S9 UV laser marking white effect on the surface of switching power adapter

Every Huawei mobile phone will be equipped with a switching power adapter, and there will be indelible marks such as LOGO, QR code, model and production location on one end of the plug.

As we all know, the traditional marking method is to use ink to print, the ink is placed in the inkjet printer, and the ink and thinner are consumed for processing, which not only pollutes the environment, but also easily causes the marking to fade and fall, which is used by criminals to produce fake and shoddy products . The Huawei switching power adapter uses laser energy to break the bonds between atoms or molecules, making them into small molecules that vaporize and evaporate, so as to get the text or pattern that you want to mark, that is, use laser to make black on white plastic. The content or pattern is fine, does not fade, and does not deform.

RFH has 13 years of ingenuity and has focused on global industrial-grade solid-state laser manufacturing. RFH covers a range of lasers from green to deep ultraviolet. Its products have been used in 3C Electronics with its fast speed, high precision, high stability, and small and exquisite characteristics. Establish an excellent brand image in the field of marking.

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

Ultraviolet lasers usually output wavelengths below 0.4μm, which is the main advantage of processing polymer materials. Unlike infrared processing, ultraviolet micro-processing is not essentially a heat treatment, and most materials absorb ultraviolet light more easily than infrared light. The short wavelength of ultraviolet itself has advantages for the mechanical micro-processing of metals and polymers. It can be focused to a point on the order of sub-micrometers, so it is widely used in the processing of fine parts.

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 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.

After 13 years of development and precipitation, RFH laser currently has a senior laser research and development team composed of professors, experts, and doctors at home and abroad. Each laser product produced can maintain a consistent and stable quality under extreme industrial and scientific research conditions. The beam quality, high efficiency power consumption characteristics, superior cost performance and high reliability have won high recognition and good reputation from users in all walks of life at home and abroad.
