  • Electrical feedthroughs for ceramic circuit board support substrates
    Patent number: 5681444
    Abstract: Electrical feedthroughs in printed circuit board support substrates for use in making double sided ceramic multilayer printed circuit boards are made by insulating the feedthrough openings with a first layer of nickel oxide and one or more layers of glass, and then filling the remainder of the feedthroughs with a conductive metal via fill ink. After firing, the resultant structure provides insulated electrical feedthroughs through the support substrate.
    Type: Grant
    Filed: July 3, 1996
    Date of Patent: October 28, 1997
    Assignee: David Sarnoff Research Center, Inc.
    Inventors: Thomas Peter Azzaro, Barry Jay Thaler, Edward James Conlon, Ananda Hosakere Kumar
