First Claim
1. A microelectronic package comprising:
- a substrate having a first surface and a second surface remote from the first surface;
a microelectronic element overlying the first surface;
substantially rigid conductors projecting above at least one of the first or second surfaces;
a conductive bond metal contacting surfaces of the conductors and extending downwardly from apexes thereof towards the at least one surface of the substrate;
conductive elements exposed at a surface of the substrate opposite the surface above which the conductors project, the conductive elements being electrically interconnected with the microelectronic element; and
an encapsulant overlying at least a portion of the microelectronic element and the surface of the substrate above which the conductors project, the encapsulant having a plurality of openings through which the bond metal is exposed, wherein at least some of the conductors are electrically insulated from one another and adapted to simultaneously carry different electric potentials.

Abstract
A microelectronic package has a microelectronic element overlying or mounted to a first surface of a substrate and substantially rigid conductive posts projecting above the first surface or projecting above a second surface of the substrate remote therefrom. Conductive elements exposed at a surface of the substrate opposite the surface above which the conductive posts project are electrically interconnected with the microelectronic element. An encapsulant overlies at least a portion of the microelectronic element and the surface of the substrate above which the conductive posts project, the encapsulant having a recess or a plurality of openings each permitting at least one electrical connection to be made to at least one conductive post. At least some conductive posts are electrically insulated from one another and adapted to simultaneously carry different electric potentials. In particular embodiments, the openings in the encapsulant at least partially expose conductive masses joined to posts, fully expose top surfaces of posts and partially expose edge surfaces of posts, or may only partially expose top surfaces of posts.
