Abstract:
An electrical system comprising:a. a first substantially planar substrate having a first primary surface, having a first integrated circuit formed in the first primary surface, and having a secondary surface opposite to the first primary surface, wherein a first plurality of integrated circuit electrical contacts are positioned along a first edge of the first primary surface; b. a second substantially planar substrate having a second primary surface, and having a second integrated circuit formed in the second primary surface, the second primary surface having a third edge opposite a second edge, wherein a second plurality of integrated circuit electrical contacts are positioned along the second edge of the second primary surface; and c. an electrical interface for electrically coupling the first plurality of integrated circuit electrical contacts in a face to face relationship with the second plurality of integrated circuit electrical contacts such that the first substantially planar substrate overlaps the second substantially planar substrate only in a region of the first and second integrated circuit electrical contacts but is not substantially overlapping otherwise such that the third edge is substantially unsupported wherein the second substantially planar substrate cantilevers off the edge of the first substantially planar substrate.
