With the continuous economic development, vacuum coating technology has long been widely used in various energy development, such as electronics, optics, surface science, scientific research and other fields. If the purpose of vacuum coating is to change the physical and chemical properties of the material surface, then this is an important part of the vacuum surface treatment technology; today, the Guangdong vacuum coating machine manufacturer introduces in detail:

In terms of optics, after coating one or several layers of different material films on a piece of optical glass or quartz surface, it can become highly reflective or non-reflective (that is, antireflection coating) or reflect or reflect any desired proportions. The transmissive material can also be a color filter that absorbs a certain wavelength and transmits another wavelength.

In terms of components, evaporating nickel and chromium, chromium or metal ceramics in a vacuum can make resistors, evaporating aluminum, silicon monoxide, titanium dioxide, etc. on a plastic coating machine to make capacitors, and evaporating selenium to obtain toner cartridges for electrostatic copiers and evaporating barium titanate. It is possible to manufacture magnetostrictive sound elements and so on. The vacuum evaporation coating machine can also be used to manufacture superconducting films and bead coatings for inertial confinement reactions. In addition, it can also use evaporation coating machine to evaporate decorative film on jewelry, watch shell surface, textile metal pattern, gold wire and silver thread, and use sputter control sputter coating machine to make super hard film on tools, molds, etc.

Vacuum coating occupies an extremely important position in electronics. Inherited circuits of all sizes. Including memory, arithmetic unit, telling logic components, etc., conductive film, insulating film and protective film must be used. A chromium film is used as a mask for preparing the circuit.
