Conformal Coatings for Microelectronic Components

Modern electronic and microelectronic components are more rugged and mobile than ever and require protection against moisture, corrosion, and temperature extremes. VSI Parylene’s superior dielectric properties, pinhole-free ability to penetrate crevices and multiple layers, and its ultra-thin film which adds minimal mass, give it unparalleled suitability and make it the conformal coating of choice for electronics and LED manufacturers worldwide. Parylene does what other microelectronic coating technologies can’t. It’s inherent barrier properties protect delicate components and devices from dust and debris, fumes, corrosion due to salt water spray, chemicals, or solvents, and more.

Safe for Sensitive and Delicate Components

The nature of the parylene coating process makes it ideal for the most sensitive of components. The vapor deposition process occurs at room temperature, thus there is no curing involved and no thermal or mechanical stresses applied to your components, which ensures their reliability and long product life.
