Patent ID: 8156644

Claim:
A method for manufacturing a printed circuit board comprising: providing a printed wiring board with at least one surface trace; mounting at least one component on the printed wiring board; selecting a composition and thickness of each of a dielectric coating and a conductive coating of a conformal electromagnetic interference (EMI) shield such that, when applied to a surface of the printed wiring board having one of said at least one surface trace disposed thereon, said one surface trace has a desired characteristic impedance; applying the conformal EMI shield to the printed circuit board such that the conformal EMI shield conformingly adheres to surfaces of said printed circuit board including said surface of said printed wiring board having said one surface trace disposed therein and such that said dielectric coating has said selected composition and thickness and said conductive coating has said selected composition and thickness, with said dielectric coating being interposed between said conductive coating and said printed circuit board surfaces; mounting a shielded connector on said printed wiring board such that said shielded connector is adapted to be connected to a shielded cable through which signals travel; and mounting a plurality of ground pads in said printed wiring board so as to substantially surround said shielded connector, wherein said conductive coating electrically connects at least one of said plurality of ground pads to a shield of said shielded connector.
