Patent ID: 11398770

Abstract:
Encapsulated electronic modules having complex contact structures may be formed by encapsulating panels containing a substrate comprising pluralities of electronic modules delineated by cut lines and having conductive interconnects buried within terminal holes and other holes drilled in the panel within the boundaries of the cut lines. Slots may be cut in the panel along the cut lines. The interior of the holes, as well as surfaces within the slots and on the surfaces of the panel may be metallized, e.g. by a series of processes including plating. Solder may be dispensed into the holes for surface mounting. Two or more panels may be stacked prior to singulation to form module stacks. Multi-cell converters having a large cell pitch may be combined with an interconnection module to provide vertical power delivery to semiconductor devices through a semiconductor power grid having a small pitch. The converters and interconnection modules may be fabricated in panels and stacked prior to singulation.
