[0002] A PCB board, namely a printed circuit board, is an indispensable key component in modern electronic devices. It is a carrier of electronic components formed by processing a conductive pattern (such as a copper foil circuit) and connection points (such as pads, vias, etc.) on an insulating substrate (usually an organic resin material, such as glass fiber reinforced epoxy resin) through a specific process. The main function of the PCB board is to achieve electrical connection and mechanical support between electronic components, thereby constituting a complete circuit system. With the continuous development of electronic technology, the design and manufacturing technology of PCB boards are also constantly progressing. Modern PCB board manufacturing technology has achieved high automation and intelligence, greatly improving production efficiency and product quality.
