The copper foil industry belongs to the copper processing industry, which processes copper into extremely thin copper strips or sheets by means of rolling, electrolysis and sputtering, and further applies them as industrial raw materials in various downstream products. The thickness of μ Below m, the thickness varies depending on the scene used.

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.

Calendered copper foil is the original foil made from copper plate by repeated rolling, and then roughened according to requirements. Due to the limitation of processing technology, its width is difficult to meet the requirements of rigid copper clad laminate, so calendered copper foil is rarely used on rigid copper clad laminate; However, because the bending resistance and elastic coefficient are greater than electrolytic copper foil, they are often used on flexible copper clad laminate.

The commonly used reinforcement materials of copper clad laminate are alkali free (alkali metal oxide content shall not exceed 0.5%) glass fiber products (such as glass cloth, glass felt) or paper (such as wood pulp paper, bleached wood pulp paper, cotton wool paper). Therefore, laminates can be divided into glass cloth base and paper base.
