PET COMPOSITE COPPER FOIL MARKET SEGMENTATION

By Type

Based on Type, the global market can be categorized into 6µm, Above 6µm.

6µm: 6µm PET Composite Copper Foil is thin copper foil that measures merely 6 micrometers thickness, laminated by a film of PET film. This is typically used for high-density and small-sized electronic applications, e.g., FPCBs, cellular phones, and wearable technologies. The advantage of 6µm foil is that it supports fine trace patterns and tight designs, which are necessary for electronic device miniaturization. Though it possesses higher flexibility and superior performance, its production requires advanced technology to ensure uniformity and precise thickness control. The 6µm foil industry is growing rapidly because of growing demand for miniature and high-performing electronic elements, especially from consumer electronics as well as from the automotive market.
Above 6µm: Over 6µm PET Composite Copper Foil is copper foil greater than 6 micrometers thickness, like 9µm and 18µm or higher. These foils are used for applications requiring improved conductivity and mechanical strength, including power electronics, automotive applications, and large electronics. They possess improved durability and are less susceptible to damage during handling and installation compared to thinner copper foils. The foregoing 6µm foil industry is steady since they are utilized in heavier and industrial applications where more copper thickness is needed in order to pass higher currents and offer long-lasting performance. The demand is steady but is in danger from other materials that can perform equally well but at less cost, therefore cost-effectiveness is a chief determinant of its application.
