Conformal Coating is a process in which a protective layer of Parylene is applied to electronic circuits and modules to protect against dust, chemicals, extreme temperatures, moisture, and corrosion. Uncoated surfaces are prone to damage and malfunction, hence the added protection becomes necessary for harsh environments.
In contrast to dipping and spraying techniques, the chemical vapor deposition (CVD) provides a vacuum like environment in which the Parylene particles coat all components and points of failure.
Benefits of Conformal Coating (Parylene)
- True conformability with uniform thickness.
- Wide temperature range (-40°C~+85°C)
- Water, corrosion, acid, and base resistance
- Transparency.
- Low friction coefficient
- Insulation characteristic - can withstand voltages.
- Zero stress surface - electrical circuit sensitivity isn’t affected.
- Solvency resistance
- Component alignment - enhance the performance of electronic and mechanical devices.
Certification of coating material:
- USA Military Material Certification MIL-I-46058C.
- NASA Material Certification.
- USP XXII Non-toxic Certification.
- SGS Non-toxic Certification.
- UL94V-0 Fire Safety Certification.
