Does anyone know of a test method to measure the resistivity of gold
plating?  We have a product that has a spec on the plating material and
refers to IPC-TM-650 method 2.5.14, however this method is for copper foil,
not plating.  Is there a reason our customer might want a resistivity spec
on just the plating?  Doesn't it make more sense to spec the final material
(copper foil plus plating), in which case, method 2.5.14 would work?

Prior to plating, the gold is in solution.  Is there a resistivity test
method for solution form?

Any help on this is greatly appreciated.
