【summary】

With the gradual maturity and improvement of the 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 has become more and more popular, and the application of lasers has become more and more extensive.

With the gradual maturity and improvement of 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 the application of lasers is becoming more and more extensive.

Ultraviolet laser wafer cutting, the surface of sapphire substrates is hard, and it is difficult to cut with general cutter wheels, and the wear is large, the yield is low, and the cutting channel is greater than 30渭m, which not only reduces the use area, but also reduces the product output. With the promotion of the blue and white light LED industry, the demand for sapphire substrate wafer cutting has increased significantly, and higher requirements have been put forward for improving productivity and finished product qualification rate.

UV laser cutting, the application of electronic ceramics gradually matured in the last century, and its application scope became wider and wider, such as heat dissipation substrates, piezoelectric materials, resistors, semiconductors, biology, etc. In addition to traditional ceramic production processes, ceramic processing has also entered the laser processing industry with the increase in application types. According to the type of materials, it can be divided into functional ceramics, structural ceramics and bioceramics. The lasers that can be used to process ceramics include CO2 lasers, YAG lasers, green lasers, etc., but with the gradual miniaturization of components, UV lasers have become a necessary processing method and can be used to process a variety of ceramics.

Ultraviolet laser glass cutting, the application of ultraviolet laser has gradually gained room for development driven by the rise of smart phones. In the past, due to the limited functions of mobile phones and the high cost of laser processing, laser processing did not play a big role in the mobile phone market. However, now smart phones have many functions and high integration. Dozens of sensors and hundreds of functional devices need to be integrated in a limited space, and the component cost is high, so the requirements for accuracy, yield and processing have been greatly improved. UV laser has developed a variety of applications in the mobile phone industry.

UV laser ITO dry etching, the biggest feature of smart phones is the touch screen function. Capacitive touch screens can achieve multi-point touch, which is longer in life and faster in response than resistive touch screens, so capacitive touch screens have become the mainstream choice for smart phones.

Ultraviolet laser circuit board cutting, circuit boards are cut by laser, which was first used for flexible circuit board cutting. Due to the wide variety of circuit boards, early processing used mold forming, but the mold manufacturing cost was high and the production cycle was long. Therefore, ultraviolet laser processing can avoid mold manufacturing costs and production cycles, greatly improving sample manufacturing time.
