Appropriately selected and applied, conformal coatings provide essential working protection for printed circuit boards (PCBs). However, removal of conformal coatings is necessary if the wrong coating material is selected relative to the PCB’s functional requirements, inadequately supporting its operating environment. Poor coating application can trigger failure mechanisms within the assembly, al
Conformal coatings differ in their material-specific performance properties as protective films for electronic assemblies. Knowing the operational characteristics of various coating-types and their functional association with assembly components supports successful film application. Issues that confound conformal coating selection and application result from potential post-application problems lik

Operationally, conformal coatings are applied to the surface of PCBs and related electrical components, to insulate and protect them during use. Coatings improve PCBs’ performance under any circumstances, but are especially valuable for their functional tolerance to harsher working environments.
