Hi Sachin, thanks for your feedback. According to our supplier, surface plating is electrolytic gold over Nickel(not ENIG), but I think that is a still improper thickness for Au. (according to 3rd Working Draft from September 2008 of IPC 2221B "0.4

Hi, Does anybody know what is the minimum gold plating thickness on the PCB goldfinger required by the industrial specifications - IPC, Bellcore, etc. Where can I find the information? Appreciate for the help! Thanks, Tony

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?

I am designing an SMT pad for a ss metal switch. Finished copper thickness is .0014 and nickle-plating originally is 150 millionths. Initial testing yields 100,000 to 150,000 switches before intermitent failures (copper is reached.) I want 500,000

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?

Hi, No Major issue using lead-free plated components in tin-lead as long as Sn/Bi is not the finish. I think some customer might be worried about low melting phase. More voiding may be seen in case of ceramic capacitors used with tin-lead. It is
