouple Correction Factors.

The procedure is largely self-explanatory: enter information as prompted by the wizard, then click Next at the end of each stage.

Specify the number of thermocouple probes you will be using.

Same Spool or Different Spools –
THERMOCOUPLE CORRECTION FACTOR WIZARD

If your thermocouples are made of wire from different spools, they will have different correction factors. Specify this here.

If all thermocouples are from the same spool, after clicking Next you will proceed to enter calibration data.
If thermocouples are from different spools, after clicking Next you will specify which thermocouples come from which spool.

Save Correction Factors –
THERMOCOUPLE CORRECTION FACTOR WIZARD

Data for your thermocouple correction factor file has now all been entered and you must give it a filename. The filename will be saved with a .CAL extension.

Correction factor files are stored by default in the default paqfile directory, but you can browse to a directory of your choice.

Select Thermocouples –
THERMOCOUPLE CORRECTION FACTOR WIZARD

Select all the thermocouples which were made from any one spool of wire (if all were made from the same spool, click Back to return to the previous wizard stage).

If any thermocouples have already been set up, the spool number from which they came is shown.

The wizard will then prompt you to enter calibration data for the current spool and the process will be repeated for any remaining thermocouples made from different spools.

Set Thermocouple Correction Factors –
THERMOCOUPLE CORRECTION FACTOR WIZARD

Enter calibration data for your thermocouples. The data you enter here will apply to all the thermocouples listed at the head of this wizard dialog.

Click the Add button until you have specified the total number of set temperature calibration points for the spool from which these thermocouples were made.

Then, for each calibration point, enter the temperature readings obtained from a thermocouple made from the start and the end of the spool. Corrections are calculated automatically as you enter the readings.

To remove a calibration point, click on it in the grid and then click Remove.

To view or edit the data you enter here, after creating the thermocouple correction factor file, open it with File > Open > Thermocouple Correction Factors.

If any thermocouples remain to be set up, after clicking Next the wizard will prompt you to enter further data.

Time at Temperature – – VIEW > ANALYSIS OPTIONS

This analysis mode calculates the time taken to reach user-selected temperatures and the time spent above or below each of these threshold temperatures.

To print the analysis results, select File > Print Options from the main menu.

To define the thresholds, and the alarm criteria, click (or select View > Analysis Options) to display the Analysis Options dialog.

Sort by

When multiple files are overlaid on the graph, data from the probes can be grouped to appear in the analysis grid in different ways.

Calculate

Thresholds

Define the threshold temperatures you wish to use. Specify also whether you wish to display times spent above or below these thresholds, and times taken to reach the thresholds.

In the Analysis Window the results are listed in the grid for each probe separately though you may turn probes off if you choose. The analysis can be applied to the whole profile or to only a specific part of it (see ‘Calculate’, above).

Alarms

Data cells in the Analysis Window can be highlighted automatically, i.e. alarms will be triggered, if their values are outside specified limits.

Alarm colors

Click the Colors tab to select colors for alarm cells and non-alarm cells.

Time at Temperature Thresholds and Alarms

The default state for these settings can be set as part of the process or recipe file which is applied to the temperature profile data.

Thresholds

Define the threshold temperatures you wish to use. In the Analysis Options dialog, you can select also whether or not times spent above or below these thresholds, and times taken to reach the thresholds, are to be displayed in the Analysis Window.

Alarms

Data cells in the Analysis Window can be highlighted automatically, i.e. alarms will be triggered, if their values are outside specified limits. The alarms may be set up to use only a single threshold value, or many threshold values, as a trigger.

As a default, only one threshold value is chosen at a time select an alarm threshold number in the box, then set its alarms:

Alarm Condition -Select the check boxes to set whether or not alarms will operate for various conditions.
Limit -For any alarm condition you set, enter the value which will trigger the alarm if it is exceeded or not achieved.
Probe -For any selected alarm condition, click on a probe number to remove it from the list of those whose data may trigger an alarm. Click on the number again to restore it. Right-clicking on a probe number removes all probes except that one; right-click on the number again to restore the other probes. If the logger in use has more than 10 probes, click to open a separate list of probes.
Real Time -(For alarm condition ‘Time above threshold is greater than’ only.) If checked, and if that alarm condition is selected and is triggered during a real-time telemetry run, a red alarm screen will be shown and must be acknowledged by the operator. For each such alarm, an entry will appear in the audit trail.

By clicking the Advanced button, you may also:

Click Add and Remove to modify the list of alarm conditions.
Click an entry in the Alarm Condition column to select from a list of various conditions.
Click in the Threshold column to select the number of the threshold that is to apply to each condition, or whether exceeding any of the thresholds will trigger the alarm.

When the advanced alarms setup is in use, clicking Basic returns the system to use of a single threshold value.

Edit Profile – – TOLERANCE CURVE WIZARD

This stage of the wizard has two forms, depending on whether you are basing the tolerance curve on data for an existing paqfile, or on a solder paste specification.

Defining Tolerance Curve from an Existing File

To re-shape the curves, click on a data point and drag the mouse pointer along the new path. Successive data points will then follow the track of the mouse pointer. To ensure you move a single data point only, hold down Control as you drag it. You may change the shape of the initial profile as well as that of the tolerance curves themselves. Cursor position is shown by time/temperature coordinates below the graph to the right.

If you have altered the initial profile and have opted to use a single probe trace on which to base your tolerance curve, clicking Reset Bands automatically repositions the (inner and outer) bands so that they have the offsets specified earlier in the wizard.

Click Clipboard to export the tolerance curve data to the clipboard and edit it, e.g. in a spreadsheet application. The revised data can then be used to create a new tolerance curve by importing it as a .CSV or text file.

Any region of the graph can be zoomed by dragging out a rectangle (from top left to bottom right) over the selected area. Return to normal view by double-clicking on the graph (or by dragging a rectangle from bottom right to top left). Click Reset Zoom to return to the full-zoom view.

To move the graph (pan) across the viewing area, hold Shift and drag the mouse pointer. This is particularly useful when the graph is zoomed.

The liquidus temperature is shown on the graph. For each of the curves, the time spent above liquidus and the peak temperature are given.

Defining Tolerance Curve from a Paste Specification

Insight creates a default tolerance curve based upon the JEDEC standard curve, with the duration specified in the first stage of the wizard. A tolerance curve with a single envelope of acceptability will be generated (i.e. an outer band only, not inner and outer bands).

Start by entering data from your solder paste’s specification into the data grid. As you do this, dependent values within the grid, and the boundaries shown on the graph, will change to reflect the new data.

The following rules are applied when editing data in the grid:

Editing slopes durations are changed, but temperatures are not affected.
Editing durations slopes are changed, but temperatures are not affected.
Editing temperatures slopes are changed, but durations are not affected.

Move data-points (and thus re-define regions) by dragging the data-points on the graph.

The outer boundary of the tolerance curve is initially defined by six regions. To select a region, click near it; the selected region is indicated by a rectangle on the graph stretching between its start and end data-points. To add data-points (and thus regions), select the region within which the new point should fall, and click Split Region. Similarly you may Delete Region.

Zoom to any region of the graph by dragging out a rectangle (from top left to bottom right) over the selected area. To return to normal view, double-click on the graph or click Reset Zoom.

To move the graph (pan) across the viewing area, hold Shift and drag the mouse pointer. This is particularly useful when the graph is zoomed.

Liquidus Temperature – – TOLERANCE CURVE WIZARD

Enter the liquidus temperature so that this can be displayed with the tolerance curve for guidance.

Save Tolerance Curve – – TOLERANCE CURVE WIZARD

Your tolerance curve has now been created and you must give it a filename. The filename will be saved with a .TOL extension.

There is a default directory in which tolerance curves are stored, but you can browse to a directory of your choice.

After clicking ‘Finish’ you will have created your tolerance curve. To apply it, see Creating and Using Tolerance Curves.

Select Method – – TOLERANCE CURVE WIZARD

A tolerance curve provides an envelope of acceptability against which to compare the temperature profile from a product’s run through the oven. It can be created by basing it on:

An existing temperature profile (paqfile) whether held on disk or currently displayed on screen.
A solder paste specification.
A .CSV (spreadsheet) or text file.

Importing as a .CSV or text file is particularly useful if you have previously exported tolerance curve data in order to edit it, e.g. in a spreadsheet application. The revised data can then be used to create a new tolerance curve.

If basing the curve on an existing paqfile, choose a high enough number of data points to give you a sufficiently smooth curve. Too high a number of data points may track an existing profile too closely and produce a curve which is less smooth and is more time-consuming to create or edit.

If basing the curve on a solder paste specification, enter a duration for it. Otherwise, the duration will follow the paqfile on which you base the curve; any data before the oven start position is not used.

Select Paqfile – – TOLERANCE CURVE WIZARD

Select the paqfile on which your target profile will be based. Choose either:

The paqfile currently displayed on screen, or
One which you will load from disk; click Browse to locate it (you can change the default paqfile directory if you wish).

If importing a .CSV or text file, the wizard then proceeds directly to the Edit Profile stage.

Select Paqfile Usage – – TOLERANCE CURVE WIZARD

When basing your tolerance curve on an existing paqfile, choose the way in which the paqfile will be used:

Maximum Difference -This method constructs an envelope based on the highest and lowest probe values at each data point on the curve. You can choose which probe traces (at least two) to include in this. If there are too many probes to display all at once in the dialog, a More button will appear; click this to see a full selectable list of probes.
Selected Probe -Choose the trace from a single probe to use as the initial profile around which the tolerance curve will be based.

Tolerance Bands – – TOLERANCE CURVE WIZARD

This stage of the wizard is not shown if basing the tolerance curve on a solder paste specification.

If you have opted to use a single probe trace on which to base your tolerance curve, you can choose either to create a curve with a single envelope of acceptability an outer band only within which your profile data should fit, or the envelope can have outer and inner bands. Select which you want, and define the upper and lower offsets that each will have from the initial profile.

To produce a reference curve with no tolerance envelope (i.e. an ideal curve), select Outer Band Only and set offsets to 0.

After you have created your tolerance curve and applied it to a temperature profile, you can:

Choose whether or not to show an alarm if the profile contains out-of-tolerance data.
Use the Graph Options dialog to choose colors for the tolerance curves and whether or not to display the inner and/or outer bands and the curve’s initial profile.

Toolbar – VIEW > TOOLBAR

Check or uncheck to make visible the toolbar (below the main menu bar) for single-click access to various key functions.

Units – TOOLS > OPTIONS

Select the units of temperature, distance and time that you wish to use for entering data and in which your results and analyses will be displayed.

Time is shown in one of the available combinations of hours (hh), minutes (mm), seconds (ss) and tenths of a second (tt). If time of day format is selected, times will be shown in the Graph and Analysis Windows as actual times of day.

Slope Time Units -Select seconds, minutes or hours as the time units to be used for slope measurements.

Choose units for distance and time appropriate to the length of your oven and the time taken by the process.

Custom Units

For loggers having probes which register voltage or current directly, you may click Custom Units to open the Custom Units dialog and specify the units in which their measurements will be displayed on a scale on the graph’s right-hand y-axis.

Different custom units can be set up for voltage and current:

Under Probe Type, select either voltage or current.
Check Use Custom Units, and enter selections. Text entered under ‘Name’ and ‘Unit’ will be displayed on the graph’s right-hand y-axis. The minimum and maximum values entered here will define the extent of the right-hand y-axis scale.

Insight assumes a linear relationship between voltage/current and the custom units. The minimum-specified custom-unit value maps onto the minimum voltage/current, and the maximum-specified custom-unit value maps onto the maximum voltage/current.

Insight remembers between sessions the custom units which were last set up, and these are the default for any new paqfiles containing voltage or current data. Custom units applied to an individual paqfile are stored in the paqfile, so that these are maintained and displayed even if different global settings for custom units are in place.

Edit an individual paqfile s custom units in the Graph Options dialog (from the graph right-click menu, or from the main menu select View > Graph Options): click the Axes tab, then click ‘Expand’.

Using Hardwired Telemetry

In addition to the standard off-line analysis, real-time analysis by hardwired telemetry is possible with many models of Datapaq logger (see your dedicated hardware manual).

Thus, with thermocouples trailing from the oven and attached to the logger outside the oven, data being gathered by the logger is transmitted via the communications lead directly to the PC, and the temperature profile can be watched developing as data is received, i.e. in real time.

Running a profile in real time is performed in essentially the same way as a normal (non-telemetry) run, except:

In the Reset dialog, select Hardwired Telemetry.
After clicking OK in the Reset dialog:
- The Select Process dialog then appears in order that you may choose a process file to apply to the results. If the process file and its components have been given names, these are shown when the process file is selected in the list. Click No Process if you do not want to apply a process file. A process file allows you to see the temperature profile in relation to the oven zones as the profile appears on screen during the run.
- If enabled, the Apply Correction Factors dialog then appears in order that you may choose a thermocouple correction factor file to apply to the results. Click No Factor if you do not want to apply a correction factor file.
- Instead of disconnecting the communications lead after resetting the logger, leave it attached to the logger and PC.

Once new data starts to be received, it is displayed in the Graph and Analysis Windows, scrolling in real time as new data arrives. See Real-time Data Collection During Telemetry.

When the run is complete, ensure that data received by Insight has been saved as a paqfile. If you wish, you may download the data held in the logger, though it should normally be adequate simply to save, as a new paqfile, the data already received.

Using Memos

Memos allow you to annotate your results directly on the graph. There are two types:

Box memo -Text is permanently visible in a box, with an arrow showing the point of interest on the graph.
Vertical-line memo -A position on the time/distance axis of the graph is marked by a thick, colored, vertical line; the memo text appears when the cursor is hovered over this.

Creating Memos

Right-click on the graph at the point where you wish the memo to appear.
Select Add Memo from the popup menu.
Enter your text.
Select a color.
Select vertical-line memo if you wish it to be one.
Click OK.

The Add Memo dialog is also available by selecting Edit > Memos and clicking Add. The memo you create will then appear on the graph in the middle of the current view.

In order to mark specific events as they occur during a real-time telemetry run, memos can be inserted at any point while the run is actually in progress:

As the event occurs, click the event-marker button on the main toolbar or select Edit > Add Event Marker.
The Add Memo dialog appears, with vertical-line memo selected as default.
Enter any text for the memo, select a color for the line and click OK.
The memo appears on the graph marking the point at which the event-marker button was clicked.

Editing Memos

To reach the Edit Memo dialog, either:

Right-click on the memo on the graph, and select ‘Edit’, or
On the main menu select Edit > Memos, then

Click in the text of the memo you wish to change, and click ‘Edit’ (or double-click on the text).

Edit the text, or change the background color (box memo only), or change the memo to/from a vertical-line memo.
Click OK.

Moving Memos

Box memo -Move the memo’s pointer by holding Control as you click on its arrowhead and drag it to a new position; the box and pointer move together. If necessary, then move the box alone by holding Control as you click within it and drag; the arrowhead stays fixed in its new position.

Vertical-line memo -Move the marker line by holding Control as you click on and drag the line.

Removing Memos

Either:

Right-click on the memo on the graph, and select ‘Remove’, or
On the main menu select Edit > Memos, then

Click in the text of the memo you wish to remove, and click ‘Remove’.

Hiding Memos

On the Profile Options tab of the Graph Options dialog (from View menu or right-click menu), uncheck Memos Visible.

Printing

When the graph is printed, box memos appear as they do on screen. Vertical-line memos appear with their text displayed.

Using Multiple Loggers and Receivers

When running a profile using telemetry, it is possible to use multiple loggers and (with radio telemetry) multiple receivers to gather data and transfer it to the PC.

Use of multiple loggers and/or multiple receivers in radio telemetry is possible only with the TM21 telemetry system.

When using multiple loggers and/or multiple receivers with the TM21 radio-telemetry system, the whole system uses a single radio frequency. The TM21 system is supplied with transmitter(s) and receiver(s) configured so that they can communicate, but the system’s radio frequency can be changed, if necessary, using the Radio Frequency Wizard: click or select View > Radio Receivers > Radio Frequency Wizard.

Multiple Loggers

Using multiple loggers permits data to be gathered from a greater number of thermocouple channels than can be achieved with a single logger.

Multiple loggers used with radio-telemetry may be housed in the same or in separate thermal barriers.

Data from multiple loggers used in a single profile run is stored in a single paqfile, The whole of the data contained in that paqfile is then displayed and analyzed just as for a single-logger paqfile.

The floating logger toolbar controls the display of data from each logger, and allows data from any one logger to be saved as a separate paqfile. The logger number shown in the logger toolbar allows duplicate probe numbers from the multiple loggers to be separately identified in the Analysis Window and probe toolbar, and in the probe key to the right of the graph.

The sort order of the duplicate probe numbers in the Analysis Window is changed by the and buttons.

While a telemetry run is in progress, the Real Time Tool dialog gives a summary of status and data transmission for each logger in use.

To use multiple loggers with hardwired telemetry, all loggers must be connected to the PC via USB (not by COM port).

When using the Furnace Surveying module of Insight, the use of multiple loggers is handled entirely by the Temperature Uniformity Survey Wizard which is available within that module.

Multiple Receivers

The use of multiple radio receivers is of value chiefly in applications where the secure transmission and reception of radio-telemetry data requires receivers to be sited at various widely separated points to pick up data from a logger moving through the heat-treatment process.

In the TM21 radio-telemetry system, a (single) primary receiver is attached to the PC. If additional secondary receivers are used, these are daisy-chained to the primary receiver (see the TM21 Radio-telemetry System User Manual).

If Insight has not previously been set up with radio-telemetry receivers, or if the setup has been changed, open the Radio Receivers dialog (click or select View > Radio Receivers) to inform Insight of the receivers attached; the dialog also provides confirmation of correct connection.

Data received by Insight from multiple radio receivers is displayed and analyzed just as if only a single receiver were in use. However, while a telemetry run is in progress you can use the Real Time Tool dialog to obtain confirmation in real time of the data being received by individual receivers.

Using Slope Markers

Slope Markers allow you to annotate your results directly on the graph by indicating desirable or actual slopes at different parts of the temperature profile.

The marker consists of an arrow, whose angle can be changed; the slope of the arrow is shown automatically next to it.

Creating Slope Markers

Right-click on the graph at the point where you wish the marker to appear.
Select Add Slope Marker from the popup menu.

Altering Slope Markers

Hold Control as you click and drag the marker’s arrowhead to change the angle of the marker.

Hold Control as you click and drag the other end of the marker to move the whole marker.

Removing Slope Markers

Right-click on the marker on the graph, and select ‘Remove’.

Utilities – FILE > UTILITIES

Merge Paqfiles

Runs the Merge Wizard which combines temperature profiles from any number of paqfiles to form a single composite file.

Paqfile Extract

Creates a new paqfile from the data contained within the length of the y-axis shown by the current zoom. The new filename will be saved with a .PAQ extension. The default directory in which paqfiles are stored is shown, but you can browse to a directory of your choice.

Load this Paqfile -If checked, the newly defined paqfile will be displayed after clicking OK.

Import from File

Data from other sources can be imported and displayed as a paqfile. The data file must be a text file, having one of the following formats:

.EXP -Export file generated from a paqfile in Datapaq Tracker v.4. The file will contain a header as described below.
.TXT -Simple text file.
.CSV -Comma Separated Value format, as exported from a spreadsheet.

To allow it to be displayed as a paqfile, the data file must start with a file header. Click Print Example to see how this must be laid out. The example contains all the possible recognized entries for a file header, and, of these, the minimum required are:

#interval Sample interval, i.e. time between each set (sample) of data points.
#number of channels Number of probes from which data are included.
#paqfile start time Time at which the profile was run.
#paqfile start date Date on which the profile was run.
#start time Sets the start of elapsed time, i.e. can be negative if oven start is to fall after the start of data collection.

Any other entries in the header must be valid, i.e. must be among those in the Print Example.

This is then sufficient to define the time of each set of data points and, if preferred, times may be omitted from the data point list.

The logger ID, if included in the header, must be prefixed by # if it is a Datapaq logger, thus:
#logger = #1234

For data from a non-Datapaq logger, there must be no #, thus:
#logger = 3456

To export data from an existing paqfile, use Copy to Clipboard.

Import from Clipboard

Opens the Clipboard Paste Wizard, which guides you through the process of selecting data in a spreadsheet application and importing it to a new or existing paqfile.

If imported measurements are merged with an existing paqfile:

The new data is assigned to additional thermocouple numbers. For example, if merging with a paqfile with probes numbered 1 to 6, the imported probes would be numbered from 7 onwards.
The paqfile will have entries added to its audit trail to indicate that some of the probes were imported.
You may need to adjust probe alignment for the imported measurements if they do not correspond with the existing data’s time axis; select Process > Adjust Probe Alignment.

View Data – – VIEW > ANALYSIS OPTIONS

This analysis mode shows the raw time and temperature data for each probe, as gathered by the logger.

To print the analysis results, select File > Print Options from the main menu.

The probe profile which is currently selected is thickened on the graph and on the Probe Key to the right of the graph. To select a different probe profile, click on it on the graph.

Drag the cursor bar across the graph to obtain precise time and temperature data for a specific probe. These are shown numerically:

On the graph above the top of the cursor bar.
In the data grid in the Analysis Window. The grid scrolls as the cursor is moved, with the top line of data in the grid corresponding to the current cursor position.

Similarly, scrolling the data table moves the cursor across the graph.

Zooming into a region of the graph (drag out a rectangle from top left to bottom right) re-locates the cursor to the center of the zoomed region. Return to the normal view by double-clicking on the graph.

Values at the start of the data may be negative. This is because the oven start falls after the logger started recording data.

To select how the data will be displayed in the Analysis Window, click (or select View > Analysis Options) to display the Analysis Options dialog.

When the view of some probes is disabled, you may click (left of the data grid) to hide the data columns for those probes. Click to show those empty data columns again.

Display Options

Show Distances -Uncheck to remove the Distance column from the display.
Highlight Invalid Data -When checked, cells in the grid which contain invalid data will be highlighted.
Show Zones -When checked, the data grid shows a numbered marker at the start of each oven zone and highlights the corresponding data row (this is displayed whether or not you have selected Oven Zones Visible on the graph).

Sort by

When multiple files are overlaid on the graph, data from the probes can be grouped to appear in the analysis grid in different ways.

File –Shows data for one file at a time. Use the box above the analysis grid to select which file’s data are displayed.
Probe –Groups data for the probes by probe number, i.e. all no. 1 probes from all files, then all no. 2 probes from all files, etc.

The sort order can also be changed directly from the Analysis Window by clicking the (sort by file) or (sort by probe) buttons.

Colors

Click the Colors tab to select colors for normal cells and for invalid data cells.

Virtual Probes – EDIT > VIRTUAL PROBES

A virtual probe is a probe trace which has been calculated from measured thermocouple values. In the Virtual Probes dialog, select checkboxes as necessary if you wish them to be shown on the graph. To de-select the values for one or more probes, i.e. to prevent them being included in the calculation of the probe trace, click on the numbered probe buttons in the dialog.

Mean -One or more virtual probe traces can be shown on the graph, each representing the mean of the values measured by the probes selected. Click Add to create any additional virtual probes, as required. Values calculated from this virtual probe will be included in the Analysis Window according to the analysis option selected.
First Derivative -For each probe selected, a virtual probe trace will be generated which represents the first derivative (slope) of that probe. The scale is shown by the right-hand y-axis of the graph. Because the y-axis values of these virtual probes do not represent units of temperature, numerical values are shown in the Analysis Window on the View Data tab but not in any other analysis mode.
Temperature Difference -A virtual probe trace will be shown on the graph representing the difference between highest and lowest temperature values of the selected probes at each point in the profile.

The Virtual Probes dialog is also available from the graph right-click menu.

The rate of change of temperature for specific probes can also be analyzed using the Slopes analysis mode.

Virtual probes cannot be created from probe data in an overlaid paqfile. If a paqfile which already contains virtual probes is used as an overlay, those virtual probes will not be shown.

Wave Solder – – VIEW > ANALYSIS OPTIONS

This analysis mode shows temperature and time data which are specific to use of the wave solder process.

This mode is available only when a wave solder paqfile is displayed (i.e. not with a reflow paqfile). Wave solder paqfiles are of either the ‘Wave’ or ‘Wave with Pallet’ type, and analyses for these differ from each other in some respects (see below).

To print the analysis results, select File > Print Options from the main menu.

To select the data you wish to display, and the alarm criteria, click (or select View > Analysis Options) to display the Analysis Options dialog.

Display Options

Select here which results will be displayed in the Analysis Window. The results are listed in the grid for each probe separately – though you may turn probes off if you choose.

Pre-Heat -Select to show data for the section of the oven in which the PCB is heated before it reaches the solder wave.

Insight calculates the end of the pre-heat zone automatically, based on the shape of the temperature profile. In the Graph Window this is marked by a vertical line labelled Pre-Heat End.

To redefine the end of the pre-heat zone, hold Control as you click on the marker and drag it to a new position (it may be useful to zoom the graph before you do this). The data in the Analysis Window is then automatically recalculated to reflect the change.

Slope -Slope of the profile (temperature/time) in the pre-heat phase of the profile data. Useful for indicating whether the product is heating up too quickly. Values are given for the maximum slope (greatest positive value) and for the mean slope (mean rate of rise over the whole pre-heat phase).
Peak Temperature -Highest temperature reached during the pre-heat phase.
Delta T (‘Wave with Pallet’ paqfile only) -Difference between a PCB probe’s peak temperature when it hits the solder wave and the temperature at the end of the pre-heat phase.
Rise Time -Time taken for the temperature to rise from the lower to the upper value within the specified range.
PCB Peak Temperature -Highest temperature reached by the PCB itself.
Main Wave -Select to show data for the main solder wave: for ‘Wave’, details available are contact time and Delta T; for ‘Wave with Pallet’, details available are contact time, contact length and parallelism (see below).

Chip Wave -Select to show data for the chip wave. This is only shown if the presence of a chip wave is detected.
Contact Time -The time for which a given carrier thermocouple is in contact with the solder wave. If Calculate Contact Time as a Time Above Temperature is also selected (‘Wave’ paqfile only), contact time is calculated as the time spent above a temperature which you specify here.
Contact Length (‘Wave with Pallet’ paqfile only) -The length over which the solder wave makes contact with a given carrier thermocouple.
Parallelism (‘Wave with Pallet’ paqfile only) -Select to show the extent to which the solder wave is not precisely at right angles to the path of the PCB. If Calculate Parallelism using Contact Time is also selected, parallelism is calculated as the time difference between the left and right thermocouples contacting the solder wave; if not selected, parallelism is calculated as the time difference between the left and right edges of the logger carrier hitting the wave. In both cases, zero difference indicates perfect parallelism.
Delta T (‘Wave’ paqfile only) -Difference between a PCB probe’s peak temperature when it hits the solder wave and the temperature at the end of the pre-heat phase.
Line Speed (‘Wave with Pallet’ paqfile only) -The rate at which the PCB moves through the oven.

If using a non-Datapaq pallet, you must specify in the wizard the distance by which probe 5 is behind probes 4 and 6.

Sort By

When multiple files are overlaid on the graph, data from the probes can be grouped to appear in the analysis grid in different ways.

Parameters

Specify the basis for calculation of slope and rise time.

Probes for Wave Analysis

(For ‘Wave’ paqfiles only.) Show which thermocouple probes are on the underside of the PCB and make contact with the solder wave. Click on the numbered buttons to de-select probes which do not touch the wave.

If probes are selected wrongly here, the analysis will be incorrect.

Alarms

Data cells in the Analysis Window can be highlighted automatically, i.e. alarms will be triggered, if their values are outside specified limits.

Alarm Colors

Click the Colors tab to select colors for alarm cells and non-alarm cells.

Wave Solder Parameters and Alarms

The default state for these settings can be set as part of the process or recipe file which is applied to the temperature profile data.

Time Over Which Slopes are Calculated -The time period used to calculate the slope at a point in the center of that range. Thus, the higher the figure the greater the tendency to smooth out the data: this can reduce the influence of minor fluctuations but may mask genuine rapid rates of change.
Calculate Rise Time -Select whether to display the time taken for the temperature to rise from a lower value to an upper value, both of which you can specify here.

Alarms

Alarm Condition -Select the check boxes to set whether or not alarms will operate for various conditions.
Limit –For any alarm you set, enter the value which will trigger it.
Probe -For any selected alarm condition, click on a probe number to remove it from the list of those whose data may trigger an alarm. Click on the number again to restore it. Right-clicking on a probe number removes all probes except that one; right-click on the number again to restore the other probes.

Battery Charge – – WAVE SOLDER WIZARD

The charge indicator gives both the current percentage of full charge held by the logger battery, and a color-coded report:

	Sufficient charge to perform a run.
	May be enough charge for a run, but battery getting low.
	Insufficient battery charge; recharge immediately.

The battery charge level will not be displayed if the logger is on charge: disconnect the charger to verify battery status.

If in any doubt, abort the procedure by clicking Cancel, and recharge the logger.

After clicking Next in this dialog:

If running a ‘Wave with Pallet’ profile, the wizard will reset the logger.
If running a ‘Wave’ profile, the wizard will ask for confirmation of the probe numbers which are positioned under the PCB to measure the wave.

Connect Communications Lead – – WAVE SOLDER WIZARD

Use the communications lead supplied to connect the data logger to a free USB or COM (serial) port on the PC (to minimize communications problems, connect the lead first to the PC and then to the logger). The red LED on the logger should flash five times to confirm that the cable logger connection has been made.

After clicking Next in this dialog, the wizard will get reset parameters from the logger.

Position Probes – – WAVE SOLDER WIZARD

For ‘Wave with Pallet’ profile run only (see also ‘Wave’ profile run)

The logger has now been reset and is ready for you to start your profile run.

Disconnect the communications lead from the logger. The logger’s status LEDs briefly flash red and green alternately to confirm logger reset.
Plug the thermocouples into the logger s numbered sockets, and position the probes as follows:

Channel 4 on the logger must be connected to the right-hand thermocouple on the pallet (as viewed from above, with direction of travel pointing away from you), and channel 6 to the left-hand thermocouple.
Channel 5 must be connected to the pallet s rear thermocouple.
If required, channels 1 3 may be connected to a dummy PCB (if fitted) or a product.

If using a non-Datapaq pallet, you must specify in the wizard the distance by which probe 5 is behind probes 4 and 6.

After the thermocouples are attached, ensure the mating surfaces of the thermal barrier mounted securely on the pallet, if used are clean and undamaged. A good seal between the barrier and the thermocouple cables is essential if the logger is to be protected. Put the logger in place in the barrier, laying the thermocouple cables across the sealing material to exit the barrier at the cutout.
Press and hold the logger s start button for about 1 s until the green LED starts to flash. Insight automatically sets the sample interval at 0.1 s for all wave-solder profiles to ensure accurate line-speed and contact-time measurements.
Close the barrier lid firmly with a click, ensuring a good seal around the thermocouple cables.
Place the pallet/logger/barrier/PCB assembly (depending on configuration) on the oven s conveyor. With a pallet, ensure correct direction of travel, as marked on the pallet (the fixed thermocouples enter the oven first).

Click Next in this dialog when the profile run is complete and you are ready to download the data.

Logger Has Been Reset – – WAVE SOLDER WIZARD

For ‘Wave’ profile run only

The logger has now been reset and is ready for you to start your profile run.

Disconnect the communications lead from the logger, the logger’s status LEDs briefly flash red and green alternately to confirm logger reset.
Plug the thermocouples into the logger s numbered sockets, and attach probes to the product or test-piece as required. The thermocouples used to monitor the wave (whose data is to be used subsequently in the Wave Solder analysis) must be fixed in such a way that they contact the main wave, i.e. on the solder side of the PCB; these thermocouple numbers must have been specified earlier in the wizard. Other thermocouples can be connected to either side of the PCB as required.
After the thermocouples are attached, ensure the mating surfaces of the thermal barrier mounted securely on the pallet, if used are clean and undamaged. A good seal between the barrier and the thermocouple cables is essential if the logger is to be protected. Put the logger in place in the barrier, laying the thermocouple cables across the sealing material to exit the barrier at the cutout.
Press and hold the logger s start button for about 1 s until the green LED starts to flash. Insight automatically sets the sample interval at 0.1 s for all wave-solder profiles to ensure accurate line-speed and contact-time measurements.
Close the barrier lid firmly with a click, ensuring a good seal around the thermocouple cables.
Place the pallet/logger/barrier/PCB assembly (depending on configuration) on the oven s conveyor. With a pallet, ensure correct direction of travel, as marked on the pallet (the fixed thermocouples enter the oven first).

Click Next in this dialog when the profile run is complete and you are ready to download the data.

Select Process File – – WAVE SOLDER WIZARD

You may choose a process file to apply to the results. Click Use No Process File if you do not want to apply a process file.

The process files shown for selection are only those suitable for either ‘Wave’ or for ‘Wave with Pallet’ profiles, depending on which type of profile run you are performing (as selected earlier in the wizard). The list of files shown are those contained in the default process file directory, but you can also click Browse to locate files which you may have stored elsewhere.

If you do not wish to apply a process file at this point, you can still apply one subsequently.

When the wizard closes, the newly downloaded data appear on screen as a paqfile and can be displayed and analyzed as you wish.

To view and analyze the data at any time in the future, you will need to save the downloaded temperature profile data.

Wave Solder – – WAVE SOLDER WIZARD

The Wave Solder Wizard guides you through the process of producing a temperature profile (paqfile) using data from a wave solder oven. A profile produced in this way differs from other paqfiles in that the data can be subject to a Wave Solder analysis selected by clicking a tab which is then present in the Analysis Window.

The logger used with the Wave Solder Wizard must be a Datapaq 9000 or Q18.

You may choose either to:

Perform a complete temperature profile run using a wave solder oven (i.e. to reset the logger, perform the run through the oven and download the results), or
Download from the logger the data from a profile run that is already stored there.

The procedure is largely self-explanatory: enter information as prompted by the wizard, then click Next at the end of each stage.

What is a Process File?

A process file contains data on the product you are passing through the oven and the conditions to which it is subject while it is in there.

After a product has been through the oven and a temperature profile (paqfile) of the run has been obtained, much of the information contained in the process file can be displayed visually, in combination with the temperature profile, to assist in the profile’s interpretation and analysis.

All the information and options held in a process file can be applied individually to a paqfile, but especially if the run is to be repeated with the same product and the same conditions it is normally more convenient to hold all this information together, in a process file. It can then be applied to the paqfile in a single, simple step.

The data included in a process file are on:

The oven specification (i.e. its fixed features) length of oven, and number and lengths of oven zones.
This information can also be held separately in an oven file.
The recipe used (i.e. variable factors which are applied to the product during the process or are used to specify details of the analyses which will be performed on the resulting temperature profile) oven zone temperatures, oven line speed, convection level, line width, oven start definition, use of tolerance curve, and analysis options.
This information can also be held separately in a recipe file.
The product a picture, dimensions, probe positions, and the means to be used to compensate for these differing positions during the analysis.
This information can also be held separately in a product file.

The process file and oven, recipe and product files can also contain names and notes to help you identify and use them.

A process file can thus be created by combining separate oven, recipe and product files.
