Conformal coatings are a protective barrier or film, layered over the sensitive electronic components. When applied accurately, 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.
