High-power UV laser is used for drilling QR codes on PCB copper-clad boards without burrs

To print a QR code on the PCB copper clad board, you need it: UV laser

For various PCB and FPC materials with different functions and forms, UV lasers are undoubtedly the best choice. From the production of the most basic circuit boards, circuit wiring to pocket embedded chips, etc., more advanced processes can pass UV lasers. to fulfill. And now, it is still possible to punch QR codes on the small PCB copper-aluminum board

The high precision that RFH UV laser can achieve

At a recent large-scale laser technology expo, RFH UV laser has attracted the attention of many people, not only because the UV laser produced by RFH can mark on the basis of increasing material flexibility, but also because RFH UV laser The smallest precision that can be achieved. First of all, RFH UV laser can eliminate some unnecessary mechanical stress in machining and avoid material damage or deformation when cutting.

355nm UV laser perforates the PCB copper clad board to avoid scorching or deformation

Secondly, because it uses the camera for positioning, it can also reach the level of rapid cutting, and it can be formed at one time without opening the mold. In addition, the UV laser marker is a machine that uses cold-light laser for marking. Because of its small precision focused light source and small processing heat-affected zone, it will not produce thermal effects and material scorching problems, and it perfectly avoids heat. Processing damage to materials, reduce material damage, and reduce production costs. Improve processing quality. The precision of the two-dimensional code is very important, and RFH can mark with the minimum accuracy of 0.02mm, which plays a role in the small size of the PCB copper clad board.

Nanosecond laser marking PCB and FPC materials

RFH participation in the exhibition not only made its own reputation, but also represented a group of domestic laser technology research and development leading technologies, but RFH will not stop here, but will continue to advance with the goal of leading domestic and foreign levels.
