    Abstract: A system includes a circuit board, an inductor including windings mounted on the circuit board, and a plurality of magnetic field containment devices. Each magnetic field containment device includes an independent electrical circuit that is not directly electrically connected via a conductor to any other magnetic field containment device. Each magnetic field containment device also includes a material of a certain relative permeability. Each magnetic field containment device at least partially surrounds the inductor and, in operation, at least partially contains a magnetic B-Field generated by electrical current in the windings of the inductor. The plurality of magnetic field containment devices, in operation, enables a certain saturation current in the inductor.

    Abstract: An electronic device may include surface mount technology components mounted to a printed circuit board. The surface mount technology components may include electrical components such as resistors, inductors, and capacitors. In order to reduce the size of the electronic device, surface mount technology components may be stacked. A surface mount technology component may be mounted to metal members that electrically connect the surface mount technology component to contact pads on a printed circuit board. A surface mount technology component may be provided with integral standoff portions, and a second surface mount technology component may be mounted to the integral standoff portions. A single surface mount technology component may be used to implement different circuits depending on which face of the surface mount technology component is mounted to the printed circuit board.

    Abstract: Monolithic capacitor structures having a main capacitor and a vise capacitor are discussed. The vise capacitor provides to the monolithic capacitor structure reduced vibrations and/or acoustic noise due to piezoelectric effects. To that end, vise capacitor may cause piezoelectric deformations that compensate the deformations that are caused by the electrical signals in the main capacitor. Embodiments of these capacitor structures may have the main capacitor and the vise capacitor sharing portions of a rigid dielectric. Electrical circuitry that employs the vise capacitor to reduce noise and/or vibration in the monolithic capacitor structures is also described. Methods for fabrication of these capacitors are discussed as well.

    Abstract: Methods and devices related to the design and fabrication of molded cores for printed circuit board assemblies and system-on-package (SIP) devices are discussed. The discussed printed circuit board assemblies may have multiple electrical components embedded in a molded core matrix and forming electrical connections with one or more printed circuit boards attached to the molded core matrix. Methods for sourcing of electrical components and production of the molded cores and printed circuit board assemblies are also discussed. The methods and devices may increase a volumetric density of electrical components in printed circuit board assemblies and provide improved mechanical properties to the electrical circuit device.
