Parylene Coating As commonly used in the medical industry, parylene coating refers to an organic coating material with a polycrystalline or linear structure. The parylene coating is very thin, smooth, chemically inert and has dielectric properties. In addition, parylene can perfectly conform to the matrix because it can adhere to it molecule by molecule. The coating has many uses, for example, because of its biocompatibility, medical devices can be implanted in the body with less resistance. Ultrasonic spray deposition polymerization Ultrasonic spraying can effectively deposit the parylene layer. Ultrasonic spraying has advantages in dealing with complex geometries and can ensure complete coverage of all product surfaces without orange peel. The soft atomized spray can adhere well to the surface, and the morphological characteristics of the coating can be adjusted by modifying the process parameters. High-pressure spraying and air atomizers cannot apply the coating uniformly like ultra...
