Key points of production and quality control of coating process
The working principle of vacuum coating is that the film evaporates at high temperature and crystallizes on the surface of the workpiece. Because the air will produce resistance to the evaporation of the membrane molecules caused by collision so that the crystal becomes rough and matt,
Coating power supply in vacuum coating (magnetron sputtering), why is pulse bias power supply better than DC power supply?
Vacuum coating A technique for producing thin film materials by physical means. In the vacuum chamber atoms of the material are isolated from the heating source and hit onto the surface of the plated object.
