Copper foil gold plating

Copper foil with gold plating, also known as gold-plated copper foil, is a thin metal foil with a metal coating on the surface of the copper foil substrate. The coating material is usually metal such as gold, silver, nickel, or advanced materials such as graphene. Copper foil gold-plated products play an important role in modern industry due to their unique properties and wide range of applications.

Product characteristics

1. Thin: The thickness of gold-plated copper foil is very thin, such as the common 0.018mm thickness, making it significantly advantageous in situations that require high precision and lightweight.

2. Corrosion resistance: The dual protective layer of copper foil substrate and metal coating can effectively resist chemical reactions such as oxidation and corrosion, extending the service life of the product.

3. Plasticity: Gold plated copper foil has good plasticity and can be bent, cut, and processed according to needs, making it convenient for use in products of various shapes.

4. Conductivity: Copper foil itself has good conductivity, and metal coating can further improve its conductivity, making it suitable for the manufacturing of electronic components and other fields.

5. Aesthetics: The metal coating endows the gold-plated copper foil with a good appearance texture, making it not only functional but also decorative.

Production process

1. Cleaning substrate: The copper foil substrate is cleaned by mechanical or chemical methods to remove impurities and oxides on the surface, ensuring the adhesion of the metal coating.

2. Gold plating treatment: Place the cleaned copper foil substrate in an electroplating bath and evenly cover the metal coating on the substrate through electrolysis. The selection of metal coating can be based on specific needs, such as gold, silver, nickel, etc.

3. Surface treatment: Polish and polish the gold-plated copper foil to improve its surface smoothness and aesthetics.

4. Testing and packaging: Conduct quality testing on gold-plated copper foil, such as thickness, conductivity, and other indicators. After passing the inspection, package it for transportation and use.
