A reliable superconducting contact for superconducting thin film components, based on soft superconducting materials, and a method for making the contacts. The joint, according to this invention, consists of a thin bonding slab having its end longitudi- nally cut so that double or multiple parallel joints can be made. In the method, a wire blank is squeezed to a thin plate and then this plate is cut to slabs used in the bonding. The ribbon-like character and the thinness of the bonding slab permit a precise control of the bonding temperature and reduce the strain and bending forces caused by thermal contraction, preventing the contact from peeling off while cool- ing the superconducting component to the operational temperature. Corresponding prior-art methods have proven unreliable especially on such applications where the simultaneous faultless operation of several tens of contacts is essential.
