What is the PCB used for?
摘要：There are many types of circuit boards with different names, which can be named according to materials, layers, inherent characteristics, etc., such as: single-sided, double-sided, multi-layer boards, HDI, allegro, FR4 circuit boards, ceramic circuits board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printing (copper engraving etch technology) circuit boards, etc. The circuit board is a miniaturized and intuitive circuit, which plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances.

Printed circuit board (PCB) is an indispensable accessory in modern electronic equipment. All electronic equipment, whether it is large machinery or personal computers, communication base stations or mobile phones, household appliances or electronic toys, will use printed circuit boards. .
The composition of printed circuit boards is mainly composed of two types of materials: insulating substrates and conductors, which play the role of support, interconnection and some circuit elements in electronic equipment. Integrated circuits and electronic components such as resistors and capacitors cannot function as a single individual. Only when they have a foothold on the printed circuit board and have lead junctions to connect them can they function as a whole. The printed circuit board is the skeleton that supports the components and the pipeline that connects the electrical signals. In addition, some printed circuit boards have components such as resistors, capacitors, and inductors attached to them, which become functional circuits and play the role of trachea.
The functions of printed circuit boards in electronic equipment include: providing mechanical support for fixing and assembling for transistors, integrated circuits, resistors, capacitors, inductors and other components; realizing transistors, integrated circuits, resistors, capacitors, inductors and other components The wiring, electrical connection and electrical insulation between them meet their electrical characteristics; identification characters and graphics are provided for the inspection and maintenance of components in the electronic assembly process, and solder resist graphics are provided for wave soldering.

In the whole electronic equipment, because the printed circuit board is used, the error of manual wiring is avoided, and automatic insertion, welding and detection are realized. Therefore, the quality and reliability of the electronic complete machine products are ensured, labor productivity is improved, production costs are reduced, and maintenance is facilitated.
