FPC QR code laser marking system helps companies complete product traceability

Today, the electronic industry is changing with each passing day, and various fully functional smart products are emerging in an endless stream. Among them, PCB occupies a considerable area. It is the main component of the circuit board of electronic products. The link continues to extend to various regions. The demand for PCB is more vigorous than ever. Therefore, during the processing process, a large number of parts need to be supervised. The laser marking machine provides a traceability system QR code function to help the PCB processing field to achieve control.

The QR code mark on the PCB adopts a laser processing technology. It is different from other processing methods. It has significantly improved in cost control, quality monitoring, working speed, etc. The traditional processing method cannot achieve the QR code mark of PCB. The reason is that the contact processing will cause damage to the PCB surface while processing the PCB, which will cause the failure of the electronic product. Moreover, the traditional processing method cannot be so fine. We all know that the PCB components are assembled on the equipment, and the PCB is a thin object. In this case, the processed pattern is not only not clear enough, but also falls off over time.

The laser targets precision parts. The PCB QR code laser marking machine uses a processing method called UV laser marking machine. The size of this processing method is generally not too large, ranging from 3-3mm to -1.2-1.2mm. This processing method uses a processing method called UV laser marking machine, which is the so-called cold light source processing method, that is, the light source of the laser marking machine is low temperature or even temperatureless, which helps to not damage the PCB itself when marking the PCB with a QR code. Because it is low temperature, compared with ultraviolet laser, the light source power of this laser light source is much smaller (there is also high power). Low power does not mean low efficiency and precision. This is because the focused light source is relatively concentrated. When performing precision processing on small parts, the marked pattern looks relatively stable and will not change over time.

The ultraviolet laser marking machine used in the PCB processing field is calledPCB QR code marking machine, it can automatically complete PCBQLR marking while maintaining work efficiency, saving labor costs, and can also play the role of tracing process system, which is well integrated into the production line of the enterprise, and the results can be known immediately when problematic parts are found.
