PCB (Printed Circuit Board) is the motherboard of electronic products. The function of PCB is to provide a base for connecting constructed components with other necessary electronic circuit parts to form a module or finished product with specific functions. Therefore, PCB plays the role of integrating all functions of the connecting assembly in the entire electronic product.
The base plate of printed circuit board is generally made of materials that are insulated, heat insulated and not easy to bend. The small circuit material visible on the surface is copper foil. Originally, the copper foil was covered on the whole board, but part of the copper foil was etched during the manufacturing process, and the remaining copper foil became a grid like small circuit. These circuits are called conductors and are used to provide circuit connections for components on the printed circuit board.In order to fix components on the printed circuit board, pins can be directly soldered on the bonding pad. The bonding pad is used to fix the pins of components or lead out wires, test lines, etc. The bonding pad has a variety of shapes, such as round, rectangular, etc.
The role of printed circuit board in electronic equipment is 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 It provides identification characters and graphics for inspection and maintenance of components in electronic assembly process, and provides resistance welding graphics for wave soldering.
The rapid development and widespread use of integrated circuits, so that the size of electronic equipment is becoming smaller and smaller, circuit wiring density and increasing difficulty, which requires the PCB to be updated. At present, a variety of PCBs has been developed from (Single-sided PCB)1 layer PCB to double-sided PCB (2 layers PCB), multilayer PCB board, flexible PCB, and Rigid-Flex PCB. In professional PCB manufacturers, mechanized and automated fabrication has reduced the manufacturing cost of PCB.
The role of printed circuit board in electronic equipment includes: providing 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; It provides identification characters and graphics for inspection and maintenance of components in electronic assembly process, and provides resistance welding graphics for wave soldering.
PCB – Printed circuit board is one of the important components in electronic industry. Almost every kind of electronic equipment, ranging from electronic watches and calculators to computers, communication electronic equipment and military weapon systems, as long as there are integrated circuits and other electronic components, must use printed boards for electrical interconnection. In the research process of large-scale electronic products, the most basic success factor is the design, documentation and manufacturing of the product’s printed board. The design and manufacturing quality of PCB directly affects the quality and cost of the whole product, and even affects the success or failure of commercial competition.
