Structure and characteristics of PI nickel and copper plated film

PI nickel copper plating film is a composite material formed by sequentially plating nickel and copper on the surface of polyimide film. Polyimide is a high-performance polymer material known for its excellent heat resistance, corrosion resistance, good mechanical strength, and electrical insulation properties. The addition of nickel and copper layers not only inherits the above advantages of polyimide, but also endows the material with high conductivity, making it an ideal choice for high-performance electronic components.

1. Heat resistance: Polyimide is one of the most thermally stable polymers to date, allowing PI nickel and copper plated films to maintain stable performance even in high temperature environments.
2. Conductivity: Both the nickel layer and the copper layer have good conductivity, with copper having particularly outstanding conductivity, ensuring the electronic components' demand for current transmission.
3. Mechanical strength: Polyimide film itself has high strength and toughness, making PI nickel plated copper plated film less prone to damage when subjected to external forces.
4. Electrical insulation:PI nickel plated copper plated filmInheriting the electrical insulation properties of polyimide, it ensures the stable operation of electronic components in complex electromagnetic environments.

The Influence of Nickel and Copper Layers on Conductivity

The nickel layer and copper layer play a crucial role in PI nickel plated copper film, as they not only determine the conductivity of the material, but also affect other physical and chemical properties of the material.

1. The function of nickel layer:
   • Improve corrosion resistance: The nickel layer has good corrosion resistance and can protect the substrate from chemical corrosion, thereby improvingPI nickel plated copper plated filmThe service life.
   • Enhanced adhesion: The nickel layer, as an intermediate layer, can enhance the adhesion between the copper layer and the polyimide film, improving the stability and reliability of the coating.
   • Adjusting conductivity: Although nickel layer has lower conductivity than copper, its presence can optimize the conductivity of the coating, making it more uniform and stable.
2. The function of copper layer:
   • High conductivity: Copper is an excellent conductor with extremely high conductivity, which can meet the high requirements of electronic components for current transmission.
   • Cost reduction: Compared to other precious metals, copper is more affordable, and the use of copper layers can effectively reduce the production cost of PI nickel plated copper plated films.
