Abstract:
In combination, a semiconductor chip; a printed circuit board; and bonding wires connecting the chip to the printed circuit board; said printed circuit board comprising a base material, a series of conductive traces of conductive foil on both sides of the base material, the traces on a first surface of the base material forming a first bonding shelf having first bonding pads, the traces on an opposite second surface of the base material forming a second bonding shelf having second bonding pads, said first and second bonding pads being located in rows adjacent to each other separated by said base material, a series of openings in said base material adjacent to said first bonding pads and each leading to a respective one of said second bonding pads on said second bonding shelf, and wherein the bonding wires are connectable directly from the chip to said first bonding pads on said first bonding shelf and through said openings to said second bonding pads on said second bonding shelf.
