PCB board is the abbreviation of Printed Circuit Board. The Chinese name is printed circuit board, also known as printed circuit board, printed circuit board. It is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components , Because it is made by electronic printing, it is also called a printed circuit board. Simply put, a circuit board is a board with integrated circuits and other electronic components.

Circuit board classification knowledge

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



1. Flexible PCB board  Flexible board is a printed circuit board made of flexible substrates. Its advantage is that it can be bent and facilitates the assembly of electrical components. FPC has been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDAs, digital cameras and other fields or products.



2. Rigid PCB board  Is made of paper base (usually used for single-sided) or glass cloth base (usually used for double-sided and multilayer), pre-impregnated with phenolic or epoxy resin, one or both sides of the surface layer are glued with copper foil and then laminated and cured. This kind of PCB copper clad board, we call it rigid board. Then make PCB, we call it rigid PCB. A rigid board is a printed circuit board made of a rigid base material that is not easy to bend and has a certain degree of toughness. Its advantage is that it can provide a certain support for the electronic components attached to it. .



3. Rigid-flex PCB board  "Rigid-flex board" refers to a printed circuit board that contains one or more rigid areas and flexible areas, which is composed of a rigid board and a flexible board laminated together. The advantage of the rigid-flex board is that it can not only provide the supporting function of the rigid printed board, but also has the bending characteristics of the flexible board, which can meet the needs of three-dimensional assembly.
