  • Electrical substrate material
    Patent number: 4849284
    Abstract: A ceramic filled fluoropolymer-based electrical substrate material well suited for forming rigid printed wiring board substrate materials and integrated circuit chip carriers is presented which exhibits improved electrical performance over other printed wiring board materials and circuit chip carriers. Also, the low coefficients of thermal expansion and compliant nature of this electrical substrate material results in improved surface mount reliability and plated through-hole reliability. The electrical substrate material preferably comprises polytetrafluoroethylene filled with silica along with a small amount of microfiberglass. In an important feature of this invention, the ceramic filler (silica) is coated with a silane coating material which renders the surface of the ceramic hydrophobic and provides improved tensile strength, peel strength and dimensional stability.
    Type: Grant
    Filed: February 17, 1987
    Date of Patent: July 18, 1989
    Assignee: Rogers Corporation
    Inventors: David J. Arthur, John C. Mosko, Connie S. Jackson, G. Robert Traut
