Introduction to PCB

PCB (printed circuit board) is a printed circuit board, abbreviated as a printed circuit board, which is one of the important parts of the electronics industry. Almost every kind of electronic equipment, from electronic watches, calculators, to computers, communication electronic equipment, military weapon systems, as long as there are electronic components such as integrated circuits, in order to make the electrical interconnection between the various components must use PCB. The PCB is composed of an insulating bottom plate, connecting wires and pads for assembling and soldering electronic components, and has the dual functions of conductive lines and insulating bottom plates. PCB can replace complex wiring and realize the electrical connection between the components in the circuit, which not only simplifies the assembly and soldering of electronic products, reduces the workload of wiring in the traditional way, and greatly reduces the labor intensity of workers; it also reduces the overall machine Volume, reduce product cost, and improve the quality and reliability of electronic equipment.
