Abstract:
1. A connection component for mounting a microelectronic element, said connection component comprising: (a) a dielectric layer having an upwardly-facing inside surface and a downwardly-facing outside surface; (b) electrically conductive traces extending on said dielectric layer remote from said outside surface; (c) electrically conductive posts extending from said traces through said dielectric layer and projecting downwardly by post projection distances beyond said outside surface of said dielectric layer, wherein each post has a bottom surface joined to each trace, a top surface remote from said bottom surface, and an edge surface connecting said top and bottom surfaces; and (d) electrically conductive pads extending from said traces through said dielectric layer and projecting downwardly by pad projection distances beyond said outside surface of said dielectric layer, said pad projection distances being less than said post projection distances, at least some of said pads being electrically connected to at least some of said posts by at least some of said traces.
