For years our various PCB suppliers have tried to convince me that all
the problems with ENIG have been overcome. About the time I begin to
consider possibly moving to it, someone on this forum, usually a PCB
supplier, will post that there's no reason to avoid ENIG and there are a
dozen or more responses disputing it with personal experiences. Those
exchanges continue to reinforce that the decision I made years ago to
use Immersion silver on our products was, and still is, a sound one.
I just wanted to say "Thanks" to everyone who contributes to this forum
for helping all of us in making good decisions for our respective
businesses.

I installed the first immersion silver line in North America in 95. We
built millions of boards with this finish and the only issue brought to
my attention was exposure to a sulfur environment. Multiple reflows did
not present an issue and we stored the boards at customer sites for over
a year without a problem. Our customers did not find it necessary to use
gloves in the assembly operation.
Best regards

Subject: [TN] Immersion Silver
Good Afternoon,
Any concerns about using immersion silver as a finish. PWB has to take
two
reflow cycles, 1 re-work cycle and one hand solder after the two
reflows.
Parts have to be transported from one part of the country to another
after
the two reflows. Thanks. Steve Kelly
