PCB board is the abbreviation of Printed Circuit Board. The Chinese name is printed circuit board , also known as printed circuit board and printed It is an important electronic component, a support body for electronic components, and a supplier of electrical connections for electronic components. , Because it is made of electronic printing, it is also called printed circuit board. A circuit board is simply a board on which integrated circuits and other electronic components .

Double-sided circuit board

　　According to the substrate classification: flexible circuit boards, rigid circuit boards and rigid-flex boards.

　　1. Flexible PCB board (flexible board)Double-sided circuit board

　　The flexible board is a printed circuit board made of a flexible substrate. Its advantage is that it can be bent, which is convenient for the assembly of electrical components. FPC has been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDA, digital cameras and other fields or products.

　　2. Rigid PCB board

　　It is made of paper base (usually used for single side) or glass cloth base (usually used for double-sided and multi-layer), pre-impregnated phenolic or epoxy resin, one or both sides of the surface layer is pasted with copper-clad foil and then laminated and cured. This PCB copper clad sheet is called a rigid board. After making a PCB, we call it a rigid PCB. A rigid board is a printed circuit board made of a rigid substrate that is not easy to bend and has a certain strength and toughness. Its advantage is that it can provide certain support for the electronic components attached to it. .

　　3. Rigid-flex PCB board (rigid-flex board)

　　Rigid-flex board refers to a printed circuit board containing one or more rigid areas and flexible areas, which are composed of rigid boards and flexible boards laminated together. The advantage of the rigid-flex board is that it can not only provide the support of the rigid printing board, but also has the tortuous characteristics of the flexible board, which can meet the needs of three-dimensional assembly.
