TechNetters,

Is there chemistry available to remove oxidation
from gold tips without compromising
solderability?

More specifically we have a costumer that has
sent back some boards that have been stored
for almost a year.  The gold tips are tarnished.
The customer has requested that we rework the
boards, without out buffing the gold out.  An
analysis of the thickness gives 40 microinches
of gold on 300 microinches of nickel.

Many thanks,

Chris Rucinski
Process Eng.
