How to choose PVD vacuum coating machine（PVD vacuum coating equipment,Vacuum aluminum plating machine)
The advantages of vacuum coating machines in product surface treatment are still obvious. Compared with other surface treatment equipment, the coating machine itself needs to be processed in a vacuum environment. This coating method "shields" some external factors, which is the advantage of other machines.
The key points of vacuum coating machine procurement are as follows:
1. The furnace body can adopt a double-layer water-cooled structure of stainless steel, carbon steel or a combination thereof.
2. According to process requirements, choose different specifications and models of coating equipment, including resistance evaporation, electron beam evaporation, magnetron sputtering, magnetron reactive sputtering, ion plating, hollow cathode ion plating, multi-arc ion plating, etc.
3. The working mode of the fixture includes rotation, rotation and rotation + rotation. Users can put forward corresponding requirements according to the size and shape of the substrate. Speed control range and speed control precision: generally adjustable, frequency conversion speed control, etc.
4. The vacuum system is composed of mechanical pump, diffusion pump, booster oil pump, expansion pump, Roots pump, crucible wheel molecular pump and other supporting pneumatic, manual and electric valves and pipelines.
5. According to process requirements, choose electroplating method and form, such as resistance evaporation (tungsten wire, molybdenum boat, graphite boat) magnetron source (coaxial cylindrical magnetron source, cylindrical magnetron source, rectangular magnetron source, etc.), Multi-arc sources can be selected for measuring instruments such as vacuum measuring instruments and automatic pressure controllers, and the target material and size (diameter? 0? diameter is 0? The thickness of the film can be measured with a block resistance meter and a transmittance meter.
6. The filling method can choose mass flowmeter, rotameter + needle valve and corresponding filling valve, and multiple filling pipelines and corresponding flow parameters can be selected.
7. According to the baking structure, the baking temperature, materials and corresponding equipment are proposed.
8. According to the characteristics of the equipment, you can choose manual, semi-automatic, fully automatic or their combination.
9. Complete alarm system for vacuum coating machine, sound and light alarms for abnormal conditions such as phase loss, water shortage, air pressure, power load, overvoltage, and overcurrent in the vacuum chamber body, diffusion pump, etc.
