As a non-contact processing method, laser has been applied in more and more fields.

Although the current traditional processing methods are very mature, there are still many problems such as surface scratches, low substrate utilization, large processing losses, and complicated processes. In addition, laser cutting can realize non-contact processing without damaging the film surface, high precision, fast speed, narrow cutting slit, small heat-affected zone, smooth cutting surface without burrs, flexible processing, and can process any shape. There is no need to paint the protective coating surface, the cutting speed is fast, and the utilization rate of the substrate is improved.
