Surface treatment

Electroless Gold Nickel (ENIG)

The finish is composed of two layers placed through a chemical process: a nickel layer and a gold layer.

Gold gives the final coating and nickel is used to prevent gold from migrating to copper.

This finish withstands several soldering cycles and long periods of storage.

  • Automatic or manual vertical lines
  • Electrolytic process or non-electrolytic process (ENIG).
