With the application of UV laser getting closer to life, it has a natural charm in processing technology. With the characteristics of wave length, narrow pulse width, fast speed, easy absorption of materials and high peak value, it has become one of the mainstream industrial lasers. UV laser technology continues to mature, processing technology has been widely used and popularized. At present, the mainstream marking materials of UV lasers on the market are plastics, glass, ceramics and metals.
The thermal processing of ultraviolet laser and fiber laser is just the opposite. People usually call it "cold" processing. The workpiece is locally illuminated by the laser with high energy density to make the surface material vaporize or undergo photochemical reaction with color change, so as to achieve a permanent mark. Because UV laser marking has no consumables, and the marking effect is fine and beautiful, banning the traditional marking process has become an irreversible trend.
UV laser 3C plastic marking
3C products are emerging with the development of electronic industry in recent years. In order to meet the higher aesthetic needs of modern people, the processing technology is becoming more and more sophisticated. At the same time, in order to save production costs and a permanent sign, enterprises urgently need to find a new processing method, which has become an urgent need. The UV laser is characterized by low marking temperature and high speed, and accurate marking can be achieved through remote control of computer. Due to the unique properties of the UV laser, plastic marking will not lead to deformation of the original due to high energy, yellowing and blackening of images and texts.
Silver metal marking process
Those who know PCB well know that many parts of PCB are made of precious metal materials, including gold, silver and copper. For such small accessories, merchants often add their own unique marks on the surface in order to better distinguish them, while traditional ink-jet or sandblasting marking technologies are difficult to achieve such fine process standards. The output spot diameter of the ultraviolet laser is only 0.7mm, and the pulse width 15nm@30KHz , fine marking parameters can be realized.
Glass carving
Glass technology is often touched in daily life, and it can be used for decoration, storage, decoration, etc. Now we often see beautiful carving technology on some cups. Without any color matching, it is still beautiful as a picture, and there is no need to worry about fading and pollution sources. At the same time, the speed of UV laser engraving is more refined than manual engraving, the surface is smooth and smooth, the efficiency is higher, and the destruction in batch production is less.
UV laser equipment can be used in many fields of flexible board production, including FPC profile cutting, contour cutting, drilling, covering film opening window, soft and hard bonding board uncovering and trimming, mobile phone shell cutting, PCB profile cutting and other processing fields. The laser marking handwriting is clear and bright, and can be marked with black and white handwriting.
At present, the UV laser technology is relatively mature in 3-10W and widely used in various industrial "micro processing" fields, which can be directly used for wafer cutting, ceramic cutting, film etching, laser marking, etc. In the context of the "Made in China 2025" strategy, the traditional industrial manufacturing industry is facing a deep transformation. One of the directions is to turn to high-end precision processing with higher added value and higher technical barriers while improving efficiency. The development of ultraviolet laser technology is fully in line with this trend.
Riselaser is an integrated manufacturer of laser accessories engaged in the R&D, production and sales of solid state lasers. After years of precipitation, the power of ultraviolet lasers has increased from 1W to 5W to 10W, 15W to 20W, which can meet the needs of different processing technologies in the market. The large increase of power makes the machining performance double. And it can achieve ultra fine processing effect, such as no edge burning, no carbonization, small thermal effect, and finally meet the requirements of modern technology.
