Taiwan Industrial Technology Institute of Taiwan launched the 2014 Taiwan Laser Industry International Exhibition, which was launched on the 22nd. It was the first to publish the first set of self-developed Pinaisecond dual-pulse fiber laser source in Taiwan. It has been tested in the LED packaging factory in Taiwan. Enhance LED production efficiency and quality in Taiwan. At the same time, it also published semiconductor thermal ceramic substrate drilling, laser printing and color laser engraving. Xu Shaozhong, CEO of the South Branch of the Taiwan Industrial Research Institute, said that ceramic materials have the advantages of low thermal expansion coefficient, high humidity resistance, insulation, high thermal conductivity, high hardness and wear resistance. In recent years, they have been widely used in light-emitting diode (LED) light sources. Module and integrated circuit board (IC) high power cooling module. The existing precision ceramics are non-metallic hard and brittle materials, using traditional mechanical drilling, which has the difficulty of large holes and easy to be broken. The current industry adopts ultraviolet nanosecond laser, but it has the problem of high price and slow processing speed. Xu Shaozhong pointed out that the optical architecture patent can be used for continuous processing of laser pulses and picoseconds (10 minus 12ths of a second) pulses in nanoseconds (10 negative 9ths of a second) and applied to the micro-drilling process of LED ceramic heat sinks. The aperture size is less than 100 micrometers, the processing speed is 4 times faster than the current ultraviolet nanosecond laser, and there is no cleavage phenomenon, and the speed is fast, the hole is small, the quality is excellent, and the cost is only ultraviolet light nanosecond laser 2/3 It has been tested in the LED packaging factory in Taiwan and will help improve LED production efficiency and quality. Xu Shaozhong said that laser source related technology can also be applied to color laser engraving, with nanometer laser and chrome oxide on the surface of stainless steel. Through different laser power and time parameters, dozens of colorful colors can be presented. The color and color are full and long-lasting, which has led to a company to invest in laser engraving and creation. In addition, the related technology is also applied to laser printing, the speed is 50 to 100 faster than the international manufacturers, the technology has been transferred to the company, and successfully imported into the memory module production line printing.
