PI copper plated filmIt is a thin film material with high strength, high heat resistance, and high conductivity. It is a composite film composed of polyimide film (PI) and copper film, commonly used in the production of electronic products such as flexible circuit boards, LED light strips, and high-speed transmission cables. This article will introduce the preparation method, characteristics, and application fields of PI copper plating film.
PI film preparation: PI film can be prepared using methods such as solution method, hot pressing method, and stretching method.
Among them, the solution method is the most commonly used method. Coat the PI solution on the substrate and form a PI film by drying and curing. PI film has high strength, high heat resistance, and high chemical stability, making it suitable for preparing PI copper plated films.
Copper coating: Coating a layer of copper film on the surface of PI film to form
PI copper plated filmCopper plating can be achieved through electrochemical copper plating or chemical copper plating methods. Electrochemical copper plating is the process of depositing a layer of copper film on the surface of a PI film using an electrolytic cell. Chemical copper plating is the process of depositing a layer of copper film on the surface of a PI film through a chemical reaction. Copper film can improve the conductivity and mechanical strength of PI film.
Post treatment: After the preparation of PI copper plated film is completed, post-treatment is required to improve its performance and stability. Post processing can include heat treatment, chemical treatment, etc. Among them, heat treatment is to anneal the PI copper plated film at high temperature to improve its heat resistance and stability. Chemical treatment is the use of chemical reactions to surface treat PI copper plated films, in order to improve their chemical stability and corrosion resistance.
