In my past life, we used selectively plated gold with Entek CU106-A successfully
for pressure contacts and switch contacts (to carbon ink actuators) without
issue. The gold was bussed in prior to the OSP application.
Some assembly houses are concerened regaring reflowing on immersion gold, as on
occasion, the solderability is not acceptable. N2 helps somewhat. The process
controls are vendor dependant.

Does anyone know if you can selectively plate with OSPs and Immersion
gold on the same PCB? I would like to do immersion gold on my keypad
contacts but use something Like Entek on the rest of the PCB. Is this
possible?
My PCB assembly vendor doesn't like reflowing immersion gold PCBs. He
claims the solder doesn't flow very well. Is it just him or the rest of
the industry?
