Nickel plated copper foil: an important material in modern electronics industry

Nickel plated copper foilIt is a high-end electronic material with excellent conductivity and corrosion resistance. It is made by sequentially depositing nickel and copper layers on the surface of the substrate. Nickel plated copper foil can be widely used in semiconductors LED、 Photovoltaic, display and other fields are indispensable and important materials in the modern electronics industry.

The preparation process of nickel plated copper foil usually consists of three steps: preparing the substrate, nickel plating layer, and copper plating layer. Firstly, choose a suitable substrate, usually polyimide film or polyimide composite material; Next, a layer of nickel and a layer of copper are sequentially deposited on the surface of the substrate, which can be achieved through methods such as electrochemical plating or physical vapor deposition.

Nickel plated copper foil has the following advantages:
1. Good conductivity: Copper plating can improve the conductivity of the substrate, and the adhesion between the copper plating layer and the substrate is strong, making it difficult to peel off, thus ensuring high-quality conductivity.

2. Good corrosion resistance: The nickel plating layer can effectively prevent oxidation and corrosion, maintain the stability of the substrate surface, and extend its service life.

3. High temperature non deformation: Copper plating can improve the strength and stiffness of the substrate, so that it will not deform or lose its original properties even in high temperature environments.

4. Good processability: Due to its excellent flexibility and processability, nickel plated copper foil can be easily processed in various ways, such as cutting, bending, stamping, etc.

5. Environmental Protection: Compared with other electroplating processes,Nickel plated copper foilThe preparation process is more environmentally friendly, reducing the discharge of wastewater and exhaust gas, and meeting the requirements of modern green environmental protection.

Due to its many advantages, nickel plated copper foil is commonly used in the following industries:
