Application of UV laser cutting machine in high-end industry

With the gradual maturity and stability of ultraviolet lasers, the laser processing industry has shifted from infrared lasers to ultraviolet lasers. At the same time, the application of ultraviolet lasers is becoming more and more popular, and laser applications are moving towards a broader field.

       Ultraviolet laser wafer cutting, the surface of the sapphire substrate is hard, and the general cutter wheel is difficult to cut, and the wear is large, the yield is low, and the cutting path is larger than 30 μm, which not only reduces the use area, but also reduces the output of the product. Driven by the blue and white LED industry, the demand for sapphire substrate wafer cutting has increased greatly, and higher requirements have been put forward for improving productivity and finished product qualification rate.

       Ultraviolet laser ceramic cutting. In the last century, the application of electronic ceramics has gradually matured, with a wider range of applications, such as heat dissipation substrates, piezoelectric materials, resistors, semiconductor applications, biological applications, etc. In addition to traditional ceramic processing technology, ceramic processing also depends on the types of applications. The increase in laser processing technology has entered the field of laser processing. According to the types of ceramic materials, it can be divided into functional ceramics, structural ceramics and bio-ceramics. Lasers that can be used to process ceramics include CO2 lasers, YAG lasers, green lasers, etc. However, with the gradual miniaturization of components, ultraviolet laser processing has become a necessary processing method, which can process many types of ceramics.

       Ultraviolet laser glass cutting, and the application of ultraviolet laser, driven by the rise of smart phones, gradually has room for development. In the past, because mobile phones did not have many functions and the cost of laser processing was high, laser processing did not occupy much position in the mobile phone market. However, smart phones now have many functions and are highly integrated. It is necessary to integrate data in a limited space. Ten kinds of sensors and hundreds of functional devices, and the high cost of components, so the accuracy, yield, and processing requirements have greatly increased, and ultraviolet lasers have developed a variety of applications in the mobile phone industry.

       Ultraviolet laser ITO dry etching, the biggest feature of smart phones is the touch screen function. Capacitive touch screens can achieve multi-touch. Corresponding to resistive touch screens, it has longer life and faster response. Therefore, capacitive touch screens have become smart The mainstream of mobile phone selection.

       Ultraviolet laser circuit board cutting, circuit board cutting with laser was first used for flexible circuit board cutting. Because there are many kinds of circuit boards, early processing uses mold forming, but the production cost of molds is high and the production cycle is long, so ultraviolet lasers are used. Processing can eliminate the cost and cycle of mold making, and greatly increase the time for sample making.
