Q1:Immersion Silver (ImAg) PCB Surface Finish
A1:Immersion silver (ImAg) is a metallic coating of pure silver (0.1 to 0.4 μm), which acts as a preservative for the copper traces on a printed circuit board. It is a combination of 99% Ag metal with traces of organic material. With time, ImAg forms Sulfide Dendrites that cause a shorting problem. This problem can be avoided by applying a thin organic coat, which acts as a barrier.
An Immersion silver (ImAg) finish on a PCB is suitable for the applications that include flat surfaces like membrane switches, EMI shielding, aluminum wire bonding, and very fine traces.
