Abstract:
1. A method for electrically interconnecting an electrical device to a substrate module comprising the steps of: solder bonding the electrical device onto the substrate module with a bottom surface of the electrical device making a first electrical interconnection between a third input/output port of the electrical device and the substrate module; bonding a first conductive foil element comprising a substantially uniform layer of conductive material to a first conductive device surface disposed on a top surface of the electrical device and associated with a first input/output port; bonding the first conductive foil element to a first conductive substrate surface disposed on the substrate module, wherein the first conductive foil element provides a substantially continuous conductive path extending between the first conductive device surface and the first conductive substrate surface thereby making a second electrical interconnection between the first input/output port of the electrical device and the substrate module; bonding a second conductive foil element comprising a substantially uniform layer of conductive material to a second conductive device surface disposed on a top surface of the electrical device and associated with a second input/output port of the electrical device; and, bonding the second conductive foil element to a second conductive substrate surface disposed on the substrate module, wherein the second conductive foil element provides a substantially continuous conductive path extending between the second conductive device surface and the second conductive substrate surface thereby making a third electrical interconnection between the second input/output port of the electrical device and the substrate module; wherein the first conductive foil element includes at least one raised ridge configured to extend up and over the second conductive substrate surface such that the first conductive foil element avoids electrical contact with the second conductive substrate surface, and wherein a space between the ridge and the second conductive substrate surface ridge is filled with an electrically insulating material.
