Masking is done in accordance with the customer’s drawings and requests for coating keep-out areas. The pin-hole free coatings are conformal, effectually cover crevices, edges, points, sharp ends, internal regions, and there are no gaps at all. With Parylene, the objects you need to coat are placed into a vacuum chamber as part of the chemical vapor deposition (CVD) coating process, and each coating run will have a fixed cost. Parylene can be selectively removed from these substrates with high quality. 25 – 3. In addition to parylene, the substances acrylic, epoxy, silicone and urethane are most commonly used for conformal coating today. 002). Parylene coatings have been used for some time to enhance the lifetime and reliability of electronics made to operate in harsh environments. Parylene is a chemically inert conformal coating [1]. Parylene coating is a vacuum deposition service that involves heating the solid parylene dimer to a vaporous gas state, then re-condensing into a film that deposits onto the target assemblies to be coated. An ultra-thin Parylene film with thickness smaller than 100 nm is usually required to precisely tune the surface property of substrate or protect the functional unit. 5 x 30. The consequent weakened parylene film-to-surface bond, can lead to such causes of parylene failure as (1) bubbles, moisture diffusion and pinholes, (2) corrosion, (3) cracking, (4) delamination, and (5.
