What material does PCB have?
There are many kinds of copper clad laminates. According to different material can be divided into paper substrate, glass cloth substrate and synthetic fiber board; according to the different binder resin is divided into phenolic, epoxy, polyester and polytetrafluoroethylene; use can be divided into general and special type.
The surface of the substrate is covered with a layer of high conductivity, good welding of pure copper foil, commonly used thickness of 35 ~ 50 / Ma; copper foil covered in copper clad laminate substrate side called single copper, copper clad laminate substrate on both sides covered with copper foil called double-sided copper clad laminate; copper foil can securely covered on the substrate. The adhesive to complete. Commonly used CCL thickness of 1.0mm, 1.5mm and 2.0mm three.
The main material of printed circuit board (PCB) is copper clad laminate, and copper clad laminate is made up of base plate, copper foil and adhesive. The base plate is an insulating plywood made of macromolecule synthetic resin and reinforcing material;
