Laser marking on circuit boards uses high-precision laser beams to permanently etch information on the board, solder mask layer, or copper foil, which is a key step in achieving product traceability and quality management. Within its markingsContent usually includes core data such as component tag number, version number, unique serial number, QR code, and brand identification. This non-contact processing method avoids mechanical stress and chemical pollution, with clear and wear-resistant markings that can withstand harsh environments such as welding, cleaning, and high temperature and humidity. It ensures the readability and reliability of information throughout the entire product lifecycle, providing a solid data foundation for production process control, anti-counterfeiting traceability, and after-sales service.
