Dave,
You are right about stacking and shelf life. In this area ENIG is
unsurpassed.
Other benefits include rivetiing the thru hole with Ni, ENIG boards give the
highest value for IST testing.
ENIG does not tarnish over time, it does not form micro- voids and more
important it does not corrode in "S" rich environments.
The Ni also protects the underlying copper from dissolution at assembly.
Shops that practice process control should have no problems making ENIG
boards that do not exhibit any Ni corrosion.
Best of luck in your decision.
Regards
