Does anybody know of a specification requirement for the roughness of gold
as plated on top of a copper feature on a printed circuit board.  If so
please let me know what spec it is in and what the criteria is.  I seem to
remember it being in the IPC but I can not find it.

My apologizes if this same question has gotten to the forum twice.  My
first note seemed to have been bounced back.
