hi,

sorry i can't answer your question, but i do have a comment.  do you think
that this thickness (thinness) of gold will provide the protection you are
looking for?

Subject: [TN] Gold plating specifications


Good day all,

I am going to specify gold plating on a PCB and am curious as to how the
rest of the world specifies such things.

The board is FR-4, double sided with 2 oz copper.  The quote I currently
have  is for electrolytic plating 0.05~0.20um thick.  The board is
populated with both through hole and SMT components.

The purpose of going with the gold plating is to keep the pads under an
elastomeric connector from oxidizing.  Oxidation on these pads has caused
problems with segments of an LCD becoming dim or blank.

Thanks in advance for the assistance.  With the exception of a few flaming
jerks, this is a great board.

Scott
