Coating equipment is a device that melts and evaporates metal aluminum at high temperature under high vacuum, so that aluminum vapor is deposited and deposited on the surface of the plastic film, so that the surface of the plastic film has a metallic luster. Vacuum coating technology, as a technology to produce a specific film, has a wide range of applications in real production and life.
Coating methods of coating equipment: ion plating, evaporation plating, sputtering plating.
(1) The characteristics of the coating equipment: the film formation speed is 0.1-50um/min, the equipment is relatively simple, and the operation is easy; the purity of the film is high; the film growth mechanism is relatively simple.
(2) Disadvantages: film adhesion is small, crystallization is not perfect, and process repeatability is not good enough.
What's the reason for the film drop of the product plated by the coating equipment?
1. The product surface is not clean enough, and the ion source cleaning argon will take longer to amplify.
2. If cleaning agent is added or replaced, it is recommended to try it with pure water first.
3. Whether there is any change in the process parameters, some adjustments can be made in the film thickness and current.
