    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: An electronic device may be provided with integrated circuits and electrical components such as capacitors that are soldered to printed circuit boards. Liquid polymer adhesive such as encapsulant and underfill materials may be deposited on the printed circuit. Electrical components such as capacitors may be coated with the encapsulant. The underfill may be deposited adjacent to an integrated circuit, so that the underfill wicks into a gap between the integrated circuit and the printed circuit board. The encapsulant may be more viscous than the underfill and may therefore prevent the flowing underfill from reaching the electrical components. Some of the encapsulant may be located between the electrical components and the printed circuit board. The encapsulant can be cured to form an elastomeric material covering the electrical components that helps damp vibrations. The elastomeric material may be less stiff than the underfill.

    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.
