Patent ID: 7132357

Claim:
A method for shielding one or more circuits of a printed circuit board wherein said one or more circuits are printed on a substrate, comprising the steps of: depositing a layer of dielectric material over the substrate and over the one or more printed circuits thereon; creating a trench-like opening in the dielectric layer such that the trench-like opening surrounds the one or more circuits to be shielded; depositing a layer of metal over the layer of dielectric material and within the trench-like openings; creating a solder pad at each location where an electrical connection is to be made to the one or more printed circuits by removing a border of the metal layer surrounding each connection location, thereby leaving a portion of the metal layer within the border at the connection locations; and providing a microvia through each solder pad penetrating the dielectric layer and terminating at the metal of the printed circuit.
