The manufacturing process and performance characteristics of the copper foil product will be analyzed in detail below.

1、 Manufacturing process

1. Copper foil production: Firstly, copper foil production needs to be carried out, including the selection, heating, and rolling of copper billet materials, in order to obtain copper foil substrates that meet the requirements.
2. Surface treatment: After the production of copper foil substrate is completed, its surface needs to be treated to increase its surface energy and adhesion. The commonly used surface treatment methods include cleaning, activation, acid washing, oxidation, and chemical tin plating.
3. Coating antioxidant: After surface treatment, it is necessary to coat the copper foil surface with antioxidant to increase its antioxidant performance. Antioxidants can be used as red phosphates, nitrates, sulfates, chromates, and tin oxides, and their coating methods can include spraying, rolling, and brushing.
4. Tin coating: After the antioxidant coating is completed, the copper foil surface needs to be tinned to increase its conductivity and corrosion resistance. Tin plating can be achieved through methods such as chemical tin plating or electrolytic tin plating, and its thickness is generally 1-5 microns.
5. Coating shielding layer: After the tin plating layer is formed, it needs to be coated with a shielding layer to increase its shielding and protective properties. The shielding layer can be made of metals such as silver, copper, nickel, or carbon fiberconducting materialThe coating method can be spray coating, roller coating, brush coating, etc.

6. Testing and packaging: After coating is completed, copper foil products need to be tested and packaged to ensure their quality and stability. Common testing methods include visual inspection, thickness measurement, conductivity testing, and shielding performance testing.
