Conformal coatings are needed to insulate and extend the lifespan of your PCBs and other intricate electrical components. As a global leader in conformal coating services, Plasma Ruggedized Solutions provides you with the most effective NADCAP, AS9100 and NASA-certified coating services available. Additionally, our extensive knowledge in the protection of circuit board assemblies allows us to protect your circuitry to Federal Information Processing Standards (FIPS).

Vapor Deposition involves using a chemical vacuum polymerization process to effectively seal your PCBs with a uniform Parylene coating. Vapor Deposition Parylene coatings can also be applied in conjunction with other coating methodologies for superior protection. We can perform vapor deposition processes to add Parylene coatings to your LED components. Our Parylene vapor deposition coating method provides true pinhole-free circuit board coatings that allow for complete protection from impact in addition to the following:

  • Electrical leakage
  • Exposure to moisture
  • Salt, Fog and other corrosive threats
  • Temperature fluctuation, Shock and Vibration
  • Fungus
  • Dust

Plasma Ruggedized Solutions can assist you from the design stages onward to help make the PCB/LED coating process easier and more effective.

An Innovative Method For Parylene Coating

Parylene conformal coating is applied using a vacuum deposition process, also known as polyparaxylylene coating, that involves heating the solid Parylene dimer to a vaporous state, then re-condensing it on the target assemblies to be coated. The vapor deposition process allows Parylene coatings to be uniform in thickness and completely pinhole free with a dielectric strength exceeding 6000 volts per mil. Vapor Deposition coatings are suitable for a variety of industries, including:

Chemical Vapor Deposition Coating Advantages

Chemical vapor deposition Parylene coatings for LED’s feature excellent light transmission properties, and, thanks to our specialized application process, coat almost every possible surface for superior protection. The vapor deposition process creates a completely even coating with extremely low permeability for added moisture, chemical, and solvent protection.

Vapor deposition is an extremely intricate PCB protection method, which makes this process ideal for smaller batches in which a more intricate Parylene layer is required.
