[0002] PCB is the abbreviation of Printed Circuit Board. It is an important electronic component. It is the support of electronic components and the carrier of electrical connection of electronic components. The main function of PCB is to connect various electronic parts to form a predetermined circuit. Almost every electronic device, from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, must use PCB boards for the electrical interconnection between them. Due to its wide application, it is also known as the "mother of electronic products."
