Abstract:
A multilayer capacitance structure suitable for a core in a circuit board comprising:a first layer of electrically conducting material defining a central conducting plane having first and second opposite faces and at least one clearance hole therethrough; a first layer of organic dielectric material on said first face of said central conducting plane and a second layer of organic dielectric material on said second face of said central conducting plane, said dielectric material including an organic resin; and a second layer of conductive material on said first layer of dielectric material defining a first exterior plane, and a third layer of conductive material on said second layer of dielectric material defining a second exterior plane, a plated through hole formed through said at least one clearance hole in said central conducting plane and through said first and second layers of dielectric material to connect said two external conducting planes.
