ENIG boards have low shelf life as oxidation starts showing up quickly on the solderable areas. We usually keep them vacuum packed till they are ready to be assembled. Most PCB manufacturers will send them vacuum packed.

Greetings, We are discussing what should and what should not be baked and vacuum packed. Should we just concentrate on the fine pitch packages and the bga's? What about those components which come on blister tape, should they get baked and re-packed

"Usually people use the vacuum to remove air and then replace with nitrogen to eliminate oxidation and a medium for bacterial growth. Why anyone would need to vacuum pack a pcb is beyond me, though. " We might get a batch of 400 pcbs in but the kit

Some things you have to be sure of... Can you guarantee the LEDS are DRY when you receive them ? They may be packed in dry bags but when was this done and has the LED distributor had them open at his site ? Using vacuum sealed dry packs is a good way
