PCB circuit board is marked with 355nm ultraviolet laser and is not easy to deform and burn


Ultraviolet laser has a wavelength of 355nm, which is a cold light source and has a particularly small thermal impact. It is more suitable for deep processing of materials that are more sensitive to thermal effects. It is not easy to deform or burn. Therefore, UV lasers have an unshakable position in plastic marking.

In addition, the focused spot of the UV laser is 15um, which is very suitable for micro-hole drilling. No, today I met a customer from Shanghai who was going to purchase a 3W or 5W UV laser for PCB circuit board engraving and drilling.


Because the customer is located in Shanghai, it is not convenient for the company to participate. We conducted a video conversation and took the customer to visit the UV laser dust-free production workshop through the video lens, and introduced RFH from procurement-quality control before production-rigorous assembly process -Finished product testing-warehousing quality inspection-pre-delivery testing-after-sales service, a quality production system that is strictly controlled. There is also an introduction to the laser dedicated power control system independently developed by RFH. As we all know, there is a one-to-one correspondence between the power supply and the laser. The stability of the power control system determines whether the laser can maximize its performance during operation. RFH has the advantages of independent research and development of power supply technology, which can update the function modules of the power control system in time, and improve the function modules according to the needs of the laser.


Customers are very satisfied with RFH's independent research and development of laser dedicated power supply control system, and nod frequently.


Later, I also recorded the RFH proofing workshop to experience the marking effect of RFH on 3C circuit boards, plastic packaging bags, and glasses with practical cases.


Through the brand-new mode of video tour, it has been recognized by customers and highly praised.

Looking forward to further cooperation with customers!

According to customer requirements, I recommend RFH S9 UV laser.


RFH UV laser S9 has a smaller size and more stable performance

According to market development needs, RFH's newly launched S9 series pulsed ultraviolet solid-state lasers in 2020 are smaller in size, more exquisite in design, and more stable in light output than similar products. The small and exquisite design means that users do not need to make a large optical path, which can greatly reduce costs, save space, and have good mobility. It is easy to install in the field of equipment such as flying marking. The S9 ultraviolet laser is not only compact, but also has a more stable cavity structure and stronger scalability than similar products. The same cavity can produce lasers of different powers, and the stability of different power ranges is greatly improved.

RFH UV laser S9 has stable quality and stronger competitiveness

For machine manufacturers, a good solid-state laser can effectively improve production efficiency and provide terminal equipment with stronger market competitiveness. The new product series of RFH pulsed ultraviolet solid-state laser S9 has a laser wavelength of 354.7nm and a wide range of repetition frequency (single pulse to 200kHz), which can be better absorbed by the material and is less destructive to the material. And it has superior beam quality (M2<1.2), which is strictly guaranteed in all frequency ranges; pulse width is <20ns@30k, and the heat-affected area is small during processing.

RFH UV laser S9 has full digital intelligent control function

S9 series UV lasers also have unique Q-switching control technology, full digital intelligent power control, simple operation, low cost of hands-on, and suitable for various laser application control needs; the internal cavity self-purification system makes the laser long life, stable operation, and low Maintenance costs. We fully consider the convenience of machine control in the workshop, so the laser also supports communication with the computer, and the laser can be controlled externally through RS232.
