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.

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

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

Hi, are there any component types that are not suitable for vacuum reflow ? I've had one customer use his vacuum vapour phase reflow system on a pcb, and on 10% of the hermetically sealed accelerometers devices. the lids have popped off... Thanks Gra

I've only used vacuum reflow on LED boards but I have heard that Vacuum may need to be reduced depending on components. I can't find the source at the moment but it was a study done by Heller I believe. I would experiment with different levels of v

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
