Abstract: A component can include a generally planar element, a reinforcing dielectric layer overlying the generally planar element, an encapsulation overlying the reinforcing dielectric layer, and a plurality of wire bonds. Each wire bond can have a tip at a major surface of the encapsulation. The wire bonds can have first portions extending within the reinforcing dielectric layer. The first portions of at least some of the wire bonds can have bends that change an extension direction of the respective wire bond. The reinforcing dielectric layer can have protruding regions surrounding respective ones of the wire bonds, the protruding regions extending to greater peak heights from the first surface of the generally planar element than portions of the reinforcing dielectric layer between adjacent ones of the protruding regions. The peak heights of the protruding regions can coincide with points of contact between the reinforcing dielectric layer and individual wire bonds.

Abstract: A structure includes a substrate having a first region and a second region, the substrate also having a first surface and a second surface. Electrically conductive elements are exposed at the first surface within the second region. Wire bonds have bases bonded to respective ones of the conductive elements and ends remote from the substrate and remote from the bases. At least one of the wire bonds has a shape such that the wire bond defines an axis between the free end and the base thereof and such that the wire bond defines a plane. A bent portion of the at least one wire bond extends away from the axis within the plane. A dielectric encapsulation layer covers portions of the wire bonds such that unencapsulated portions, including the ends, of the wire bonds are defined by portions of the wire bonds that are uncovered by the encapsulation layer.

Abstract: A microelectronic package includes a substrate having a first surface. A microelectronic element overlies the first surface. Electrically conductive elements are exposed at the first surface of the substrate, at least some of which are electrically connected to the microelectronic element. The package includes wire bonds having bases bonded to respective ones of the conductive elements and ends remote from the substrate and remote from the bases. The ends of the wire bonds are defined on tips of the wire bonds, and the wire bonds define respective first diameters between the bases and the tips thereof. The tips have at least one dimension that is smaller than the respective first diameters of the wire bonds. A dielectric encapsulation layer covers portions of the wire bonds, and unencapsulated portions of the wire bonds are defined by portions of the wire bonds, including the ends, are uncovered by the encapsulation layer.
