Printed circuit board (PCB) will appear in almost every electronic device. If there are electronic parts in a specific device, they are all mounted on PCBs of different sizes. In addition to fixing various small amounts, the primary function of the PCB is to provide electrical connections between the upper parts. As electronic devices become more and more complex, more and more features are needed, and the circuits and elements on the PCB are becoming denser and denser.
PCB is the abbreviation of Printed Circuit Board, translated into Chinese is called printed circuit board. Because it is made by electronic printing, it is called a "printed" circuit board. PCB instrument is an essential electronic component in the electronics industry, support for electronic components, and a carrier for electrical connection of electronic components.
PCB telecommunication has been extremely widely used in electronic products. The reason why it can be widely used, its unique characteristics are summarized as follows.
1. The wiring density is high, the volume is small, and the weight is light, conducive to the miniaturization of electronic equipment.
2. Due to the repeatability and consistency of the graphics, it reduces wiring and assembly errors and saves equipment maintenance, debugging, and inspection time.
3. PCB circuit board material is conducive to mechanized and automated production, improves labor productivity, and reduces the cost of electronic equipment.
4. The design can be standardized to facilitate interchangeability.
