Dave,
        We use a system from Derby Associates (http://www.derby.com). Derby
is a spin-off from HP (now Agilent) so the system integrates nicely with
Agilent testers, but it will work with any vendors test equipment. The nice
feature of this system is that you import your CAD files and when there is a
failure at test the repair operator sees a picture of the board on their
computer screen with the failure highlighted in Red. They touch the
component (if you are using a touch screen) and then can highlight the
repair code. This system works nicely because not all boards have reference
designators in the silk screen. Touch-up operators also use the system, in
this case they act like testers (highlight bad joint) and a repair operator.
The system keeps track of the test data, repair data and makes sure if the
board has been repaired that it actually passes test after being repaired
before going onto the next process step.
        We have written our own manual data collection application, using
touch screens, that pushes data in the same data collection format and we
have our functional testers, (even acoustic testers) pushing data in the
same format.
        The system runs on Unix boxes in our facility but they do have some
customers using NT. If you need any more information, you can contact me
off-line.

Regards,
Chris

Subject: [TN] Defect data tracking software


I'm looking for recommendations for an off the shelf defect data tracking
software package for tracking SMT defects by reference locator and defect
type for a high mix/low volume contract manufacturer. At this time, I'm not
interested in SPC data as much as getting simple pareto charts showing some
trending over many individual work orders. It would be nice to be able to
use the same software to track yield data from the test technicians also.

I should explain that we have an Access database a summer intern wrote for
us that collects the data but can't trend it for us. It is written in fairly
complex code that is difficult to modify without spending lots of time
working at it. We're thinking we'd be better off to stick with a canned
program that we can customize to out needs.
