12.3 Auto Defect Correction (ADC)
This tool has 2 mains goals:
It gives you a precise status of the customer library:
• Links which are never used.
• The best links arrangement to reduce the cycle time and to increase the accuracy.
It allows you to improve the customer library by downloading models from the standard library.
12.3.1 Principle
Running boards from the production line with the customer and/or the standard library.
The ADC mode gives you a verdict about the best models to use from the customer or from
the standard library.
After testing several panels, it informs you about customer models which are never used and
about standard models we can use.
Then, you have the possibility to:
Remove unused customer models from the customer library.
Add standard models to the customer library.
12.3.2 Algorithm
Possibility to run empty boards with customer and standard libraries to detect models which
give false acceptance.
Test full panels with the customer library. If a Ref. Designator fails we try with the standard
model in the standard library.

12.3.3 Limit
The standard name of the customer model must exist in the standard library.
This field is editable by double clicking on the string
Model name from the model description window of
the library.
In the customer library, you can not have duplicate
standard names. The software rename them auto-
matically.
Research for the corresponding standard name:
To run ADC, the software analyses if the standard name of the customer model exists in the
standard library. Then it looks for the head link and executes all the links from the model family.

12.3.4 Configuration
To access the ADC parameters window, go to the production screen and click Ctrl+Shift+A.
You can display this window at any time during production.
In
Standard library (A), select the standard library to use.
The
Customer library (B) comes automatically from the .tst file.
In
Number of full panel (C), enter the total number of full panels to use for ADC calculation.
In
Sampling on full panel (D), enter the sampling on production boards for full panels.
Ex: 1 board on 10 will be used for ADC data collection.
In
Number of empty panel (E), enter the total number of empty panels needed to run ADC
(to check false acceptances).
In
Picture of component validate by a standard model (F) section tick Save image if a
model from the standard library validates a component, to check if it is a good acceptance or
not. Same for empty boards to check false acceptance. In
Saving folder, select the folder
to save images.
In
ADC file (G), load an existing ADC file and complete it with new data. You can save the
ADC file with a new name.
After setting all the needed information, press
Start (H) button to launch the ADC mode.
If you select
Exit ( I ), you will discard the changes.
