Is PCB a printed circuit board

　　PCB board, also known as printed circuit board or printed circuit board in Chinese, is a support body for electronic components and a provider of electrical connections. ‌‌

　　PCB board is an indispensable component in electronic devices. It is produced through electronic printing technology, using an insulating substrate covered with conductive patterns and solder pads for assembling and soldering electronic components. The main function of PCB board is to fix and connect various electronic components, realizing the preset functions of the circuit. According to different structures, PCB boards can be divided into single panel, double-sided board, and multi-layer board. A single panel only has conductive patterns on one side, while a double panel has conductive patterns on both sides and is connected through vias. A multi-layer board has three or more layers of conductive patterns, which are laminated and interconnected to form a complex circuit network.

　　The invention and application of PCB boards have greatly promoted the development of the electronics industry, making electronic devices more compact and integrated. The design process involves the foundation of circuit schematics, which are implemented through computer-aided design software to optimize layout and connections, ensuring the performance and reliability of the circuit. With the continuous advancement of surface mount technology (SMT) and next-generation surface mount devices (SMD), the technology of PCB boards is also constantly innovating to meet the demands of more complex and high-performance electronic devices.
