Abstract
An apparatus and method for shielding discrete areas of a printed circuit board from electromagnetic interference includes a frame and separate shielding lids. The frame is surface mount soldered onto the solder tracks of a printed circuit board and provides fences which divide the printed circuit board into discrete areas. Separate shielding lids of different heights are provided to shield the separate discrete areas. The separate shielding lids mount inside the discrete areas defined by the fences of the frame and attach to lips formed on interior surfaces of the fences.
Claims6
An electromagnetic shielding apparatus for a circuit board having solder traces comprising:
- a) a lid for shielding a discrete area of the circuit board;
- and
- b) a one piece frame unit configured for securement to the solder traces of the circuit board, said frame having continuously connecting fencing extending in an outward direction from the surface of the printed circuit board, said fencing being arranged to surround the discrete area, said fencing having separate interior surfaces each of which surrounds and defines the periphery of the discrete area, said interior surface being configured to retain said lid in the installed position to said fencing to encapsulate the discrete area.
