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. WitrynaThe main consideration when using immersion silver, although being a great alternative to gold immersion, silver immersion introduces the possibility of oxidation. We do take steps here at Bittele to avoid this. Bare hand contact with the boards is eliminated by the use of gloves as this finish is very sensitive to tarnishing.
