pvd coating machine film control system, look at the name may be able to guess, it should be the coating machine in the coating process, to monitor and control the coating process of the coating system, so that coating engineers can ensure that the entire coating process can be successfully completed.

pvd coating machine film monitoring is currently applied in more ways, mainly: visual monitoring method, fixed (extreme value) value monitoring, crystal oscillation monitoring, time monitoring and so on. I mainly introduce visual monitoring, constant (extreme value) monitoring and crystal oscillation monitoring three kinds.
Visual monitoring is also called direct monitoring, that is, the use of eye monitoring, because the film in the process of growth, due to interference phenomenon will have color changes, we are based on color changes to control the film thickness, this way has a certain error, so it is not very accurate, need to rely on experience.
The electrical control part mainly uses PLC automatic control, that is, first enter the pre-designed program in the PLC, the main circuit of the processor is connected with the empty driving system on the operation panel, when the switch on the operation panel is pressed, the information is transmitted to the central processor, and then the central control system analyzes and issues instructions by the branch to execute and complete the action.
Coating machine is a multi-disciplinary equipment, IT integrates the most advanced electromechanical technology in today's industry, control technology, electrical automation, IT technology, refrigeration technology, Microcircuit integrated system, high voltage control system, mechanical technology, processing technology, photoelectric technology, optical technology, pneumatic control technology, photoelectric sensing technology, communication technology, vacuum technology, thin film optics and coating technology, etc.
It can be said that the coating machine is an emerging industry representative.
Today, the pvd coating machine has been widely used, especially the plating film, the production of various films are used in various photoelectric systems and optical instruments, Such as digital cameras, digital cameras, telescopes, projectors, energy control, optical communication, display technology, interferometers, satellite missiles, semiconductor lasers, micro-electromechanical systems, information industry, laser production, all kinds of filters, lighting industry, sensors, building glass, automotive industry, decorations, coins, eye lenses, etc. Coating machines have been closely linked with human life.
