How to detect the performance of the vacuum coating equipment?

         

  Vacuum coating equipment is used for the preparation of vacuum membrane equipment, vacuum coating equipment has a significant impact on performance of film, so, how to detect the performance of the vacuum coating equipment? Underneath, small make up teach you how to detect the performance of the vacuum coating equipment.
1, after coating with coating equipment, film base material of the thin film on the edge of the drum is not uniformity should be less than or equal to 1 cm.
2, the homogeneous degree of the film in terms of lateral change value is around 10%.
3, put film base material from the position of the fluorescent lamp 50 cm, with fluorescent detection without scars.
4, different film plating system, requirements are different, but are generally not required at most only one pinhole within 1 square meters. Pinhole is due to the deposition in the process of small aluminum droplet splash on the substrate.
