Plastic composite copper foil has excellent thermal stability and can effectively resist the effects of high and low temperatures

Plastic composite copper foilIt is a new type of high-performance composite material composed of various plastics and copper foils, which has excellent electrical insulation, heat resistance, corrosion resistance, and arc resistance. Therefore, it is widely used in the packaging of electronic devices, chip packaging, and sensor manufacturing. The production process of plastic composite copper foil is to first treat the surface of the plastic, then composite it together and cover it with a layer of copper film, and finally perform heat treatment to form the final plastic composite copper foil. Plastic composite copper foil has excellent thermal stability, which can effectively resist the effects of high and low temperatures, suppress the deformation and damage of electronic components, and thus improve the reliability of electronic components.

In addition, Plastic composite copper foilIt also has good conductivity, which can effectively reduce the resistance of electronic components, improve the working efficiency of electronic components, and thus enhance the efficiency of electronic components. In addition, plastic composite copper foil also has good moisture resistance, which can effectively resist the erosion of humid environments, thereby improving the service life of electronic components.

Composite copper foil is a new type of current collector material for power batteries, mainly composed of three parts. The middle layer is a base film made of PET, PP, PI and other materials, and the two sides of the film are copper with a thickness of about 1 μ m. It is mainly a sandwich structure.

Different from the manufacturing process of traditional foil materials. Traditional copper foil is mainly produced by rolling or electrolytic processes; Composite copper foil is made by magnetron sputtering or vacuum evaporation on the surface of a plastic film with a thickness of 3.5-6 μ m, to produce a layer of copper metal layer with a thickness of 20-80nm. Then, the metal layer is thickened to 1 μ m by water electroplating to produce a composite metal foil with a total thickness between 5.5-8 μ m, which is used to replace 6-9 μ m electrolytic metal foil.

In short, Plastic composite copper foilIt is a very practical technology that can effectively block external electromagnetic waves and resist interference, thereby protecting internal electronic components from external interference. It can also improve the conductivity and moisture resistance of electronic components. Therefore, its application can significantly improve the reliability and stability of electronic components, making it a very practical technology. Therefore, plastic composite copper foil technology is expected to have greater development and application in the future.
