Immersion Tin PCB

Immersion Tin is the lead-free alternative to the Hot Air Leveling(Hasl) process on pcbs. On printed circuit board surface and the
bore holes,the thickness of Tin is between 0.7 μm and 1um.

The tin layer protects untreated copper from oxidation; it is a perfect foundation for soldering applications, as well as for plug
contacts during the production of Printed circuit Board.

Within the electronics industry,immersion tin is recognized as a reliable surface finish for both PCBs and IC substrate applications.
It is used in many market segments, such as automotive, communications, consumers and industrial electronics.
