Immersion silver finish
WitrynaImmersion Silver Surface Finish. Immersion Silver (also called immersion Ag) is a RoHS compliant (lead-free) surface finish that is an ideal choice for flat surface requirements and fine pitch components with reasonable costs. This surface finish can also replace Immersion Gold over Electroless Nickel (Au/Ni) for most applications. WitrynaImmersion silver or ENIG. I've been designing circuit boards professionally now for just over 3 years. The field is defense. For reasons that have been been quite made clear to me all the boards I've worked on have been immersion silver finished. This send to have favorable properties for high RF and does a decent job maintaining solder ability.

Immersion silver plating (or IAg plating) is a surface plating process that creates a thin layer of silver over copper objects. It consists in dipping the object briefly into a solution containing silver ions. Immersion silver plating is used by the electronics industry in manufacture of printed circuit boards (PCBs), to protect copper conductors from oxidation and improve solderability.
