Patent ID: 8315678

Claim:
A multilayer superconducting printed circuit board, comprising: a first electrically insulative substrate layer having a first surface and a second surface opposed to the first surface, wherein the first electrically insulative substrate layer has at least a first hole that extends from the first surface to the second surface and wherein at least a portion of an inner surface of the first hole is coated with a binder material; at least a second electrically insulative substrate layer having a first surface and a second surface opposed to the first surface, the second electrically insulative substrate layer physically coupled to the first electrically insulative substrate layer; a first superconducting current path consisting of an elemental or alloyed superconducting metal positioned on a first surface side of the first electrically insulative substrate layer; a second superconducting current path consisting of an elemental or alloyed superconducting metal positioned between the first and the second electrically insulative substrate layers; and a third superconducting current path that extends through the first hole in the first electrically insulative substrate layer and superconductingly couples the first superconducting current path with the second superconducting current path, wherein the third superconducting current path consists of an elemental or alloyed superconducting metal plated on at least a portion of the binder material on the inner surface of the first hole.
