What Are Conformal Coatings?

Conformal coatings are a protective barrier or film, layered over the sensitive electronic components. When applied accurately, waterproof conformal coatings prevent sources of moisture and vapors from damaging or corroding your product’s interior circuitry. Consider conformal coatings a step above mechanical seals and enclosures. These polymeric films use unique chemical formulas and structures to block potentially harmful substances.

Think of it as a precision vacuum-seal for the interior components of a device. Conformal coatings tightly wrap around the geometry of complex parts. Rather than preventing ingress with the bulk of enclosures, conformal coatings form a tight bond that’s much thinner — typically down to micrometers.

Conformal coatings for electronic applications are used in a variety of industries, from military to automotive, to industrial and IoT. Whether in the field or at home, conformal coatings help to ensure machinery and devices stay functional and online through the most unpredictable conditions. 

How Are Conformal Coatings Applied?

An operator or machine can treat a circuit board by brushing, dipping, or spraying on a material. With liquid-based methods of application, however, there can be accidental bubbling or pooling. At HZO, we utilize chemical vapor deposition (CVD). This method of coating is more uniform and conformal than brushed, dipped, or sprayed liquids. Our conformal coating company also specializes in conformal coating masking to ensure that parts of a PCBA or component where you don’t want a coating to be applied are covered. The purpose of the conformal coating masking is to prevent migration of the conformal coatings into components and keep out areas.

After the conformal coating application process, most waterproof conformal coatings need time to cure and correctly set. While, in some cases, air-drying is enough, it’s a slow and inconsistent method. Other coatings need to react to heat from an oven chamber or exposure to UV light. Because CVD, a machine-driven, repeatable process does not require curing or heat, components are ready to move to production within a shorter time. HZO equipment speeds up time and improves the volume of prepared batches, moving parts more quickly into the next stage of manufacturing.
