Uv laser marking machine, in the process of reaction mechanism is achieved through photochemical ablation, that is, rely on laser energy to break the bonds between atoms or molecules, make it into small molecules gasification, evaporation.  The focusing spot is very small, and the processing heat affected area is very small, so it can be ultra-fine marking, special material marking.

Now, with the rapid development of laser equipment, uv laser marking machine power improvement, UV laser marking machine has been used in ultra-fine processing market, iPhone, cosmetics, drugs, food and other polymer materials packaging bottle surface marking;  Flexible PCB board marking and scribing;  Silicon wafer microhole, blind hole processing;  LCD liquid crystal glass, glassware surface, metal surface coating, plastic keys, electronic components, gifts, communication equipment, building materials and other fields.

YOUNGPOOL UV laser marking machine is mainly used for metal shield cover on PCB board.  The principle is that the laser light of ultraviolet laser marking machine evaporates the surface layer of the target material and exposes the deep layer of the material, so as to "carve" the required pattern text. In simple terms, it is to use the laser beam to print long-term marks on the surface of various substances.
