    Abstract: A multi-layer capacitor such as a multi-layer-ceramic-capacitor (MLCC) has upper and lower dielectric layers separating upper and lower electrode layers, where the lower dielectric layers have a lower dielectric constant than the upper dielectric layers to reduce piezoelectric effect driven capacitor reaction forces on a printed circuit board (PCB) on which the capacitor is mounted. Such an MLCC may include the upper dielectric and electrode layers in a top portion of the MLCC; and the lower dielectric and electrode layers in a bottom portion of the MLCC. A bottom portion of the MLCC may be mounted on a PCB. As an example, the dielectric constant value of the lower dielectric layers may be between 1.5 and 3.5 times less than that of the upper dielectric layers to reduce piezoelectric effect driven capacitor reaction forces in the audio range of human hearing. Other embodiments are also described and claimed.

    Abstract: A Non-Uniform Dielectric Layer, Multi-Layer-Ceramic-Capacitor (MLCC) has upper and lower dielectric layers separating upper and lower electrode layers, where the lower dielectric layers have a greater vertical thickness than the upper dielectric layers to reduce piezoelectric effect driven capacitor reaction forces on a printed circuit board (PCB) on which the capacitor is mounted. Such an MLCC may include an upper set of dielectric layers that separate adjacent pairs of upper electrode layers in a top portion of the MLCC, and a lower set of dielectric layers that separate adjacent pairs of lower electrode layers in a bottom portion of the MLCC. A bottom portion of the MLCC may be mounted on a PCB. The thickness of the lower dielectric layers may be between 1.5 and 3.5 times greater than the upper dielectric layers to reduce piezoelectric effect driven capacitor reaction forces in the audio range of human hearing.

    Abstract: An electronic device may have a source of magnetic field such as a magnet that produces a static magnetic field. A flexible printed circuit may have a flexible tail that surrounds a central portion. The central portion may overlap the magnet. Electrical components may be mounted to the central portion. To prevent undesired vibrations and noise due to interactions between magnetic fields induced by signals flowing in signal lines in the flexible printed circuit and the static magnetic field, the signal lines may be vertically stacked or may be routed along a curved path that does not overlap the magnet. The tail may serve as a service loop that allows a portion of a housing for the device and electrical components mounted to the central portion in alignment with windows in the housing to be detached for servicing.

    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.
