Abstract
A coated electronic assembly comprises an electronic assembly, and a single-layer conformal coating overlying at least a portion of the electronic assembly. The conformal coating has a volume electrical resistivity of from about 10,to about 10,ohm-centimeter. The conformal coating is formed of an organic polymeric binder, and a plurality of electrically semiconductive metal oxide filler particles dispersed in the binder. The binder and the filler particles have substantially the same visible-light refractive index. The binder may be a heat-curable or UV-curable urethane, and the particles may be doped (Al,Mg,Zn),O,or doped ZnO.
