PCB (Printed Circuit Board), the Chinese name for printed circuit board, also known as printed circuit board, is an important electronic
component. It is the support of electronic components and the carrier of the electrical connection of electronic components. Since it is made using electronic printing, it is called a "printed" circuit board.
A printed circuit board (PCB) is a thin sheet made of an insulating material such as fibreglass or epoxy resin that is etched or printed with a conductive path on its surface. These paths, also known as traces, are typically made of copper and are used as electrical connections between various electronic components such as resistors, capacitors, and integrated circuits. The primary function of a PCB is to provide a stable and organized platform for mounting and interconnecting these circuit components, enabling them to work together to perform specific tasks within an electronic device.
Its main function is to connect various electronic components through the circuit, play the role of conduction and transmission, and is the key electronic interconnection of electronic products. Almost every electronic device is inseparable from the printed circuit board because it provides mechanical support for the fixed assembly of various electronic components, realizes the wiring and electrical connection or electrical insulation between them, and provides the required electrical characteristics. Its manufacturing quality directly affects the stability and service life of electronic products, affects the overall competitiveness of system products, and is known as the "mother of electronic products.".
