My experience was that we used silver for one of our products for the
last batch (on the advice of our assembly house) and the results were at
least as good as gold (price was the same, solderability was no problem)
but this is the first time we have used it. with thinking about lead
free I am fairly certain that silver should prove a better finish as it
doesn't add an extra intermetalic

Good to know, except, I need results based on a much larger sample &
technical comparison info. Since I have used gold successfully in the past,
I can't risk a test run silver based on 1 companies results.
Is there some sort of general PCB domain comparison between gold & silver?

Brian,
we went completely away from gold, nothing but problems in the soldering
process. Silver showed much better results for us. The price is about the
same. Maybe it depends on the assembly house and the processes they are
using.

I have just attended a meeting of the IPC Designers Council where the
subject of finishes for PCB's came up and it was revealed that Silver
Immersion seems to have great benefits for assembly, shelf life,
solderability, rework, etc...
Can anyone give me their experiences with the process and its benefits
and
down sides? Have you personally used it, how long, what sort of problems
have you seen, what are the cost issues?
Best Regards,

Good question. I would also like to know how it compares to Gold
Immersion.
I've gone all gold on all of my current PCBs as a means to improve overall
general quality.
(eg: http://pages.infinit.net/helloftp/bd2.jpg
A-LA-CARTE AV headend scalar & switcher PCBs.)
Is silver any better, or cheaper?
