How to Make Sure That Your Conformal Coating Actually Conforms

As discussed earlier, it is essentially impossible to achieve a completely uniform coating thickness using a liquid conformal coating. This is really not an issue in most cases as long as the thinnest of areas is capable of maintaining above the minimum thickness for your application.In extreme cases, lack of uniformity can lead to failures. Too thin on vertical surfaces and top component corners can lead to a lack of protection from liquids and gases. Too thick and puddling on inside corners or due to excessive viscosity can result in inadequate drying and curing and then possible cracking during thermal or mechanical shock cycling.
