5. Adjusting Threshold Settings for details on this topic. Track Score can be useful for trend analysis to

quantify pass/fail scoring deviations.

6. If the Track Shape Score Check Box is checked, the system will send shape score to the selected

Data Destination SPC data file. Shape score relates to the shape of solder elements (This requires

Solder Inspection to be enabled in the Function / Options Dialog Menu).

7. The Track Device Position Offset check box enables/disables position offset tracking for devices.

Since each board could have thousands of devices, it is time and memory consuming to track all the

data for all the devices and is therefore NOT recommended.

8. The Total # of Board Data to Track numerical entry field sets the maximum number of boards to track

before data logging automatically stops. The default setting is 10,000 for a Data Destination to Excel™.

NOTE: Data logging to an ASCII text file is unlimited.

9. Data Save Frequency specifies how often data should be saved to disk. A value of [1] will log data for

every PCB; whereas a value of [10] will log every 10th board.

10. The Always Append option is used to continually add data to a single file in lieu of saving separate

files for each board tested. If the SPC Logger is enabled, when a board setup is loaded the AOI Mode

software will prompt the user with a SPC Logger Append Dialog Box containing three options:

a. Append

b. Start New Log

c. End Data Log

The <Always Append> Check Box in the SPC Log Setup Dialog overrides the Append popup during

inspections and once enabled this popup will no longer be displayed. Therefore, the only way to

uncheck Always Append is from the SPC Data Logger Setup Dialog.

11. The Data Destination option has a file path entry field and three file type options:

a. Excel

b. Text File (ASCII)

c. ODBC

1. If Excel™ Data Destination is selected. The software will send data to an Excel™ file using the same

name as the BSU. For example, “MyBoard.BSU” will result in a “MyBoard.XLS” workbook SPC data file.

If multiple board setups are loaded and boards are inspected; then multiple workbooks will be created

in Excel™ to store their data.

CAUTION: Excel™ opens in the background during data logging. DO NOT close Excel™ as doing

so may cause the software to crash when it attempts to communicate with Excel™.

2. At the end of an inspection session (when the Cancel Inspection Button is pressed) data is saved to

disk using the same name as the BSU file. By default, the data directory is C:\Data\. Operators can use

the Excel™ File / Save As function to store data to a different location. I.e., a network drive, thumb

drive, etc.

3. VB Macros. It is possible to create an Excel™ workbook for a particular board setup and have the AOI

software use it as a template workbook when creating new workbooks. This will allow the user to
