Dear Technos,

 

What would be a reasonable false calls level? We are running a Mirtec table top and the latest report I've run shows a 50% ratio between the false calls count and the inspected PCBs count. I believe you've guessed, everything started when we've found missing components in test on boards that passed AOI and we tend to blame too many false calls levels, so that the operator has to click OK so many times, that he's missing some real defects.

 

And a question that begs for offline answers, what AOI machines have you tested lately and what your winners are? Are they able to reliably inspect solder joints? What the false calls levels are? Have you had the occasion to test them in a high mix low volume environment?

 

Thank you,
