Surface Finish：Immersion Gold

Immersion gold is a process that applies a very thin layer of gold with displacement of the surface atoms. It means the coating of immersion gold PCB is not very thick, and it can be used for extending the shelf life of parts waiting for soldering operations because of corrosion resistance. Immersion gold has been applied in aluminum and gold wire bonding and PCB fabrication. But it can’t be used to take place electrolytic gold plating because its thickness and adhesion are limited compared to a standard electroplated gold.
