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.

Mit freundlichem Gruß
Kind 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?
