A microelectronic package has a microelectronic element 110 overlying or mounted to a first surface 102 of a substrate 100 and substantially rigid conductive posts 106 projecting above the first surface or projecting above a second surface 104 of the substrate remote therefrom. Conductive elements 108 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 130 overlies at least a portion of the microelectronic element 110 and the surface 102 of the substrate 100 above which the conductive posts 106 project, the encapsulant having a recess 336 or one or more openings 136, 236 each permitting at least one electrical connection to be made to at least one conductive post. At least some conductive posts 106 are electrically insulated from one another and adapted to simultaneously carry different electric potentials. In particular embodiments, the openings 136, 140, 146, 236 in the encapsulant 130 at least partially expose conductive masses 144 joined to posts, fully expose top surfaces 126 of posts 106 and partially expose edge surfaces 138 of posts, or may only partially expose top surfaces 126 of posts. |
