1. Resistance evaporation plating: The resistance evaporation source is used to evaporate low melting point materials, such as gold, silver, zinc sulfide, magnesium fluoride, chromium trioxide, etc. Resistance evaporation sources are generally made of tungsten, molybdenum and tantalum. 2. Electron beam evaporation plating: After the film material is vaporized and evaporated by electron beam heating, it is condensed on the surface of the substrate to form a film, which is an important heating me... read more
Evaporation coating is to heat the target material so that the surface components are evaporated in the form of atomic groups or ions, and settle on the surface of the substrate to form a thin film through the film formation process (scattered point - island structure - vagus structure - layered growth). The uniformity of the components of the evaporation coating is not very easy to guarantee, and the specific control factors are the same as above, but because of the limited principle, the unif... read more
The problem of holes in the film when the vacuum coating machine is aluminized can generally be solved by the following methods: ①The aluminum material in the evaporation boat is too full. Solution: reduce the speed of aluminum feeding; increase the current of the evaporation boat. ② There is a short circuit between the evaporation boats in the vacuum chamber. Solution: Eliminate short circuits. ③ Impurities splash in the vacuum chamber. ①The tension of the substrate is too high. Solution: A... read more
In our daily life, we come into contact with a lot of products coated by vacuum coating machines. For example, we now have a mobile phone, mobile phone case, mobile phone screen, mobile phone camera, etc., all of which are coated with a layer of the optical vacuum coating machine. Sexual or color film. The packaging of our women's daily skin care products, as well as the sparkling gold and silver threads on our clothes, have been coated with a layer of the film by a vacuum coating machine. The a... read more
DC Magnetron Sputtering, RF Magnetron Sputtering, Pulsed Magnetron Sputtering and Medium Fre2quency Magnetron Sputtering Reactive sputtering is to introduce a certain proportion of reactive gas into the inert gas atmosphere in the sputtering system. Usually, the main reactive gases are oxygen and nitrogen. The DC sputtering method is used in sputtering and reactive sputtering coating where the sputtered material is a conductive material, and the process equipment is simple and has a high sputt... read more
