Abstract:
A plurality of shields for shielding each one of a plurality of selected electronic components and of selected electronic sub-assemblies disposed on a printed wiring board assembly from electromagnetic interference (EMI) and/or from radio frequency interference (RFI), the shields comprising:open-ended electrically conductive casings having sidewalls extending between lower ends and upper ends of the casings;the lower ends of the casings fixedly attached on the printed wiring board assembly so as to surround the selected electronic components and the selected electronic sub-assemblies;a compliant electrically conductive member having a lower surface and an upper surface, the lower surface disposed in common over the upper ends of the casings;an electrically conductive housing having disposed over the upper surface of the compliant member, a surface of the housing providing compression of the compliant member such that electrical contact is maintained between the housing and the upper ends of the casings; andan electrically conductive base plate spaced from the wiring board assembly and connected to an electrical ground potential, the housing removably attached to the base plate to provide the plurality of shields when the housing is attached to the base plate, and alternatively to provide access to the selected electronic components and to the electronic sub-assemblies through the upper ends of the casings when the housing is removed from the base plate and the compliant member is removed from the upper ends of the casings.
