Immersion silver finish
WitrynaImmersion Silver is also called immersion Ag. It is the standard finish at Pandawill Circuits and is RoHS compliant. It is an improvement on HASL being exceptionally flat, and can replace Immersion Gold over … WitrynaImmersion Silver. Immersion Silver (IAg) is applied directly to the base metal of a PCB via chemical displacement. It’s a more affordable option than ENIG, and it is also RoHS-compliant. A typical thickness for Immersion Silver is 4-12u”. Due to the way copper and silver interact, they eventually diffuse into one another.
