Abstract:
1. A multi-chip module in an electronic device comprising: a printed circuit board having a surface having a first plurality of flip-chip pads thereon and a second plurality of wire-bondable pads thereon, at least one flip-chip pad of the first plurality of flip-chip pads connected to at least one wire bondable pad of the second plurality of wire-bondable pads on the surface of the printed circuit board; a first integrated circuit die having opposing front-side and back-side surfaces, the front-side surface having a plurality of flip-chip bumps thereon and at least one flip-chip bump of the plurality of flip-chip bumps connected to at least one flip-chip pad of the first plurality of flip-chip pads on the surface of the printed circuit board; a second integrated circuit die having opposing front-side and back-side surfaces, the back-side surface of the second integrated circuit die attached to the back-side surface of the first integrated circuit die and the front-side surface of the second integrated circuit die having a plurality of bond pads thereon; and at least one wire connection between at least one bond pad of the plurality of bond pads on the front-side surface of the second integrated circuit die and the at least one wire-bondable pad of the second plurality of wire-bondable pads on the surface of the printed circuit board for connecting the same circuit of the first integrated circuit die and the second integrated circuit die on the printed circuit board.
