How to reduce dust in vacuum coating

A layer of dust on the coating surface will affect the overall effect of vacuum coating. How to reduce dust?

1. The source material used shall meet the necessary purity requirements.

2. After the sample is taken out, the environment should be kept clean.

3. After coating for a period of time, the inner wall of the vacuum chamber must be cleaned.

4. The cleaning of the substrate material must strictly meet the process requirements.

5. The staff has special clothing, and the operation should wear gloves, foot covers, etc.

6. Properly increase the humidity of the environment, which is beneficial to reduce the suspended solid particles in the surrounding environment.

7. What is the upper limit of the maximum particle size and the number of particles per unit area that are clearly allowed by technology?

8. The indoor air has low mobility and the floor is clean. If it is a bare concrete floor, it needs to be covered. Walls and roofs cannot be painted with general grey paint.

Large Multi-Arc Ion Vacuum Coating Machine

Large multi arc ion plating introduces various gas discharge modes into the field of vapor deposition under vacuum situation. The whole vapor deposition process is carried out in plasma process. It can be coated not only on the surface of metal products, but also on the surface of non-metal products. It can be plated with metal film, Titanium nitride, titanium carbide, zirconium nitride, chromium nitride, titanium oxide and other films.
