What exactly is the PCB board used for? You will understand everything after reading this

There are many types of circuit boards with different names. They can be named according to materials, number of layers, inherent characteristics, etc., such as: single-sided, double-sided, multilayer, HDI, Allegro, FR4 circuit board, ceramic circuit PCB, 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 engraved Corrosion 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 optimizing the layout of electrical appliances.

PCB circuit board

Printed circuit board (PCB circuit board) is an indispensable accessory in modern electronic equipment. Printed circuit boards are used in all electronic equipment, whether it is large machinery or personal computers, communication base stations or mobile phones, household appliances or electronic toys. .

The printed circuit board is mainly composed of two types of materials: insulating base material and conductor, which play the role of support, interconnection and part of the circuit components in electronic equipment. Electronic components such as integrated circuits, resistors, capacitors, etc. cannot function as a single entity. Only when they have a foothold on the printed circuit board and have a conductive junction to connect them, can they perform their functions in the whole. The printed circuit board is the skeleton supporting the components and the pipeline connecting the electrical signals. In addition, some printed PCB circuit boards have components such as resistors, capacitors, and inductors attached to them, which become functional circuits and serve as air pipes.

The role of the printed circuit board in the electronic equipment is: to provide fixed and assembled mechanical support for transistors, integrated circuits, resistors, capacitors, inductors and other components; to realize transistors, integrated circuits, resistors, capacitors, inductors and other components The wiring and electrical connection and electrical insulation between the components meet its electrical characteristics; it provides identification characters and graphics for the inspection and maintenance of components in the electronic assembly process, and provides solder mask graphics for wave soldering.

As the printed circuit board is used in the electronic equipment, manual wiring errors are avoided, and automatic insertion, welding and detection are realized. So as to ensure the quality and reliability of the electronic product, it also improves labor productivity, reduces production costs, and facilitates maintenance.
