We have been using ENIG now for about three years and have had no bad

Hi Steve,
I do not know about "bad-mouth ENIG"--I am a reliability consultant, and
have
had plenty of calls because of ENIG related failures, but not a one about
iAg. On the other hand, I do not know about their respective environmental
implications.

Regards,
Werner Engelmaier
