Gregg,

As a general rule...NO, you do not have to worry about gold
embrittlement when using gold plated boards.  

99.9999% of gold boards are ENIG which has negligible amounts of gold.
As others have already mentioned, electroplated gold is a different
story and one does need to be careful.  However, electroplating does not
happen by accident.  You have to go to the extra trouble and
specifically design for and request the thicker gold.  Then the board
shop will likely try to talk you out of it unless you insist.

Dear TechNetters,

One of my students has a good question, I can't answer. J-STD-001
requires gold removal of various gold plated components/terminals. What
if you are using a gold plated board plating. Is there generally any
problems with gold embrittlement with this type of board plating with
non-gold plated leads for through-hole or SMT components?

Your thoughts would be most appreciated.
