Hello All, We are looking at a surface presure contact application between an EMI/RFI braid against an immersion silver surface finish that has undergone 2 SMT and 1 wave process. I know the immersion silver oxidizes (tarnishes) but everything I read indicates that the oxide is also highly conductive. Still, I was wondering if the long time users of immersion silver have come across LLCR data for immersion silver as well as LLCR of the oxide.
