ABSTRACT:
A flexible media having a plurality of electrical conductors extending radially outward from a central portion thereof with insulative material interposed between adjacent conductors. Radially inward portions of selected ones of the conductors are placed in contact with respective ones of a first set of electrical components disposed in a first predetermined pattern and radially outward portions of the selected conductors are placed in contact with respective ones of a second set of electrical components disposed in a second predetermined pattern, the second set of components being spaced farther apart than the first set of components. In one embodiment the media is comprised of a circular elastomer material having electrical conductors disposed at equal angular intervals over the circumference of the material. The first set of electrical components is comprised of a plurality of electrical bond pads arranged in a circular pattern on a major surface of an electronic device, such as an integrated circuit chip, and the second set of components is comprised of a plurality of printed circuit conductors disposed on an insulative substrate, which extend radially inward toward the bond pads. In another aspect of the invention, the printed circuit conductors are formed directly on an inner major surface of an insulative casing, within which the primary components of an electronic apparatus are contained, thereby eliminating the need for a separate printed circuit board component.
