  • Fan-fold shielded electrical leads
    Patent number: 5525760
    Abstract: Fan-folded electrical leads made from copper cladded Kapton, for example, with the copper cladding on one side serving as a ground plane and the copper cladding on the other side being etched to form the leads. The Kapton is fan folded with the leads located at the bottom of the fan-folds. Electrical connections are made by partially opening the folds of the fan and soldering, for example, the connections directly to the ground plane and/or the lead. The fan folded arrangement produces a number of advantages, such as electrically shielding the leads from the environment, is totally non-magnetic, and has a very low thermal conductivity, while being easy to fabricate.
    Type: Grant
    Filed: December 14, 1994
    Date of Patent: June 11, 1996
    Assignee: The United States of America as represented by the United States Department of Energy
