Patent attributes
An electronic device may have a printed circuit to which electrical components are mounted. Electromagnetic shields may be mounted to the printed circuit over the components to suppress interference. A shield may have a metal frame covered with a conductive fabric. The conductive fabric may cover an opening in the top of the frame. An insulating layer may be formed on the lower surface of the conductive fabric to prevent shorts between components on the printed circuit and the conductive fabric. An insulating cap such as an elastomeric polymer cap may also be formed over each component to provide electrical isolation between the components and the conductive fabric. Shields may be formed by coupling shield cans to subscriber identity module shields or other metal structures in a device. Intervening wall structures may be removed to help provide additional shielding volume.
