CB (Printed circuit board) is the most common name, it can also be called "printed wiring boards" or "printed wiring cards". Before the advent of PCBs, circuits were made up of point-to-point wiring. The reliability of this method is very low, because as the circuit ages, the rupture of the line can lead to the open circuit or short circuit of the line node.
1. PCB board is a printed circuit board, also known as a printed circuit board, which is the provider of electrical connections for electronic components. The circuit is used as a tool for conduction between the originals. In the design, a large copper surface will be designed as a grounding and power supply layer. Lines and drawings are made at the same time. The wiring density is high, the volume is small, and the weight is light, which is conducive to the miniaturization of electronic equipment.
2. The base plate of the board itself is made of insulating materials that are not easy to bend. The thin circuit material that can be seen on the surface is copper foil. Originally, the copper foil covered the entire board, but part of it was etched away during the manufacturing process, and the remaining part became a mesh-like thin circuit. .
3. PCBs vary according to their substrate materials. High-frequency microwave boards, metal substrates, aluminum substrates, iron substrates, copper substrates, double-sided and multi-layered boards. PCB is the abbreviation of Printed Circuit Board in English, and the Chinese name is printed circuit. Board, also known as printed circuit board, printed circuit board, is an important electronic component.
