Abstract
A plurality of shields is provided for shielding selected electronic components and electronic sub-assemblies mounted on a printed wiring board assembly from electromagnetic interference (EMI) and/or from radio frequency interference (RFI). The shields include open-ended electrically conductive casings having lower ends fixedly attached on the printed wiring board so as to surround selected components. A compliant electrically conductive member is positioned in common over upper ends of the casings. An electrically conductive housing disposed over the compliant member provides compression of the compliant member such that electrical contact is maintained between the housing on the upper ends of the casings. A grounded base plate is spaced from the wiring board assembly. The housing is removably attached to the base plate to provide the plurality of shields. Access to the components and sub-assemblies is obtained by removal of the housing from the base plate and by removal of the compliant member from the upper ends of the casings.
