A conformally coated structure includes a component of an electronic assembly, such as a microelectronic device, a part of a package, or an electrically conductive trace, and a conformal coating applied to a surface of the structure. The conformal coating is a cured polymer blend of a base polymer and an electrically conductive polymer. The polymer blend has an electrical resistivity of from about 109 to about 1013 ohm-centimeter. The polymer blend contains from about 0.5 percent to about 4 percent by weight of the electrically conductive polymer, with the remainder the base polymer. The electrically conductive polymer may be a polyaniline, and the base polymer may be a urethane. |
