Abstract
A shielding gasket is affixed to a shield housing for interposition between the shield housing and a circuit board of an electronic device. The circuit board includes a plurality of electronic components and related circuitry and the arrangement of the shield housing and the shielding gasket provide for inter-component shielding of the plural electronic components from one another, together with corresponding related circuitry, as well as overall shielding of the plural electronic components on the circuit board. To that end, the shielding gasket includes partitions integral with the shielding gasket for extending between the electronic components, the partitions engaging the shield housing such that the shield housing and the partitions complete inter-component shielding of the electronic components and related circuitry from one another.
