What are the advantages of water-cooled UV laser for processing FPC flexible circuit boards?

What is a PCB flexible circuit board?

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

Processing flexible circuit boards is a technical task. Not to mention embedding a large number of precision components on thin plastic sheets, even marking a company logo or QR code on it is full of difficulties. At first, the flexible circuit board marking process used printing processes such as silk screen printing. On the one hand, the quality was low, and the clarity and wear resistance were not ideal. On the other hand, the chemical raw materials used in the process were harmful to the human body and polluted the environment. In green It is destined not to go far under the environment of manufacturing. Later, laser technology began to be applied, and the problem was solved.

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

However, is it enough to just choose a solid-state UV laser? Not really. Please read on.

As we all know, solid-state ultraviolet laser is a sophisticated and complex advanced equipment. It is composed of laser working material, pumping system, focusing system, optical resonator and other components. The quality of any component affects the performance of the laser. However, most of the solid-state ultraviolet lasers currently on the market are not integrated or integrated design, which cannot guarantee the stability of each component, and thus cannot ensure 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.

What brands of solid-state ultraviolet lasers are integrated in the market? RFH. The S9 (Shooter) series of ultraviolet pulsed solid-state lasers is one of RFH's high-end solid-state ultraviolet lasers. It has superior beam quality and spot characteristics. The ellipticity of the spot is >90%, M2<1.2, and is strictly guaranteed in all frequency ranges; pulse The width is less than 20ns@30k, and the heat-affected area is very small during processing; it has a unique Q-switching control technology, which is suitable for various laser application control requirements, and is also convenient for equipment integration; it has an inner cavity self-purification system, which makes the laser have a long life and stable operation;

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

Founded in 2007, Shenzhen RFH Laser Technology Co., Ltd. is one of the top three manufacturers of industrial-grade all-solid-state solid-state lasers in China. Headquartered in Nanshan High-tech Industrial Park, Shenzhen, with offices and Huiyang production bases in Wuhan and Suzhou.

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

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