1. Printed circuit board (PCB) is an indispensable component in the electronics industry, serving as the mounting substrate for electronic components and the bridge for electrical connections. PCB is manufactured through electronic printing technology, hence its name.
2. The role of PCB is crucial: after applying PCB in electronic devices, the consistency of PCB can reduce the possibility of manual wiring errors. In addition, PCBs support automatic assembly, soldering, and testing of electronic components, ensuring product quality, improving production efficiency, reducing costs, and simplifying maintenance processes.
3. Classification of PCBs: According to the number of layers, PCBs are mainly divided into single panel, double-sided board, and multi-layer board.
-Single sided: Components and wires are concentrated on one side, suitable for simple electronic devices.
-Double sided board: Components and wires are distributed in two layers and connected between layers through vias, suitable for more complex electronic products.
-Multilayer board: A type of PCB commonly used in modern electronic devices, which has three or more conductive layers and insulation layers, and forms complex circuit structures through lamination and interconnection.
4. In addition, PCBs can also be classified according to their characteristics, including flexible boards (FPC), rigid boards (PCB), and soft hard bonding boards (FPCB), each of which is suitable for different design and application requirements.
