As electronic assemblies get smaller and more widespread, conformal coating is becoming increasingly popular - because it can make the difference between premature failure and successful operation throughout required lifespan of the device. Conformal coatings are often regarded as a vital component of a circuit assembly. While they may not always perform a particular electrical function, they are the most effective way to increase circuit lifespan in harsh or rough service environments.
Use of conformal coatings is expanding. Growth areas include mobile devices, where smaller circuits have to withstand shock and elevated humidity levels, automobiles, where sensors are progressively positioned throughout new vehicles and medical devices, where functionality is critical.
