Abstract:
1. A substrate for receiving a die-down die and providing electrical contacts re-orientated into a die-up orientation, the die-down die defining electrical contacts, the substrate comprising: a plurality of electrically conductive traces defining first contacts, the first contacts arranged in an orientation to accept connector wires for making electrical connections from the electrical contacts of a single die-down die, if one was mounted, the plurality of electrically conductive traces running under and from one side to the opposite side of a single die down die, if one was mounted, and wherein the electrical traces define second contacts located on the opposite side relative to the first contacts, the second contacts arranged in a die up orientation, wherein the substrate can be placed into a package designed to accept a single die-up die, and wherein electrical connections may be made to the substrate's contacts as if it were a single die-up die.
