Copper plating on PET filmTechnical principles and advantages

PET (polyethylene terephthalate) film itself has excellent physical and chemical properties, such as good insulation, mechanical strength, and chemical corrosion resistance. Through copper plating process, a uniform copper layer is deposited on the surface of PET film, endowing it with new characteristics and functions. The preparation of PET copper plated film usually adopts the methods of chemical copper plating or electroplating copper. Chemical copper plating is the process of depositing copper on the surface of PET through chemical reduction reactions, without the need for external current, and can achieve uniform coating on complex shaped substrates; Electroplated copper is achieved through electrolysis, which reduces and deposits copper ions on the surface of the cathode (PET film), resulting in thicker coatings and higher production efficiency.

Compared with traditional copper foil materials, PET copper plated film has many significant advantages. Firstly, it has excellent flexibility and can bend and fold without affecting its performance, which makes it have great potential for applications in the field of flexible electronic devices, such as flexible displays and wearable devices. Secondly, PET copper plated film is lightweight, which greatly reduces the weight of the product compared to traditional copper based materials, in line with the development trend of modern electronic products becoming thinner and lighter. In addition, PET copper plated film also has good electromagnetic shielding performance, which can effectively block the interference of electromagnetic waves and ensure the normal operation of electronic devices.
