Abstract
Abstract A device for electrically interconnecting the wire leads of various electronic elements within a microminiature package. A non-conducting base member having a plurality of electronic element barriers and wire lead through-holes is provided. The through-holes are generally located within the interior regions of the base element to minimize potentially detrimental field interactions or capacitive coupling between the leads and the external package terminals. During package assembly, the electronic elements are placed within recesses created within the base member by the aforementioned barriers. These recesses and barriers align the elements and help maintain electrical separation and uniformity during manufacturing. The wire leads from two or more elements are interconnected by twisting them together and inserting them into one of the through-holes. The leads are inserted into the through-holes such that they protrude below the bottom surface of the base element, thereby facilitating soldering of all such connections in a single process step. This arrangement reduces manufacturing and labor costs and increases component and overall package reliability.
