Immersion Tin Pcb - China

The Immersion Tin surface finish describes a very thin layer of tin, applied over the copper layer of a PCB.

This method is a Lead-Free PCB alternative that produces a consistently flat surface, which solders well and is cost-efficient.

The tin layer’s appearance is usually mostly white, so the finish is sometimes referred to as White Tin, and is applied to the copper using an electroless chemical bath.

This tin surface finish can protect the copper beneath from oxidation throughout the PCB’s intended shelf life.
