Analysis of the advantages of conductivity and thermal conductivity of PP copper plated film

PP copper plated film combines the lightweight and flexibility of plastic substrates with the high conductivity and good heat dissipation performance of metal coatings, making it an ideal composite material. It is not only suitable for traditional electronic products, but also plays an important role in emerging technologies such as 5G communication and IoT devices. This article aims to provide an in-depth analysisPP copper plated filmThe advantages of conductivity and thermal conductivity provide reference for the research and application of related industries.

Efficient conductive pathway

Copper, as an excellent conductor, has a resistivity as low as 1.68 × 10 ^ -8 Ω· m, far lower than most other commonly used metals. When the surface of PP is uniformly covered with a thin and dense copper film, the entire structure forms an efficient current transmission channel, greatly improving the overall conductivity of the material. In addition, by optimizing the copper plating process, the interface contact resistance can be further reduced, ensuring more stable and reliable signal transmission.

Electromagnetic shielding effectiveness

In addition to its basic conductive function,PP copper plated filmIt also exhibits excellent electromagnetic shielding performance. Due to the excellent ability of copper to reflect and absorb electromagnetic waves, this composite material can effectively block the influence of external interference sources on internal circuits, while preventing internal radiation leakage, which is particularly important for sensitive electronic components.

Good heat dissipation effect

PP itself is a thermal insulation material, but adding a copper coating on its surface greatly enhances the material's thermal conductivity efficiency. The thermal conductivity of copper is 401 W/(m · K), which enables PP copper plating film to quickly transfer heat from high temperature areas to low temperature areas in a short period of time, thereby achieving the goal of rapid cooling. This characteristic is crucial for electronic components that require long-term operation in high-temperature environments.

Temperature Stability

Thanks to the excellent thermal conductivity of copper, PP copper plated film can maintain stable mechanical and electrical properties over a wide temperature range. Even under extreme conditions, the material will not deform or fail due to excessive temperature differences, ensuring the long-term reliability of the product.
