Plastic Computer PC copper silver aluminum film is a commonly used PCB (Printed Circuit Board) process

PC (Plastic Computer) copper silver aluminum film is a commonly used PCB (Printed Circuit Board) process, used to form a corrosion-resistant and high-temperature resistant copper silver film on the surface of the PCB. The key technology of PC copper silver aluminum film is:
1. Choose high-quality copper silver film materials. Due to the high corrosion resistance and temperature resistance of copper silver film, strict control should be exercised when selecting copper silver film materials.
2. Reasonably design PCB technology. In the PC copper silver aluminum film process, attention should be paid to avoiding excessive or insufficient thickness of the film layer to ensure its corrosion resistance and temperature resistance.
3. Improve the level of PCB surface treatment technology. In the PC copper silver aluminum film process, it is necessary to improve the surface treatment level of the PCB to enhance the corrosion resistance and temperature resistance of the film layer.
4. Strengthen production management. In the PC copper silver aluminum film process, it is necessary to strengthen production management to ensure that the quality and output of the film layer meet the requirements, in order to ensure product quality and stability.
5. Strengthen production monitoring and inspection. In the PC copper silver aluminum film process, it is necessary to strengthen production monitoring and inspection to ensure the normal progress of the production process and stable product quality.

PC copper plated silver aluminum filmThe preparation methods mainly include physical vapor deposition (PVD) and chemical vapor deposition (CVD). Among them, PVD method uses high-energy electron beams or ion beams to evaporate or sputter metal materials onto substrates, forming thin films. The CVD method uses chemical reactions to decompose gaseous precursors and deposit them on the substrate surface to form a thin film. Both methods have their own advantages and disadvantages. The film layer prepared by PVD method is denser and has a uniform structure, but the production efficiency is low; The CVD method has high production efficiency and good adaptability to substrates with complex shapes, but the quality of the film layer is relatively poor. Therefore, choosing different preparation methods needs to be considered based on specific application requirements.
