Abstract:
A microelectronic package can include a substrate having a first surface and a second surface opposite therefrom, the substrate having a first conductive element at the first surface, and a plurality of wire bonds, each of the wire bonds having a base electrically connected to a corresponding one of the first conductive elements and having a tip remote from the base, each wire bond having edge surfaces extending from the tip toward the base. The microelectronic package can also include an encapsulation having a major surface facing away from the first surface of the substrate, the encapsulation having a recess extending from the major surface in a direction toward the first surface of the substrate, the tip of a first one of the wire bonds being disposed within the recess, and an electrically conductive layer overlying an inner surface of the encapsulation exposed within the recess, the electrically conductive layer overlying and electrically connected with the tip of the first one of the wire bonds.
