PCB (printed circuit board) is printed circuit board which is one of the important components in the electronics industry. Almost every kind of electronic equipment, from electronic watches and calculators to computers, communication electronic equipment and military weapon systems, as long as there are electronic components such as integrated circuits, in order to make the electrical interconnection between various components, we must use printed board.
The printed circuit board 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 plate.
It can replace the complicated wiring and realize the electrical connection between the components in the circuit:
- Simplifies the assembly and welding of electronic products,
- reduces the wiring workload in the traditional way,
- greatly reduces the labor intensity of workers;
- reduces the overall machine Volume,
- reduce product cost,
- improve the quality and reliability of electronic equipment.
The printed circuit board has excellent product consistency, it can adopt standardized design, which is easy to mechanization and automation in the production process. At the same time, the entire printed circuit board after assembly and debugging can be used as an independent spare part, which is convenient for the exchange and maintenance of the whole product.
At present, printed circuit boards have been extremely widely used in the manufacture of electronic products
