    Abstract: Multilayer ceramic capacitor structures may include structural arrangements, materials, and/or substrate modifications that can improve the reliability of the capacitor for long-term usage when faced with environmental stress. Embodiments may implement reduced entryways in the termination patterns of the capacitor to decrease damage potential due to exposure of moisture. Embodiments may implement structures that decrease interfaces with different physical characteristics, which may lead to a reduction in the formation of micro-fractures during regular usage. Methods of manufacture for the features that improve reliability are also detailed.

    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: 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.
