• PCB

• PCB printed circuit board, also known as printed circuit board, is an important electronic component, is the support of electronic components, is the carrier of electrical connection of electronic components. Almost every kind of electronic device has electronic components such as integrated circuits, so as to make the electrical interconnection between the components, it is suitable for printing. The printed circuit board has the dual function of conducting circuit and insulating floor.
• Classification: according to the number of circuit board layers can be divided into single panel, double panel, four-layer board, six-layer board and other multi-layer circuit board.

(1) Single panel: On the most basic PCB, the parts are concentrated on one side and the wires on the other side. because the wire only appears on one side.

(2) Double panel: This circuit board has wiring on both sides, but to use the wire on both sides, it is necessary to have a proper circuit connection between the two sides. A "bridge" between these circuits is called a guide hole (via). A guide hole is a small hole filled or coated with metal on a PCB, which can be connected to a wire on both sides.

(3) Multi-layer board: In order to increase the area that can be wired, the multilayer board uses more single or double-sided wiring boards. A printed circuit board with one double-sided inner layer, two single-sided outer layer or two double-sided printed circuit boards with two single-sided printed circuit boards with one side as inner layer and two single-sided printed circuit boards with one side as outer layer.

• Advantages: simplify the assembly and welding of electronic products, reduce the connection workload under the traditional mode, greatly reduce the labor strength of workers; reduce the volume of the whole machine, reduce the cost of products, improve the quality and reliability of electronic equipment; adopt standardized design, which is conducive to mechanization and automation in the production process; the whole assembly and commissioning PCB can be used as an independent spare part to facilitate the exchange and maintenance of the whole machine products.
