Abstract
Abstract An encapsulated electronic module including a nonconductive substrate having attached thereto a plurality of electrical components and an electrical network of connectors attached to the substrate and forming termination pads adjacent the edges of the substrate to which leads are attached. A flat cover is disposed over the substrate but spaced therefrom; the cover having a hole formed therethrough through which an encapsulation material is inserted between the substrate and cover completely filling the space therebetween. The encapsulation material extends at least partially into the opening in the cover member thereby securely attaching the cover member to the base member and sealing the space between these members.
