    Precautions for starting the vacuum unit of the vacuum coating machine

    Precautions for starting the vacuum unit of the vacuum coating machine 1. Check and confirm that the vacuum pipeline and flange from the pumped container to the air inlet of the vacuum pump are in good condition, the valves are open, and the valves on the pumped container should be closed. 2. Confirm that there is no liquid accumulation in the vacuum buffer tank before the pump, and the nitrogen pressure valve, emptying valve and bottom valve are all closed. 3. Check that the lubricating oil ... read more

    Talking about the skills of vacuum leak detection?

    Talking about the skills of vacuum leak detection? Finding leaks quickly requires considerable experience and skill. Although there is no certain operating rules for vacuum leak detection, it is generally better to operate according to the following procedures and methods. 1) For the vacuum container or device in the process of manufacturing, it is best to use the bubble leak detection method. Bubble leak detection is to fill the test piece with a certain pressure of leak-indicating gas and t... read more

    Analysis of common evaporation coating technology

    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

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

    What is the difference between evaporative coating and magnetron sputtering?

    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
