Immersion Tin PCBs

Immersion Tin PCBs

Our company has involved in PCB manufacturing for more than 10 years, with advantage in quick-turn sampling and batch volume from 2-16 layers PCB with Immersion Tin Surface Finish. Immersion Tin (ISn) is a metallic finish deposited by a chemical displacement reaction that is applied directly over the basis metal of the circuit board, that is, copper. The ISn protects the underlying copper from oxidation over its intended shelf life.
