Laser Applications in LED Industry
Laser cutting machine has been widely used in semiconductor, LED and photovoltaic, solar energy and many other fields.
When the sapphire as the substrate material, is widely used in LED chip production, the traditional cutting tool has been unable to meet the cutting requirements, manufacturers have been using 355nm and 266nm short wavelength nanosecond green laser pointers scribing, processing of sapphire wafer, the way to solve the difficulty of sapphire cutting and LED industry requirements for small and narrow cutting chip for, on sapphire substrate LED scale production, and may provide a guarantee of high quality cutting.
With the development of blue green LED chip technology and the expansion of scale, the demand for laser cutting equipment is higher and higher, which has forced the laser equipment supplier to upgrade the equipment. At the same time due to a decrease in the development of laser technology and the price of domestic laser dicing equipment also began to enter the market, a new generation of UV laser dicing equipment occurs, its production capacity has been increased to 3-5 times the generation of dicing machine, up to 15 pieces per hour.
Cutting effect: wide opening, high cutting efficiency, short laser pulse, obvious gasification, more suitable for side wall corrosion process. With the rapid development of red laser pointer applications, the upstream optical component enterprises benefit from the development of the industry, showing overall growth. As the basic components, it has played a catalytic role in the development of laser industry.
Optical components in the field of laser are actually relatively special optical components, and compared with other fields, we can say that the requirements are the highest. At present, the main products are as follows: first, the optical components of semiconductor laser. The two is laser cutting head with focusing lens and collimating lens. Three, laser materials, optical shaping, such as the current market is very popular OLED screen, large cylindrical mirror is widely used in OLED display panel, LTPS laser annealing system. The four is the laser field mirror, which is usually used in laser cutting heads. The focusing direction of more than four products is the main optical record.
Laser market is always in development, so the opportunity must exist, such as industrial 4.0, AI, automation and other high-tech or ideas, will give it to provide strong support. Speaking of challenges, laser companies to maintain product reliability, consistency, while, as always, for mass production. This is the biggest challenge in the blue laser pointer optics industry. The development of fiber laser power for optical components of the performance requirements are getting higher and higher, such as roughness, high finish, coating and substrate.
Fiber laser resonator is a solid-state laser, equipped with a permanent seal connected to the continuous fiber to prevent dust and dirt generation, and does not contain moving parts or free space lenses, resonators without any adjustments, no supplies, no maintenance The These features help to ensure the performance of the laser, so that it maintains stability and consistency during years of operation. In the absence of consumable parts, the output power is not attenuated, the beam quality of the laser output remains the same, and no longer requires the technician to make regular adjustments to maintain the normal operation of the laser processing system.
Fiber laser technology enables very high power in very small packages. This is very attractive for most companies because the reduced footprint of the high power laser results in a reduction in the overall space required for the integrated laser process. Global companies seem to have been looking for ways to fill more stuff in less space, and low space for fiber lasers can do that.
