What does a vacuum coating machine do? What is its purpose?

The so-called vacuum coating machine process uses evaporation, sputtering, and other methods to emit film material particles in a vacuum environment, which deposit on objects such as metals, glass, ceramics, semiconductors,

Operation process of electron gun evaporation coating

Operation process of electron gun evaporation coating

The density of the electron beam emitted by a high-pressure electron gun is very high. If the electron beam landing point is not properly controlled, the electron beam cannot be deflected onto the metal ingot, which may heat the coating chamber wall and other areas. Therefore,

High frequency discharge in vacuum systems

High frequency discharge in vacuum systems

High frequency discharge is the form of discharge caused by the presence of a high-frequency alternating electric field between two electrons. When an alternating voltage is applied to both ends of the discharge tube, electrons and positive ions in the gas generate additional harmonic vibrations under the action of the alternating electric field.
