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 far 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.
