Everyone is familiar with the UV laser printer. Its working principle is that UV is a cold process with little thermal influence. By changing the molecular results on the surface of the object, a permanent mark is formed. The power pulse width output is stable, and the reaction of ultraviolet laser processing is realized by laser chemical ablation, relying on the laser energy to break the bonding between atoms and molecules, making them vaporize and evaporate into small molecules, thus forming the various identification information we need. Therefore, it is mainly used for ultra-fine marking and engraving, and is especially suitable for applications such as food, pharmaceutical packaging material marking, micro-hole drilling, high-speed division of glass materials, and complex pattern cutting of silicon wafers.
