Vacuum coating machine mainly refers to a kind of need to be done under high vacuum coating, including many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition and so on many kinds. The main idea is divided into evaporation and sputtering.
What is a vacuum coating machine? Light coating machine encountering such as to how to solve? Troubleshooting should detect low vacuum is normal (mechanical pump, roots pump, pipe, chamber, evaporator), the low vacuum is normal to open the main pump, main pump work in normal after testing chamber under vacuum is normal, normal to open the high valve chamber under vacuum is used to detect the high vacuum leak detection, vacuum until reach work, limit vacuum, vacuum, vacuum, such as the limit of vacuum and vacuum is normal, and restore the vacuum and vacuum does not work properly may be there is something wrong with the main pump. Now you to what is called vacuum coating machine should have a general understanding.
