The various types of vacuum coating and working methods

   

Now according to the technical requirements for vacuum coating equipment select different standards and types of coating equipment, its type resistance evaporation, electron beam evaporation, magnetron sputtering, magnetron sputtering, ion plating, hollow cathode arc ion plating, ion plating, etc. Fixture working method of the rotation, light coating machine revolution and the revolution and rotation combination method, users can according to the substrate size and shape, put forward the corresponding requirements, changes the speed of the scale and precision: general adjustable and frequency control of motor speed, etc. By the mechanical pump and the vacuum system, distributed pump, oil pump, enlargement pump, roots pump and molecular pump crucible round and match them all kinds of pneumatic, manual, electric valves, pipes, etc. According to technical requirements selected plating method and the method, to choose a suitable coating machine, and coating mechanical type so much, and the internal gear is also there are so many kinds.
If it is not the right choice, then it will be difficult to play for the biggest effect of vacuum coating machine, and the above said tial mainly suitable for use to metal materials and surface treatment in crystalline materials. For resistance evaporation, electron beam evaporation is suitable for use to the city a kind of common items of surface treatment, and said to the fixture, light coating machine is typical of the kind.
