Double gloss nickel plated gold plated copper foil

Double gloss nickel plated gold plated copper foil is a high-performance composite material, which is coated with a layer of nickel (Ni) and a layer of gold (Au) on both sides of high-purity copper foil. This composite material combines the good conductivity of copper foil, the wear resistance and corrosion resistance of nickel layer, as well as the low contact resistance and excellent welding performance of gold layer. This product is widely used in the electronic manufacturing industry, such as PCB (Printed Circuit Board) manufacturing, connector manufacturing, semiconductor packaging, and other fields.

Product characteristics

1. Excellent conductivity:
   • Copper foil has excellent conductivity and is suitable for applications that require high conductivity.
   • Suitable for producing high-performance electronic devices and circuit boards.
2. Protective performance of nickel plating layer:
   • The nickel layer has good wear resistance and corrosion resistance, which can effectively prevent copper foil oxidation and corrosion.
   • Extend the service life and reliability of the product.
3. Low contact resistance of gold plating layer:
   • The gold layer has extremely low contact resistance and is suitable for connectors and contacts that require low contact resistance.
