Chaozhou Preferred Copper Foil Processing
Definition of electrolytic copper foil: it is formed by depositing copper ions in electrolyte on the round cathode roller of smooth rotating stainless steel plate (or titanium plate). The surface close to the cathode roller is called smooth surface, and the other surface is called rough surface.

Copper foil can be divided into many kinds according to different classifications. According to the thickness, it can be divided into: thickness (more than 70 μ m) Regular thickness copper foil (more than 18 μ M but less than 70 μ m) Thin copper foil (more than 12 μ M but less than 18 μ m) Ultra thin copper foil (less than 12 μ m) Etc.

The production process of electrolytic copper foil is simple. There are three main processes: solution raw foil, surface treatment and product slitting. The production process seems simple, but it is a production process that integrates electronics, machinery and electrochemistry, and is particularly strict with the production environment. Therefore, the industry does not have a set of standard and universal production equipment and technology, and each manufacturer shows its own ingenuity, which is also an important bottleneck affecting the improvement of domestic production capacity and quality.

Copper foil is not a traditional metal copper product. It combines design concepts such as composite material and nano material technology, and different internal microstructures, resulting in different properties from traditional pure copper. The application of copper foil mainly focuses on the characteristics of conduction, heat conduction and electromagnetic wave shielding.
