  • Multilayer via resistors
    Patent number: 4300115
    Abstract: A substrate has two or more conductive layers deposited thereon, each adjnt layer pair separated by a dielectric layer. Apertures are formed in the dielectric layer and are filled with resistor paste. In this way, a resistive path may be formed between the conductive layers. This concept of fabricating resistors are particularly useful in the inclusion of pull-up, pull-down and other non-critical resistors in the circuitry contained within a thick film construction.
    Type: Grant
    Filed: June 2, 1980
    Date of Patent: November 10, 1981
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Joseph L. Ansell, Raymond J. Baker
  • Method for making thick film capacitors
    Patent number: 4007296
    Abstract: A method for making precision thick film capacitors is described. A conduve pattern is printed on both sides of a substrate such that the two patterns at least partially overlap. A capacitor of predetermined value is obtained by calculating and providing the area of overlap necessary for such value of capacitance.
