Abstract
Process for manufacturing a high interconnection density, fine-line, superconductive printed leadframes using thick-film screen-printing techniques, or other printing techniques. Generally, a superconductive leadframe pattern is printed on a backing substrate. Once the pattern is cured, the backing substrate, or portions thereof can be removed. The backing substrate can be a 'fish paper' substrate treated with a release agent, or other substrate material which can be dissolved away, etched away, or otherwise removed. Portions of the backing substrate can be used to provide mechanical integrity for the leadframe. The leadframe fingers can be printed using a superconductive paste or a superconductive precursor paste which is subsequently treated to exhibit superconductivity.
