Parylene Coated Electronics Assemblies

Novara provides a competitive and quality service to cater for all of your Parylene coating requirements.

At Novara, we focus our attention on providing a quality-controlled Parylene conformal coating process to ensure that your product will be protected against the most hostile of environments. This superior conformal coating process creates a moisture barrier and provides electrical insulation to prevent damage of electronics assemblies from contamination such as dust, moisture or chemical attack.

Parylene is the professional choice of conformal coating and can be applied to assembled electronics and components in the instrumentation, aerospace, medical and engineering industries.

Advantages of Parylene Coating

  • Parylene coatings are considered to be completely conformal with the process creating a uniform pinhole free surface of consistent thickness.
  • Parylene is considered to be a green polymer because it is chemically and biologically inert and can be applied at room temperature without any solvents
  • Parylene coating can completely penetrate spaces as narrow as 0.01mm and is therefore suitable for component configurations with sharp edges, points, flat surfaces, crevices.
  • Parylene has excellent electrical properties with a low dielectric constant and high dielectric strength.
  • Parylene coatings adhere to USP Class VI and ISO10993 medical plastics requirements and are also MIL-I-46058C / IPC-CC-830B listed. It is well documented that parylene-coated medical devices can achieve FDA approval.
  • Parylene coatings have exceptional mechanical properties, such as thermal stability over a very wide temperature range (-200°C to +200°C), allowing Parylene coated products to be put into an autoclave.
  • Parylene coating provides an excellent barrier that exhibits a very low permeability to moisture and gases.

Typical Applications for Parylene Coated Electronics Assemblies

Our main focus is the protection of electronic devices and components for the automotive, military, electronics, instrumentation, aerospace, medical and engineering industries.  Here is a brief list of some of the items that can be Parylene coated, this is far from a comprehensive list of items but it should give a good idea:
