315, 310, 210 Stamped Tungsten Boats For Vacuum Evaporation Sputtering Coating Heat Treatment
1. Information Of 315,310,210 Stamped Tungsten Boats:
Vacuum coating tungsten boat is a kind of laboratory equipment used in vacuum evaporation, sputter coating and other fields, and is mainly used as a container for carrying and protecting coating materials. Compared with ordinary stamped tungsten boats, vacuum coating tungsten boats need to have a higher vacuum degree and better material purity to ensure the quality and stability of the coating.
Vacuum coating tungsten boats are generally made of high-purity tungsten materials. Through precision machining and surface treatment, the surface is smooth and free of impurities, and can withstand harsh working environments such as high temperature and high vacuum. In the experiment, the material to be coated is placed in a vacuum coating tungsten boat, and evaporated or sputtered by heating, electron beam bombardment, etc., so as to form a uniform film on the surface of the substrate.
