What materials can UV Laser Marking & Engraving source mark?

As the application of ultraviolet lasers is getting closer to life, it has a natural charm in processing technology. With the characteristics of short wavelength, narrow pulse width, fast speed, easy absorption of materials, and high peak value, it has become one of the mainstream industrial lasers. With the continuous maturity of UV laser technology, the 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.

Ultraviolet laser and fiber laser thermal processing are just the opposite. People usually call it "cold" processing. The workpiece is partially irradiated by a high-energy-density laser to vaporize the surface material or undergo a photochemical reaction of color change, so as to achieve a permanent sex sign. Because UV laser marking has no consumables, and the marking effect is fine and beautiful, it has become an irreversible trend to ban the traditional marking process.

3C products are newly emerging with the development of the electronics industry in recent years, and 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 mark, enterprises urgently need to find a new processing method, which has become an urgent need at present. Ultraviolet laser marking temperature is low, speed is fast, and accurate marking can be achieved through computer remote control. Due to the unique properties of UV lasers, plastic marking will not cause deformation of the original due to high energy, yellowing and blackening of images and texts.

Silver metal marking process, friends who know circuit boards know that many parts of PCB are composed of precious metal materials, including gold, silver and copper. For small accessories like this, merchants often add their own unique logos on the surface in order to better distinguish them, and it is difficult to achieve such fine craftsmanship standards with traditional inkjet or sandblasting marking technologies. The output spot diameter of the ultraviolet laser is only 0.7mm, and the pulse width is 15nm@30KHz, which can realize fine marking parameters

Glass craftsmanship is often contacted in daily life. It can be used for decoration, storage, decoration, etc. Now we often see beautiful carving craftsmanship on some cups. source of pollution. At the same time, the speed of UV laser engraving is more refined than manual engraving, the surface is flat and smooth, the efficiency is higher, and the destructiveness in mass production is less.

Ultraviolet laser equipment can be used in many fields in the production of flexible boards, including FPC shape cutting, contour cutting, drilling, cover film window opening, flex-rigid board uncovering and trimming, mobile phone case cutting, PCB shape cutting And so on the processing field. The handwriting of laser marking is clear and bright, and black and white handwriting can be marked.
