Excellent tensile strength and elongation High tensile strength and elongation under normal conditions can improve processing ability, enhance rigidity and avoid wrinkles to improve production qualification rate. High temperature extensibility (THE) copper foil and high tensile strength copper foil at high temperature can improve the thermal stability of printed boards and avoid deformation and warpage.

According to the burning degree of the substrate in the flame and after leaving the ignition source, it can be divided into general type and self extinguishing type; According to the bending degree of the substrate, it can be divided into rigid and flexible laminates; According to the working temperature and working environment conditions of the substrate, it can be divided into heat resistant, radiation resistant, high-frequency foil clad plate, etc. In addition, there are also laminates used in special occasions, such as prefabricated inner laminates, metal based laminates, and copper foil, nickel foil, silver foil, aluminum foil, Kang copper foil, beryllium copper foil laminates according to the type of foil.

The electrolyte contains oil, paint, grease, sediment and other contaminants attached to the surface of copper foil. After being squeezed by the squeezing (water) roller, the contaminants are squeezed flat, some contaminants attach to it, and some contaminants attach to the guide roller. Because the dirt is squeezed up during the operation, the dirt has a head and a tail, and has a direction.

Electronic circuit copper foil plays an important role in conducting electricity and heat in printed circuit board (PCB), and is known as the neural network on PCB. At present, copper foil for electronic circuits (PCB copper foil) is divided into two categories, namely conventional copper foil and high-performance copper foil.
