Subject: [TN] ENIG Thickness Standard?


> Is there a standard for the plating thickness of the ENIG surface

> nickel to 200u inches. A couple of our board vendors are telling me that
> that is excessive and that anything over 100u inches is overkill. I've

> inches.  What (if anything) is considered standard for this finish?
