    Ten Problems in PVD Coating Processing (Part 1)

    1. What is PVD coating technology? Answer: PVD is the abbreviation of Physical Vapor Deposition in English, and it means "physical vapor deposition" in Chinese. It refers to the thin film preparation technology that uses physical methods to deposit materials on the workpiece to be plated under vacuum conditions. 2. What are the classifications of PVD technology? Are there any PVD coating machines? Answer: PVD (physical vapor deposition) technology is mainly divided into three categories, vacu... read more

    How to use vacuum coating equipment correctly?

           In the case of normal operation of the machine tool, to start the machine, you must first open the water pipe, and you should always pay attention to the working water pressure.        At the same time, ion bombardment and evaporation, special attention should be paid to the high-voltage wire connector, which should not be touched to prevent electric shock. Electron gun in coating, peripheral bell to aluminum. It is best to observe the window glass with lead glass, and you should wear gl... read more

  • What is the difference between evaporative coating and sputtering coating?

    What is the difference between evaporative coating and sputtering coating?

    Vacuum evaporation film is to heat the material to be evaporated to a certain temperature by resistance heating or electron beam and laser bombardment in an environment with a vacuum degree of not less than 10-2Pa, so that the thermal vibration energy of molecules or atoms in the material exceeds the surface. Therefore, a large number of molecules or atoms are evaporated or sublimated, and deposited directly on the substrate to form a thin film. Ion sputtering coating is to use the high motion o... read more
