Abstract: A wireless electronic device may be provided with components such as electrical and structural components. During transmission of radio-frequency signals, antennas and wireless communications circuitry of the wireless electronic device may produce associated time-varying magnetic fields. One or more components may be covered with magnetic-resistant shield structures that protect the components from the time-varying magnetic fields by preventing magnetic-induced vibrations. The magnetic-resistant shield structures may include a conductive base layer such a layer of brass. A magnetic-resistant layer may be plated onto the conductive base layer. The magnetic-resistant layer may be formed from an amorphous nickel-phosphorous alloy. The amorphous nickel-phosphorous alloy may be produced by controlling the manufacturing temperature and proportion of phosphorous in the alloy while performing the plating operations within a length of time that ensures non-equilibrium conditions during the plating operations.

Abstract: Electrical components such as integrated circuits may be mounted on a printed circuit board. To prevent the electrical components from being subjected to electromagnetic interference, radio-frequency shielding structures may be formed over the components. The radio-frequency shielding structures may be formed from a layer of metallic paint. Components may be covered by a layer of dielectric. Channels may be formed in the dielectric between blocks of circuitry. The metallic paint may be used to coat the surfaces of the dielectric and to fill the channels. Openings may be formed in the surface of the metallic paint to separate radio-frequency shields from each other. Conductive traces on the surface of the printed circuit board may be used in connecting the metallic paint layer to internal printed circuit board traces.
