Immersion silvers are self-limiting, and always much thinner than ED.
They vary from 5-10 millions of an inch.

Good morning TechNet,
One of our drawings for an RF PCB calls out "Silver Plate per QQ-S-365,
electrodeposited, Type I, 0.0003" thk." The supplier that we are
getting quotes from says he can't do electrodeposit and wants to supply
immersion silver boards.
Are these two processes equivalent? I searched the archives and cannot
find any references to ED silver. Has immersion replaced this process?
(Our drawing is pretty old.)
The board material is Duroid 5880. would this make a difference?
Thanks for your help!
