The application fields of vacuum coating machine are different, and the coating technology used is different. If only pure metal is plated, we can use DC magnetron sputtering technology. If insulating target is plated, I may use more RF magnetron sputtering technology. If only some conventional decorative products are plated, we can use resistance evaporation coating technology, etc. If so many coating technologies are used, can we ensure the effect and quality of vacuum coating machine? The following is how can we ensure the coating effect and quality of the vacuum coating machine.

The vacuum coating machine mainly refers to the coating of a kind of object substrate which needs to be carried out under high vacuum. When plating different substrates and targets, the coating technology is different, and the attention to details is also different, such as the selection, size and shape of target materials, target energization voltage, ion energization current, including the distance between target and substrate, and placement position, which will affect the coating effect and quality. In the coating process, in order to ensure the pure plating of the coated film, we also need to clean the residual impurities and gas pressure on the substrate surface, which has a great influence on the coating effect and quality. The target and substrate are different, the coating technology is different, and the attention is different. These considerations are relatively deep.

Generally speaking, engineers who operate vacuum coating machines may not think so deeply, but may consider some simple and external factors. For example, the surface of the coated material is treated with dust. After the vacuum coating machine is used for a period of time, the equipment must be cleaned and maintained, and the operators and operating requirements should be standardized, including wearing professional clothing, gloves and foot covers. Strictly handle the substrate materials to be clean and meet the process requirements. The source material meets the necessary purity requirements. Ensure that facilities, equipment and operating environment are clean. For example, the environmental requirements of materials and sample places, environmental temperature and humidity requirements, etc. Reduce the low fluidity of indoor air in vacuum coating equipment, minimize the invasion of outdoor dust and so on.
