1. Manual and active selection
According to the characteristics of the equipment, manual, semi-active, fully active or a combination of control methods can be selected.
　　2, the selection of the method of inflating vacuum coating equipment
The inflation method can choose mass flowmeter, float flowmeter + needle valve and corresponding inflation valve, and can select multiple inflation pipelines and corresponding flow parameters.
　　3. Selection of plating method
Select plating methods and methods according to process requirements, such as resistance transpiration (tungsten wire, molybdenum boat, graphite boat) magnetron source (coaxial cylindrical magnetron source, cylindrical planar magnetron source, rectangular planar magnetron source, etc.) ) Multi-arc source based on target material and scale (Ф60, Ф80 diameter target, pneumatic and electric arc ignition, etc.), digital intelligent vacuum gauge and its high-quality measuring gauge can be selected for vacuum measurement, and other measuring instruments, such as Active pressure controller, etc. The film thickness can be measured with a square resistance measuring instrument, a transmittance meter, etc.
　　4. Working mode of vacuum coating equipment fixture
The working methods of the fixture include rotation, revolution, and revolution + rotation. The user can put forward corresponding requirements according to the size and shape of the substrate. The rolling speed range and rolling accuracy: ordinary adjustable and frequency conversion speed control, etc.
　　 5. Select the type of vacuum coating machine
According to process requirements, choose different specifications and types of coating equipment, the types include resistance evaporation, electron beam evaporation, magnetron sputtering, magnetron reactive sputtering, ion plating, hollow cathode ion plating, multi-arc ion plating, etc.
　　 6. Vacuum system
The vacuum system is composed of mechanical pumps, dispersion pumps, oil booster pumps, expansion pumps, Roots pumps, crucible molecular pumps, etc., and various pneumatic, manual, and electric valves and pipelines that match them.
　　7. The choice of grill appearance
According to the structure to be baked, the baking temperature, material and corresponding appearance measurement of the required equipment are proposed.
