355nm UV laser for automatic marking of QR code on PCB/FPCB surface

PCB circuit board has high wiring density, small size and light weight, which is conducive to the development of smart phone electronic equipment in the direction of high density, high integration, packaging, miniaturization and multilayer; especially the bending resistance of FPC flexible boards, Precision, better application to high-precision instruments of cameras, mobile phones, and video cameras.

In the production process of PCB and FPC circuit boards, drilling, cutting, and engraving of traceable QR codes are required. How is this achieved?

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 13 years of technical strength accumulation, the power of RFH UV lasers has been increased from 3W-5W to 8W, 10W, and 15W to meet market development needs. The substantial increase in power has doubled the processing performance. Next, the RFH Laser Editor will introduce to you how powerful a 15W UV laser is. Take our Expert III 355 ultraviolet pulsed solid-state laser as an example:

The Expert III 355 series ultraviolet laser with a power of 15W can quickly cut, scribe, perforate PE, PCB, FPC, glass, sapphire, ceramics and other non-metallic materials, and can achieve ultra-fine processing effects, such as not burning Edge, non-carbonization, low thermal effect, and unique Q-switching control technology, which can be suitable for various laser application control needs, so it is evaluated as a "high-precision laser processing master" by domestic and foreign industry users!

The excellence of this RFH laser comes from many aspects:

1. Rigorous production management system. From procurement to production and assembly, finished product testing, to warehousing quality inspection, pre-delivery inspection, and after-sales service, each level is checked to ensure stable quality and consistency of equipment parameters with actual operating parameters;

2. First-class technical support. The RFH R&D team is composed of professors and doctors at home and abroad. It has independently developed technologies such as intelligent power control, which can update the functional modules of the power control system in time, and improve the functional modules according to the needs of the laser to ensure the stability of the laser. At the same time, RFH Expert III 355 series ultraviolet lasers also have an internal cavity self-purification system, which makes the laser long life and stable operation. Adopting unique laser cavity design and integrated design, small size and high integration.

13 years of deep cultivation, RFH has made fruitful results. The team has obtained 10 national patent certificates, 14 computer software work certificates, and won the "National High-tech Enterprise", "Shenzhen High-tech Enterprise", "Software Enterprise Certification Certificate" and other certificates. It has won high recognition and good reputation from users in all walks of life at home and abroad, and has established an excellent brand image in the nanosecond laser industry.
