The name of the circuit board is: ceramic circuit board, alumina as a ceramic design circuit board, 1oz vs 2oz aluminum nitride has ceramic and circuit board, circuit board, PCB board, aluminum substrate, high-frequency board, thick copper plate, impedance board, PCB, ultra-thin electronic circuit board, ultra-thin circuit board, printed (copper etching treatment technology) circuit board, etc. The circuit board is the miniaturization and visualization of the circuit system, which plays an important role in the batch production of fixed control circuits and the optimization of the development layout of electrical appliances.
Printed circuit board (PCB) is an important part of modern electronic equipment, how to test a circuit board with a multimeter widely used in large machinery, personal computers, base stations or mobile phones, household appliances, electronic toys and other fields, but also widely used in printed circuit boards.
The printed circuit board is mainly composed of insulated substrate and conductor, which plays the role of support, interconnection and partial circuit components in electronic equipment. Integrated circuits and electronic components such as resistors and capacitors cannot function as a single individual. Only if there is a foothold on the printed circuit board, with a conductive junction connecting them, can it function in this whole. The printed circuit board is the skeleton that supports the components and the pipes that connect the electrical signals. In addition, some printed circuit boards are also equipped with resistors, capacitors, inductors and other components, which become functional circuits and play the role of gas pipes.
The functions of printed circuit boards in electronic equipment include: to provide fixed and assembled mechanical support for transistors, integrated circuits, resistors, capacitors, inductors and other components; Realize wiring, electrical connection and electrical insulation between transistors, integrated circuits, resistors, capacitors, inductors and other components to meet their electrical characteristics; Provide features and graphics for the inspection and maintenance of components in the electronic assembly process, and provide graphics for wave soldering.
Due to the use of printed circuit boards in electronic equipment, manual wiring errors are avoided, and automatic insertion, welding and detection are realized. Thus to ensure the quality and reliability of electronic machine products, improve labor productivity, reduce production costs, convenient maintenance.
