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.

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.

PCB Finishes: Immersion Silver - Nova

WitrynaImmersion silver is a type of surface finish used on PCB surfaces. PCB manufacturers protect the exposed copper pads with immersion silver. This material, immersion silver, is commonly used for EMI shielding and aluminum sir bonding. Also, immersion silver finish’s thickness ranges from 5 to 17 micro inches. WitrynaThe current, common finishes like Electroless Nickel Immersion Gold (ENIG), Immersion Silver and organics like Organic Solderability Preservative (OSP) provide much better planarity and smoothness for finer pitch devices. An example of such devices would be a Ball Grid Array (BGA), a Quad-Flat No-Leads package (QFN) or a … WitrynaHere are attributes of ImAg surface finish: 1). Excellent solderability, relatively high wetting ability and capable of meeting requirement of multiple reflow ; 2). Suitable for wiring bonding and pressure contact … cryptocurrency theft attacks
