RFH solid-state UV lasers are widely used in PCB FPC QR code marking

PCB flexible circuit board QR code marking has little thermal effect on RFH355nm ultraviolet laser, and the processing effect is fine. Tsk praise

The day before yesterday, when I visited a PCB flexible circuit board QR code marking user, the customer had little thermal effect on the RFH355nm ultraviolet laser and the processing effect was fine. He praised it.

What is a PCB flexible circuit board?

A flexible circuit board is a kind of PCB board, but unlike other PCB boards, it is a flexible circuit that can be bent. The flexible circuit board that can be bent at will break through the traditional interconnection technology and increase more processing possibilities.

Processing flexible circuit boards is a technical task. Not to mention stacking a large number of precision components on thin and light plastic sheets, even marking a corporate logo or QR code on it is also very difficult. In the beginning, the flexible circuit board marking process used silk screen and other printing processes. On the one hand, the quality was low, the clarity and wear resistance were not ideal, and the chemical raw materials used in the process were harmful to the human body and polluted the environment. The manufacturing environment is destined to not go far. Later, laser technology began to be applied to solve the problem.

Compared with the traditional printing process, the emerging laser marking process has obvious advantages: high marking accuracy, fast speed, and simpler operation. It only needs to preset a computer program to mass produce circuit boards that meet the requirements. Currently, UV laser marking technology and CO2 laser marking technology are mainly used to mark flexible circuit boards. Compared with the CO2 laser with the wavelength of 10640nm, the ultraviolet laser with the wavelength of 355nm has less thermal influence and better processing effect, and then it becomes the standard configuration of flexible circuit board marking.

But, can I just choose a solid-state UV laser? Not really. Please read on.

As we all know, the solid-state ultraviolet laser is a sophisticated and complex advanced equipment. It is composed of laser working material, pumping system, condensing system, optical resonant cavity and other components. The quality of any component affects the performance of the laser. However, most of the solid-state UV lasers currently on the market are not integrated or integrated design, which cannot guarantee the stability of each component, and thus cannot guarantee that the beam quality is strictly controlled within a certain frequency range, so that it cannot be guaranteed. The yield rate of flexible circuit boards.

In the market, which brands of solid-state UV lasers are integrated? RFH. Expert Ⅱ (shooter) series of UV pulsed solid-state lasers is one of RFH high-end solid-state UV lasers. It has superior beam quality and spot characteristics, with spot ellipticity >90% and M2<1.2, which are strictly guaranteed in all frequency ranges; Pulse width <20ns@30k, the heat-affected area is small during processing; it has a unique Q-switching control technology, which is suitable for various laser application control needs, and is also convenient for equipment integration; has an internal cavity self-purification system, which makes the laser long life and stable operation ；

The operation of these technologies is very simple, don't worry, because it adopts all-digital intelligent power control technology, supports communication with the computer, and can control the laser externally through RS232.

Shenzhen RFH Laser Technology Co., Ltd. was founded in 2007 and is the top three industrial-grade solid-state solid-state laser manufacturer in China. Headquartered in Shenzhen Nanshan High-tech Industrial Park, and established offices in Wuhan and Suzhou and Huiyang production base.

After 12 years of development, RFH Laser currently has a top-level laser R&D team composed of Tsinghua professors and Ph.Ds. It has set up application process R&D department, laser R&D department, electrical R&D department, 10 national patent certificates, and 14 computer software copyright certificates. , Won the "National High-tech Enterprise", "Shenzhen High-tech Enterprise", "Software Enterprise Certification Certificate" and other certificates, and was appointed as the governing unit by the Guangdong 3D Printing Industry Innovation Alliance and the Guangdong Laser Industry Association.

First-class technology, first-class quality, first-class service, RFH ultraviolet laser, you deserve it!
