OK... but what's the recommended chemistry (or what choices are there) and
what's the recommended thickness?

Hi Jim! The 4-14 Plating Processes subcommittee is currently working
on
specifications for immersion silver and immersion tin. ENIG was
covered
with the publication of the IPC-4552 specification. I would
recommend you
call out the specific immersion silver chemistry, a thickness range
and a
solderability requirement on your drawing note(s) until the 4-14
committee
can complete their work. Good Luck.

Hello Technet:
What's the best way to specify immersion silver finish on a PWB? In
accordance with what? Thickness? Anything else?
