Zhuhai Preferred Copper Foil Processing
Most copper foils used for domestic printed boards are 35um thick, and 50um copper foils are used as transition products. In high-precision hole metallized double-sided or multilayer board manufacturing, thinner than 35um copper foils, such as 18um, 9um and 5um copper foils, are expected. Some multilayer boards use thicker copper foil, such as 70um.

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.

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.
Zhuhai Preferred Copper Foil Processing
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.
