PCB is in English (Printed Circuit Board) printed PCB, circuit board short. Usually in the insulation material on the predetermined design, made of printed circuits, printed components, or both a combination of graphics known as printed circuit conductive. In the insulating substrate to provide electrical connections between the conductive component graphics, known as the printed circuit. This put printed circuit or printed circuit board called the finished PCB, also known as PCB or printed circuit board. Circuit board according to the functions can be divided into to categories: single-sided PCB, double-sided circuit board, multilayer circuit board, aluminum board, impedance circuit boards, FPC flexible circuit board, etc., circuit board materials are divided into: Glass fiber, CEM-1, CEM3, FR4, kind of source material can be seen in our daily lives, such as fireproof cloth, fire blanket core is glass fiber, glass fiber and resin is easy to combine, we have compact structure and high strength The glass cloth dipped in resin, heat hardening on the insulation has been difficult to bend the PCB substrate - and if the PCB board break, white layer edge is enough to prove that the material is fiberglass resin.
