Abstract:
Methods and apparatus for providing conformal shielding are disclosed to provide electromagnetic interference shielding of circuit components mounted on a circuit board. A print mold stencil is provided with one or more conductive shielding walls disposed within the stencil before its application to the circuit board and detachable therefrom, and also configured to encompass the circuit components. In this manner a shielded compartment volume is defined by walls of the print mold stencil and one or more of the conductive shielding walls, and may be easily and quickly applied to the circuit board to encompass the components for shielding. A conformal shielding layer is then formed from a molding material disposed in the shielded compartment volume that encompasses the components, as well as a conductive layer disposed on the outer surface of the material, and coupling of the shielding walls with a ground plane in the circuit board.
