Abstract:
1. A microelectronic assembly comprising: a substrate having a top surface, a bottom surface and a first edge extending between said top surface and said bottom surface, said substrate having a plurality of bonding contacts exposed at said top surface and a plurality of terminals, said substrate further having a plurality of traces connecting at least some of said bonding contacts to at least some of said plurality of terminals, at least some of said plurality of traces extending adjacent said first edge of the substrate so that said at least some of said plurality of traces are disposed between at least some of said bonding contacts and said first edge; and a first microelectronic element underlying said substrate such that said bottom surface of said substrate faces toward said first microelectronic element, said first microelectronic element having contacts, at least some of said contacts being connected to at least some of said plurality of bonding contacts by wire leads, wherein at least some of said wire leads extend from at least some of said bonding contacts exposed at said top surface, over at least some of said plurality of traces and are not conductively connected with said at least some of said plurality of traces, and wherein said wire leads extend beyond said first edge to said contacts of said microelectronic element below said bottom surface of said substrate.
