Surface treatment of rolled copper foil

Surface treatment of copper foil involves roughening one side of high-precision copper foil to increase the peel strength of the metal material. The surface of the roughened copper foil has a frosted texture, making it easier to laminate with other materials and less prone to detachment. There are two mainstream treatment methods currently available. One is called reddening treatment, which mainly consists of copper powder and results in a red surface color after treatment; Another type is blackening treatment, mainly composed of cobalt and nickel powder, and the surface color after treatment is black. The post-treatment copper foil produced by Advanced Institute Technology has the characteristics of stable thickness tolerance, no powder loss on the roughened surface, and good uniformity of copper sprouts. At the same time, Advanced Institute Technology also conducts high-temperature antioxidant treatment on the smooth surface of the roughened foil during production to prevent the material from discoloration at high temperatures during customer processing. This type of copper foil is produced and packaged in a Class 10000 dust-free workshop to ensure the cleanliness of the material and is more suitable for high-end electronic material processing. Advanced Institute Technology Co., Ltd. can also customize production according to customer requirements to better meet their demands for high-end materials.
