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.

In accordance with what? Thickness? Anything else?
