Hello all, Can anyone advise if any standard covers ENIG plated boards shelf life? Or share what you do for bare boards storage and expiration criteria?

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.

If they are vacuumed and they approach 6months or 1 year mark, what would you do?

Probably preform some sort of solderability evaluation on the PCBs.

Thank you Stephen... I also mistaken it with Immersion Silver.

kumarb would you just check PCBs for solderability or would you do something in addition?

The G in ENIG is gold. It does not oxidise. Either you are thinking of OSP or your board shop is providing defective boards if your boards show oxidation. It would be the nickel that is oxidising but should be totally covered by the gold. Is there

The solderability shelf life of ENIG is related almost entirely to diffusion of O2 through the gold plating. When O2 diffuses through the gold, the underlying nickel is oxidized rendering it unsolderable (with ENIG - you solder to Ni, the gold dissol

Hi guys, I will be building a wireless minicam setup and would like some advice. All the parts I want to use should be off the shelf since I really don't have the knowledge to build these parts. Requirements: color video, small, easy to hide minic
