Cecil, the board is a component.

Just askin but why would someone even want to subject an assembly to even 6 reflow cycles? As far as how many cycles that an assembly can be subjected to, wouldn't that be determined my your components?

Chances are this is not a component failure. First, these are passive components with passive testing on the ICT. He may have guarding issues, but more information is required as has been stated. Are all capacitors with the same P/N failing in dif

hi, lately I have problem with smd leds.After reflow 2-4% of leds are broken.I think , that reason is bad storage of components, because in our stock the tape with leds have not Moisture Barrier Bags.My question is ,how you storage components, which

Is this a new assembly/new test fixture/program? Or is this an existing assembly that is suddenly exhibiting this failure? Capacitors measured in circuit will not necessarily measure their correct values. Active components in circuit will be affec

I am wondering what skills operators need to run an smd line itself. At our company they know how the pick&place machine works (refill/ changover), but if there is a problem with wrong placed components they don't known what to do. Our managmenttea

The standard J-STD-033B.1 addresses how to store moisture sensitive components. A dry box is a good, convenient way to store MSDs, but there are other methods to consider which are outlined in the standard. Are you sure that the problems are caused
