  • Shielded flexible circuits and methods for manufacturing same
    Patent number: 7645941
    Abstract: A shielded flexible cable having a plurality of shielded electronic circuits in close proximity to one another such that signals transmitted on one of said plurality of shielded electronic circuits do not substantially interfere with signals transmitted on the other of said plurality of electronic circuits comprising a polyimide support member supporting a plurality of etched copper traces on a first side of said polyimide support member and a copper layer on a second side of said polyimide support member; said polyimide support member flexible along at least one axis; said plurality of etched copper traces and said copper layer substantially as flexible as said polyimide support member; a silver based material, including, for example, silver ink or silver film, surrounding a portion of each of said plurality of copper traces along substantially the entire length of each of said plurality of copper traces; said silver based material in electrical communication with (i) said copper layer via discontinuities in
