Abstract

A method of bonding a superconductive ribbon lead to a superconducting bonding pad connected to superconducting circuitry. The thin ribbon is first coated with a fresh layer of the same material from which it is made and then a very thin layer of a noble metal is applied over that fresh layer. The bonding pad is also prepared with a very thin layer of the noble metal. Those coated surfaces are placed in facing contact and ultrasonically bonded.
