  • Patent number: 5567328
    Abstract: A process to manufacture disposable medical flat flexible printed circuits 10. The process entails depositing conductive metal in the range of 1000 to 2500 Angstroms thick onto a flexible film having a thickness in the range of 0.1 to 10 mils. The first portions of the conductive metal are covered with a resist material arranged in a pattern. Metal circuit material is deposited onto second portions of the conductive metal. Overplating the metal circuit material with a corrosion resistant metal. Lastly, removing the resist material and the first portions of the metal and laminating the circuit.
