The high-power nanosecond ultraviolet laser engraves the marking code on PCB circuit board without falling off

PCB circuit board drilling, cutting, and engraving require a cold light source UV laser

Ultraviolet laser assists PCB circuit board drilling, cutting, engraving and traceability QR code

How to drill, cut, and engrave traceable QR codes on PCB?

This requires understanding of RFH UV laser technology.

Ultraviolet laser has a wavelength of 355nm, which is a cold light source. The heat affected zone of laser cutting is particularly small as 10μm and will not produce thermal effects. Therefore, when drilling, cutting and engraving high-precision and high-level PCB circuit boards, no burrs will be produced , and it will also not causes deformation or scorching problems. UV laser are better than CO2 and fiber lasers.

In the past 13 years of hard work, RFH Expert II 355nm UV lasers have fully penetrated into all aspects of the 3C industry, especially in the field of PCB and FPC flexible circuit board marking, which has established a good brand image.

RFH Expert II 355nm UV laser has a wide range of repetition frequency (single pulse to 200kHz), it can be absorbed by the material, and has little destructiveness to the material, sterile 0 pollution, the identification code does not fall off, and the writing is clear and easy to identify. It Very suitable for marking high-density circuit boards.
