In a former position we set up a sequence of three stamps, and maintained a
log book on the shop floor by serial number. Boards were stamped, post
solder inspection, test, and final. We had a system that relied on 100%
inspection.
In a system of lot samples. I think I would continue the practice of
stamping those members of lot that were choosen for inspection. and maintain
the log by lot/serial.

I am sure that a good system could be developed using bar-codes and
scanners. In an envirionment with MRPII or an ERP system this would make
more sense.

Hello All,
Is it common practice to QC and Date stamp a PWA after final inspection?
What are you folks out there doing for traceability in the CEM world?
