  • Publication number: 20140218841
    Abstract: The described embodiments relate generally to a capacitor assembly for mounting on a printed circuit board (PCB) and more specifically to designs for mechanically isolating the capacitor assembly from the PCB to reduce an acoustic noise produced when the capacitor imparts a piezoelectric force on the PCB. Termination elements in the capacitor assembly, including a porous conductive layer in the capacitor assembly may reduce an amount of vibrational energy transferred from the capacitor to the PCB. Termination elements including a soft contact layer may also reduce the amount of vibrational energy transferred to the PCB. Further, capacitor assemblies having thickened dielectric material may reduce the amount of vibrational energy transferred to the PCB.

  • Patent number: 8749949
    Abstract: In a structure or device having a pair of electrical conductors separated by an insulator across which a voltage is placed, resistive layers are formed around the conductors to force the electric potential within the insulator to distribute more uniformly so as to decrease or eliminate electric field enhancement at the conductor edges. This is done by utilizing the properties of resistive layers to allow the voltage on the electrode to diffuse outwards, reducing the field stress at the conductor edge. Preferably, the resistive layer has a tapered resistivity, with a lower resistivity adjacent to the conductor and a higher resistivity away from the conductor. Generally, a resistive path across the insulator is provided, preferably by providing a resistive region in the bulk of the insulator, with the resistive layer extending over the resistive region.

    Abstract: A capacitor includes a dielectric substrate and a large number of filamentous conductors formed to penetrate through the dielectric substrate in a thickness direction thereof. An electrode is connected to only respective one ends of a plurality of filamentous conductors constituting one of groups each composed of a plurality of filamentous conductors. The electrode is disposed in at least one position on each of both surfaces of the dielectric substrate, or in at least two positions on one of the surfaces. Further, an insulating layer is formed on each of both surfaces of the dielectric substrate so as to cover regions between the electrodes, and a conductor layer is formed on the corresponding insulating layer integrally with a desired number of electrodes.

  • Patent number: 8638567
    Abstract: Manufacturing circuits with reference plane voids over vias with a strip segment interconnect permits routing critical signal paths over vias, while increasing via insertion capacitance only slightly. The transmission line reference plane defines voids above (or below) signal-bearing plated-through holes (PTHs) that pass through a rigid substrate core, so that the signals are not degraded by an impedance mismatch that would otherwise be caused by shunt capacitance from the top (or bottom) of the signal-bearing PTHs to the transmission line reference plane. In order to provide increased routing density, signal paths are routed over the voids, but disruption of the signal paths by the voids is prevented by including a conductive strip through the voids that reduces the coupling to the signal-bearing PTHs and maintains the impedance of the signal path conductor.

  • Patent number: 8614875
    Abstract: An anchor group anchors organic dielectric compounds used in the production of organically based capacitors. The capacitors referred to are those that can be produced in a parallel process on a prepeg or other common printed circuit board substrate without additional metallization on copper. The pre-fabricated capacitor layer can then be built into the printed circuit board, thereby gaining on space and cost for the surface of the printed circuit board.

  • Publication number: 20130335882
    Abstract: The invention is directed to a process for making a dielectric ceramic film capacitor and the ceramic dielectric laminated capacitor formed therefrom, the dielectric ceramic film capacitors having increased dielectric breakdown strength. The invention increases breakdown strength by embedding a conductive oxide layer between electrode layers within the dielectric layer of the capacitors. The conductive oxide layer redistributes and dissipates charge, thus mitigating charge concentration and micro fractures formed within the dielectric by electric fields.
