What are the advantages of UV laser marking machine?

UV laser marking machine is a cold processing method. Its processing accuracy is high in visible light and infrared band lasers. Under the same conditions, the shorter the wavelength, the smaller the focused spot (the shorter the wavelength, the greater the energy of the single photon). Visible light and infrared band lasers rely on thermal effects to mark on evaporated materials, but UV light can directly break a chemical bond of the material, which is the separation of molecules from the object. The heat-affected area of processing is relatively small, and very fine materials can be marked. Because this marking method has almost no thermal effect, the index is also called laser cold processing marking.

UV laser marking machine shows high absorption rate when applied to resin and copper, and has appropriate absorption rate when processing glass. Only the expensive excimer laser (wavelength 248nm) can obtain full absorption rate when processing these main materials. This material difference makes UV laser the choice of various PCB material applications in many industrial fields, from the production of the most basic circuit boards, circuit wiring, to the production of pocket-sized embedded chips and other processes.

Compared with general laser marking machines, the ultraviolet laser marking machine has a very small spot, which makes the material's heating area smaller and less prone to heat deformation; the power is lower; the marking is more precise, and it is suitable for ultra-fine marking environments, food and medicine packaging, glass division, electronic components, metal jewelry marking, etc. It can be said that the ultraviolet laser marking machine can mark and code almost all materials, and the marking effect of the ultraviolet laser marking machine is also better than that of other laser machines. Ultraviolet laser is a kind of cold light laser, and the absorption rate of various materials for ultraviolet light is relatively high, and the thermal impact of ultraviolet laser marking is small and will not damage the material itself. Therefore, the range of ultraviolet marking that can be marked is also very wide, but its price is also relatively expensive. The practicality of the ultraviolet laser marking machine is very good.

After the successful research of the ultraviolet laser marking machine, it has prayed for a supporting construction role in the fields of energy and materials, and has a great indirect effect on the country's total economic output value, and has solved many major scientific problems, which plays a great decisive role in future development. Laser technology is an important scientific research technology in modern molecular structure, and ultraviolet laser is a powerful technical means to study various molecular structures, and has been widely used in marking applications in high-tech industries such as glass, crystals, and photovoltaics.

Laser marking technology has gradually developed significantly, especially in the past few decades. The SAN LASER series of marking machines are very professional, with good marking effects and very affordable purchase prices. If you are interested, please feel free to inquire
