  • Patent number: 5708569
    Abstract: A circuit component assembly and a method for forming the assembly as an annular body in a laminate, preferably between a trough-hole or via and a surrounding conductive layer in a PCB are disclosed, the circuit component assembly including one or more resistors/conductors, inductors and dielectrics/capacitors or combinations thereof, outer and inner peripheries of the circuit component preferably having substantially constant radii permitting simple determination of operative electrical characteristics for the circuit component from (a) the inner and outer radii, (b) an effective thickness for the circuit component and (c) its electrical characteristics determined by the material formed in the annular recess, the circuit component body preferably being formed from a liquid precursor forming conductive interconnections for the circuit component assembly at its outer and inner perimeters.
    Type: Grant
    Filed: July 8, 1996
    Date of Patent: January 13, 1998
    Assignee: Zycon Corporation
    Inventors: James R. Howard, Gregory L. Lucas, Scott K. Bryan, Jin S. Choe, Nicholas Biunno

  • Patent number: 5347258
    Abstract: A resistor and method of forming the resistor as an annular resistor body between a conductive pad surrounding a through-hole in the PCB and a surrounding conductive layer, the annular resistor body being formed from a conductive material having a selected resistivity, the outer and inner perimeters of the annular resistor body preferably being substantially constant radii whereby the operative resistance of the annular resistor body may be simply determined from the radii of its outer and inner perimeters, an effective thickness of the annular resistor body and its resistivity, the annular resistor body more preferably being formed from a liquid precursor facilitating formation of conductive interconnections at its outer and inner perimeters.
