Laser laser engraving QR code on PCB circuit board, small cutting line width, no carbonization

Nowadays, QR codes have become an indispensable part of our daily necessities. We can use QR codes to pay, search, register and even store personal information. Engraving a two-dimensional code on a PCB circuit board can facilitate users to query and search for information, and to a large extent, it is convenient for consumers to use and find. But how to engrave a QR code on a limited or even narrow position on a PCB circuit board? The UV laser developed and produced by RFH can clearly mark and engrave the required two-dimensional code and text in narrow places without affecting the use of PCB circuit boards. The two-dimensional code marked with this laser has clear lines and shapes, and will not fade in the long-term heat and use, can ensure that the required information is displayed at any time, and the use time can be greatly extended.

Ultraviolet laser is a cold light source with small light spot, low thermal influence, small cutting line width, no carbonization, and no burrs. It is a wise choice for PCB circuit board engraving two-dimensional code.

The customer of the PCB circuit board laser marking machine from Wuhan has just placed an order to purchase the RFH 15W high-power ultraviolet laser for engraving PCB QR codes.

RFH Seiko 13 years, the 15W high-power ultraviolet laser specially developed and produced by foreign professors and doctoral-level teams has the characteristics of low thermal influence, ±0.002mm high precision, and high power stability. It is used for cutting and perforating on PCB circuit boards. , During the engraving process, it can effectively avoid the burr, and the cut is neat and smooth, without burrs, and no dust particles, so it is widely used in the PCB and FPC circuit board processing industries.

10W-15W high power UV laser is specially designed for FPC/PCB cutting

The Expert III 355 series UV diode-pumped pulsed solid-state laser developed and produced by RFH has a power range of 10W-15W. It adopts a unique laser cavity design, acousto-optic Q-switching technology, and high-precision cooling system, small size and high integration. It has a short pulse width (<20ns@40k), superior beam quality (M²<1.2) and perfect spot characteristics (spot ellipticity>90%).

±0.002mm high precision, production in dust-free workshop throughout the process

From procurement-pre-production quality inspection control-rigorous assembly process-finished product testing-warehousing quality inspection-pre-delivery inspection-after-sales service, each level is checked to ensure stable quality and consistency of equipment parameters with actual operating parameters. The clean production environment ensures that all electronic components are produced dust-free and free from pollution. This is the reason why the service life of RFH brand lasers is better than that of peers

Professor and doctoral-level team, independently research and develop the laser dedicated power control system

There is a one-to-one correspondence between the power supply and the laser. The stability of the power supply 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.

Power supply + laser head + cooling system, complete system sales From the user's point of view, RFH has launched a complete laser system sales program to ensure the stability of the entire laser system and maximize its performance

Each laser developed and produced by RFH adopts all-digital intelligent power control technology, supports communication with a computer, can remotely monitor the laser, and has an integrated compact design for easy equipment integration. Able to maintain consistent stable quality, constant beam quality, high-efficiency power consumption under extreme conditions of industry and scientific research, with superior cost performance and high reliability, it has won high recognition and good reputation from users in all walks of life at home and abroad.
