Abstract:
1. A method of making a microelectronic package comprising: assembling a microelectronic element with a substrate so as to overlie a top surface of a substrate, said microelectronic element having an outer perimeter, faces and contacts accessible at one or more of the faces, the substrate having a plurality of conductive traces extending along at least one of the top surface or a bottom surface opposite thereto, the traces being conductively connected with said microelectronic element; a plurality of substantially rigid conductive posts exposed at the bottom surface of said substrate, said conductive posts including outermost ones disposed closest to said outer perimeter of said substrate, wherein said conductive traces and said posts have a structure formed integrally and subtractively from the same metal structure; and forming a protective layer in contact with said microelectronic element and overlying said substrate, wherein said protective layer extends outwardly beyond outermost ones of said conductive posts.
