One of our aerospace customers "suggested" we vacuum seal MSD components. We bought a vacuum sealer and we are deciding whether or not to vacuum seal ALL MSD parts or just aerospace. Our current method consist of desiccant, a humidity card and a bag

In previous lives we vacuum sealed all MSD devices. Also a nitrogen chamber can be used for unsealed bags. You can check the J-STD-033 and J-STD-020A for handling of the different levels, bake times etc. Good Luck!

We manufacture according to military Class 3 standards and we do not vacuum seal any MSD devices. Your current method of dry packing is sufficient as well as dry cabinet or nitrogen storage. A light evacuation of air during the dry packing process

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

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
