Ultraviolet laser drilling, cutting, and engraving QR codes on PCB circuit boards

 

PCB circuit boards are used in almost all electronic products and are considered the "mother of electronic systems". At present, PCBs are mainly used in electronic products such as household appliances, PCs, and smart phones.

Smart phone functions are becoming more and more complex and the volume is becoming lighter and thinner, leaving less and less space for the motherboard, requiring more components on the limited PCB motherboard, and ordinary multi-layer boards have been unable to meet the demand. The high-density interconnect circuit board (HDI) adopts the build-up method to make the board. The ordinary multi-layer board is used as the core board to superpose the build-up layer. The process of drilling and metalization in the hole enables the interconnection function between the various layers of circuits and saves PCB can be routed area, greatly increase the density of components, so the replacement of multi-layer boards in smart phones is quickly completed.

 

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

 

This requires understanding of RFH ultraviolet 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 there is no heat effect. Therefore, when drilling, cutting, and engraving high-precision and high-level PCB circuit boards, there will be no burrs. , Deformation or scorching problems, this is CO2, fiber lasers cannot match.

 

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

 

RFH Expert Ⅱ 355nm UV laser has a wide range of repetition frequency (single pulse to 200kHz), can be absorbed by the material, and is less destructive to the material, sterile 0 pollution, the identification code does not fall off, the handwriting is clear and easy to identify, which is very suitable Mark high-density circuit boards.

 

At the same time, it has superior beam quality (M2<1.2), which is strictly guaranteed in all frequency ranges; pulse width <20ns@30k, the heat-affected area during processing is small, and it supports digital intelligent power control, simple operation, and low hands-on cost , To meet the rapid mass production needs of enterprises.

 

In terms of production, RFH has a rigorous quality management system mechanism, from purchasing-pre-production quality inspection control-rigorous assembly process-finished product testing-warehousing quality inspection-pre-delivery inspection-after-sales service, all levels of control to ensure stable quality And the equipment parameters are consistent with the actual operating parameters. This is the reason why the service life of RFH brand lasers is better than that of peers.

 

In addition, RFH has the advantages of independent research and development of laser power technology, which can update the power control system functional modules in time, and improve the functional modules according to laser requirements.

 

At present, RFH Laser has a global industrial laser research and development team composed of professors, experts, and doctors at home and abroad. At the same time, it has established an application process research and development department, a laser research and development department, and an electrical research and development department. This laser product can maintain consistent stable quality, constant beam quality, high-efficiency power consumption characteristics under extreme industrial and scientific research conditions, and win the trust of users from all walks of life with its superior cost performance and high reliability.
