[0002] A printed circuit board (PCB) is a carrier manufactured based on an insulating substrate (such as epoxy resin, phenolic paper, or glass cloth). Conductive copper foil patterns (printed circuits) are formed on its surface through a predetermined design, and pads, vias, and other structures are provided to fix and connect electronic components, achieving electrical interconnection and mechanical support. It enables signal transmission between components through wires and vias, while providing solder mask protection for the circuitry. It features high density and high reliability, and is widely used in almost all electronic devices, including computers, communication equipment, and home appliances.
