are huge and the space between them fits all sorts of things,
such as etchant, oxygen, mercury, uranium hexafloride, and
other fun stuff. The gold, if plated too quickly, gets a
little mossy, which is why it appears matte finish rather
than shiny, and makes it even more susceptible to infiltration of
undesirable things. For instance, the electrolyte in batteries
like alkalines and nicads goes right through gold plating...
As a result, the mil specifications for gold plated fingers
requires a thin layer of nickel plating between the copper and
I worked at one company, Defense Electronics, Inc (DEI) as a
metal plater, and they routinely flouted the rules on gold
plating. It wasn't so much that they didn't want to follow
the rules, but rather, that they couldn't afford my time, and
their money, to repair/replace their nickel plating tank. So,
they doubled up on the gold plating... at $32/oz, why not?
I later went on to a company called Electro Products, Inc, which
made circuit boards, and they too cheated on the gold plating,
no nickel inter layer.
To be fair, there was a lot of inbreeding amongst the defense
related electronics companies back then...
