Claim:
1. A microelectronic assembly comprising: a substrate having a first surface and a conductive element exposed at the first surface; a wire bond having a base bonded to the conductive element and an end surface a predetermined distance from the base, the end surface including an end portion having a cross-section wider than a cross-section of the wire bond; and a dielectric encapsulation layer overlying the first surface of the substrate, wherein the dielectric encapsulation layer at least partially covers the first surface of the substrate and a portion of the wire bond, such that an unencapsulated portion of the wire bond is defined by a portion of the end portion, wherein the wire bond has a first edge surface defined between the base and the end portion, the end portion has a second edge surface that extends outward from the first edge surface of the wire bond below a major surface of the dielectric encapsulation layer, and the dielectric encapsulation layer surrounds the second edge surface.
