Abstract
A system includes: a circuit board including electrical elements arranged at a first pitch; a wafer including contacts arranged at a second pitch, where the second pitch is less than the first pitch; and an interconnect including additively-manufactured electrical conduits that are part of an electrical pathway between the electrical elements and the contacts, where the additively-manufactured electrical conduits include electrically-conductive material.
Claims24
A system comprising:
- a circuit board comprising electrical elements arranged at a first pitch;
- a wafer comprising contacts arranged at a second pitch, the second pitch being less than the first pitch;
- and
- an interconnect comprising electrical conduits comprised of layers of material, the electrical conduits being part of an electrical pathway between the electrical elements and the contacts, the electrical conduits comprising electrically-conductive material;
- wherein the electrical conduits have matching electrical impedances, the electrical conduits comprising coaxial structures, the coaxial structures having different physical configurations that produce the matching electrical impedances.
