Embodiment Construction
[0035] Ultraviolet laser roughening is the use of a specific ultraviolet laser, through a series of operations such as controlling laser parameters, using the energy of the ultraviolet laser, on the surface of the substrate to be processed, shallowly etches densely arranged fine grooves in a straight line , after two times of superimposed etching in the horizontal and vertical directions, a roughened structure with tooth-shaped bumps and ups and downs is etched on the surface of the substrate to achieve the effect of destroying the brightness and smoothness of the substrate surface. After high-temperature calcination, the surface of the roughened substrate is slightly melted, and the sharp structure at the "peaks" and "valleys" of the concave-convex undulating structure is appropriately weakened, so that the roughened structure after ultraviolet laser etching is obtained to a certain extent. Lubrication". Finally, a roughened surface with a uniform roughening effect and a Ra va...
