According to the China Electronics Industry Association statistics, China is the world's television sets, tape recorders, VCD disc players, telephones, electronic watches, calculators, and refrigerators, air conditioners and other production superpower, is a program-controlled switches, PC machine , mobile phones, soft and hard drives, monitors, computer boards, mouse, and other products of the major producing countries. Broad range of electronic products and manufacturing standard easy-to-unity, which is laser marking provides a huge space.

     Laser Marking Principle:

    "Thermal processing" - has a high energy density laser beam (which is the focus of energy flow), irradiation in the processing surface, the surface absorb the laser energy to generate heat in the irradiated region to stimulate the process, so that the surface (or coating) temperature rise, resulting in abnormal, melting, ablation, evaporation and other phenomena.

"Cold" - high load energy (UV) photons, can interrupt the materials (especially organic material) or chemical bonds within the surrounding medium, to the non-thermal process of the material damage occurred. This cold laser tag in the processing of special significance, because it is not thermal ablation, but do not have a "thermal injury" side effects, cold peel break chemical bonds, and thus be processed in the surface layer and not near the area produce heat or hot deformation and so on. For example, the electronics industry in the use of excimer laser deposition of chemicals on the substrate film, the semiconductor substrate out of the narrow slot.
         
Laser marking features: wide range of applications, a variety of materials (metal, glass, ceramics, plastics, leather, etc.) can be marked with a permanent high quality mark. No force on the surface, does not produce mechanical deformation of the material surface is not corrosive. Can be used for integrated circuits, resistors, capacitors, crystals, diodes, transistors and other components of the mark.
