Micro Chiller for UV Marking Machine

With the continuous development of laser technology, the application fields of laser marking are becoming more and more extensive. Laser marking machines are generally classified into: fiber laser marking machines, CO2 laser marking machines and UV laser marking machines. Today we will briefly talk about common UV laser marking.

Ultraviolet laser marking is different from infrared. The ultraviolet laser marking machine uses third-order intracavity frequency doubling technology and is developed with a 355nm ultraviolet laser. Compared with infrared lasers, the 355 ultraviolet laser has a smaller focus spot and can The mechanical deformation of the material is reduced, and the processing heat is less affected. Therefore, UV laser marking is not heat treatment in essence, but a kind of cold processing.

With its unique low-power laser beam, the UV laser marking machine has a very wide range of applications. The common ones are laser wire drawing of laptop shell, transparent marking of keyboard and marking of plastic accessories, marking of mobile phone keys, etc. In addition to these common electronic manufacturing industries, UV laser marking machines are also widely used in some high-end industries. For example, the UV laser machine can be used in the deep engraving industry, on the circuit board, in the drilling and so on. An application of laser marking machines due to the small beam size and low stress properties of UV lasers is the drilling of holes, including through-holes, micro-vias and blind buried vias. UV laser systems drill holes by cutting a focused vertical beam straight through the substrate. Depending on the material used, holes as small as 10µm can be drilled, and UV lasers are particularly useful for multilayer drilling.

With the continuous expansion of the application of UV marking machines, in the future advanced intelligent manufacturing industry, with its many advantages, it is believed that the application will become more and more extensive. At the scene of the ultraviolet laser marking machine, you often see the existence of the laser chiller to precisely control and cool down the temperature. And we are a manufacturer that provides temperature control for this field.
