Immersion Tin (ImSn) is a metallic coating of ?Tin?, which is deposited directly over the top copper layer of a PCB using an electroless chemical bath process. PCB finishes are used to protect the copper tracks and pads on printed circuit boards while in storage. Immersion Tin forms a dense uniform coating (0.8 to 1.2 micrometers) with good hole wall lubricity. Its appearance is usually White, so it is also called ?White Tin?.
