Experts, Today I received PCB in a punctured vacuum seal bag. the Humidity indicator change the colour to pink at 60%RH mark. The brd finish is Entek. Earlier our intention to get the board vacuum seal is because we want to ensure that the is no fr

Reject the batch of boards. Take one board, dry it, then check for solderability. If its good, do the rest. If not.....? Contact the PWB vendor for reccomendations.

Dear all, We have a PCB design mistake that causes exposed copper layers on the edges of breakaway locations. Although we fixed the design, but we already made a lot of boards plus many made before we found the problem. I wonder if any one have some

We are trying to eliminate/minimize the baking process for high lead-count ICs. We would like to reseal packages containing these parts to minimize exposure to humidity. Anyone have or know of a way to reseal or vacuum pack parts? Any suggested eq

Dennis, I've seen this before, and in our case we didn't need to seal the edges because there was no concern of shorting or anything in the end product, this is a choice you will have to make, Does your end product have any protrusions or mounting h

Very simple, you just buy a commerical-grade vacuum sealer. It's not that expensive. A small tabletop unit cost $2000 - $4000. I don't have a number handy. E-mail me off-line if you require more info. Regards Matthew NII, Norsat Internationa

Has anyone experienced electrical shorting between adjacent leads of a ceramic hermatic sealed IC? If so, can you share root cause and corrective action? The shorting appears to be in the glass frit seal itself but the failure mechanism is unknown. A
