if the hardness of your gold contact not match with slot, and/or the
gold quality inferior compare to the slot, you are asking for
trouble. (especially, for low voltage contact). my 2 cents. there
are many guideline for zif insertion contact... do a google search
will do you a lot of good. good luck.
