With the rapid development of electronics manufacturing technology, portable electronic products are increasingly developed in the direction of miniaturization, high integration and lightness. In addition, the development of packaging technology, the pads and spacings are getting smaller and smaller, making printed alignment more difficult. The laser marking machine is marked with its accuracy, flexibility, can overcome the easy-off and removal of screen printing, and the technical defects of processing precision will play a pivotal role in the PCB board industry!
How to implement the quality control of the PCB, which requires the product quality traceability system. Generally, by laser marking technology, in the PCB board, the radium carving string, one-dimensional code, QR code, etc. Source supplier information to the product outbound data tracking, full tracking, greatly enhance product quality, and realize the management of product automation production.
Early, strings on the surface of the PCB, images, contact information, two-dimensional code and other information are inkjet. As the electronic equipment is thin, the development of miniaturization, the formation of the PCB board is small, in order to save space utilization, the two-dimensional code marked on the PCB board is small, high density, small high-density The tag of the code can only be achieved by the laser marking machine. Compared with the inkjet, the laser marking technology is more environmentally friendly, the economy, the long-term mark will not be easily removed, non-contactless non-destructive marking, does not hurt the substrate, high processing accuracy, service life Long, fast processing efficiency, beautiful tag, hand touch has no obvious touch, manual operation, fool processing.
PCB QR code markers and laser technology combined, laser marking technology helps the PCB board industry to complete quality control, and the broad PCB market provides broad development space for laser marking machine industries.
