Abstract
Abstract An electrical device assembly wherein a plurality of electrical components or conductors having opposing terminal ends are disposed within apertures in a flat dielectric substrate, at least one of the terminal ends of selected components or conductors extending beyond a flat surface of the substrate. Metallic members are affixed to the extending terminal ends of selected components or conductors at one or both of the flat surfaces of the substrate while at least one conductive path is formed on one or both flat surfaces electrically connecting selected ones of the component or conductor terminal ends in a desired manner. The components may be passive components such as electrical resistors, capacitors, inductors, and the like, or active components such as diodes, transistors, and the like. The components and conductors may be maintained within the substrate apertures by means of friction, by means of a dielectric sealing compound, or by means of wedges. The entire assembly is then encapsulated in a suitable dielectric encapsulant, the excess portions of the metallic members are removed, and the members may be bent or otherwise formed in any desired manner as, for example, to form plug-in leads.
