It seems to me that I have heard people say you can attempt to
rework/reclaim OSP finish boards that may have degraded? Strip the
coating and the copper oxidation, and re-apply OSP?
We have a large stock of a PCBs with OSP finish that we were left with
when an OEM contract got severely reduced. We have been whittling away
at the stock for the reduced orders, but now it is over 2 years old, and
we are starting to see problems with solderability.
Would you go back to the original manufacturer for the rework process,
or would you go to some specialty house for this?
A wrinkle, possibly is that there are areas of selective gold plating as
well on the board.
