  • Patent number: 11195659
    Abstract: Improved termination features for multilayer electronic components are disclosed. Monolithic components are provided with plated terminations whereby the need for typical thick-film termination stripes is eliminated or greatly simplified. Such termination technology eliminates many typical termination problems and enables a higher number of terminations with finer pitch, which may be especially beneficial on smaller electronic components. The subject plated terminations are guided and anchored by exposed internal electrode tabs and additional anchor tab portions which may optionally extend to the cover layers of a multilayer component. Such anchor tabs may be positioned internally or externally relative to a chip structure to nucleate additional metallized plating material. External anchor tabs positioned on top and bottom sides of a monolithic structure can facilitate the formation of wrap-around plated terminations.

  • Patent number: 8446705
    Abstract: Disclosed are apparatus and methodology for inexpensive realization of one or more secondary capacitors within a monolithic body that already includes a first, larger capacitor to provide ultra wideband structures. Alternating layers of electrodes are provided with arm portions that embrace portions of adjacent electrode layers so as to create additional coupling effects within the capacitor structure thereby producing multiple additional equivalent capacitor structures within the device.

  • Patent number: 7889020
    Abstract: Disclosed is methodology and apparatus for producing an asymmetrical filter for use with implantable medical devices, and in other input filtering environments. Differing forward and reverse characteristic responses are provided by inserting a low value resistor in series with heart connecting leads so that EMI input protection may be provided without significantly reducing energy transfer from the protected device. Improved protection against voltage transients is provided with present arrangements of differentiated series impedance. Higher frequency energy is allowed out of a subject device than is allowed into such device, which allows for attenuation of undesired frequency ranges entering the filter while allowing output pulses to exit without distortion.

  • Publication number: 20100188799
    Abstract: Multilayer capacitors incorporate both low inductance (ESL) and controlled Equivalent Series Resistance (ESR) features into a cost-effective unitary device. Internal electrode patterns generally include one or more pairs of mother electrodes adapted for external connection (e.g., to a circuit, another electrical component, circuit board, or other mounting environment), and multiple pairs of daughter electrodes adapted only for internal connection to other electrodes (e.g., other daughter electrodes and/or selected mother electrodes) without direct connection to an external circuit. Mother and daughter electrodes are interdigitated with electrode tab features, where daughter electrodes have internal-connection tabs, and mother electrodes have both internal-connection tabs and circuit-connection tabs, all of which are connected to respective internal-connection or circuit-connection terminals.

  • Patent number: 7724496
    Abstract: The present subject matter is directed to methods and apparatus for providing a multilayer array component with interdigitated electrode layer portions configured to selectively provide signal filtering characteristics, over-voltage transient suppression capabilities, and land grid array (LGA) terminations. Embodiments of the present subject matter may define a single capacitor, a capacitor array, or a multilayer vertically integrated array with configurable equivalent electrical characteristics including equivalent series inductance (ESL), equivalent series resistance (ESR), and configurable capacitance and voltage clamping and transient suppression capabilities.

  • Patent number: 7697262
    Abstract: Low inductance capacitors include electrodes that are arranged among dielectric layers and oriented such that the electrodes are substantially perpendicular to a mounting surface. Vertical electrodes are exposed along a device periphery to determine where termination lands are formed, defining a narrow and controlled spacing between the lands that is intended to reduce the current loop area, thus reducing the component inductance. Further reduction in current loop area and thus component equivalent series inductance (ESL) may be provided by interdigitated terminations. Terminations may be formed by various electroless plating techniques, and may be directly soldered to circuit board pads. Terminations may also be located on “ends” of the capacitors to enable electrical testing or to control solder fillet size and shape. Two-terminal devices may be formed as well as devices with multiple terminations on a given bottom (mounting) surface of the device.

  • Patent number: 7576968
    Abstract: A multilayer electronic component includes a plurality of dielectric layers interleaved with a plurality of internal electrodes. Internal and/or external anchor tabs may also be selectively interleaved with the dielectric layers. Portions of the internal electrodes and anchor tabs are exposed along the periphery of the electronic component in respective groups. Each exposed portion is within a predetermined distance from other exposed portions in a given group such that termination structures may be formed by deposition and controlled bridging of a thin-film plated material among selected of the exposed internal conductive elements. Electrolytic plating may be employed in conjunction with optional cleaning and annealing steps to form directly plated portions of copper, nickel or other conductive material. Once an initial thin-film metal is directly plated to a component periphery, additional portions of different materials may be plated thereon.

  • Patent number: 7573698
    Abstract: A method of forming a window via capacitor comprises a first step of providing a plurality of interleaved dielectric layers and paired electrode layers to create a multilayered arrangement characterized by top and bottom surfaces and a plurality pf side surfaces. First and second transition layer electrode portions are provided on a top surface of the multilayered arrangement on top of which a cover layer formed to define openings, or windows, therein is provided. The cover layer may be provided before device firing or may be printed on after firing using polymer or glass. Peripheral terminations are subsequently formed on the device periphery to connect selected electrode layers to respective transition layer electrode portions. Via terminations are formed in the cover layer openings, on top of which solder balls may be applied. Some of the terminations may be formed in accordance with various plating techniques as disclosed.

  • Publication number: 20090147440
    Abstract: Methodologies and structures are disclosed for providing multilayer electronic devices having low inductance and high ratings, such as for capacitor devices for uses involving faster pulsing and higher currents. Plural layer devices are constructed for relatively lowered inductance by relatively altering typical orientation of capacitors such that their electrodes are placed into a vertical position relative to an associated circuit board. Optionally, individual leads may be formed so that the resulting structure can be used as an array. Internal electrodes may be arranged for reducing current loops for associated circuits on a circuit board, to correspondingly reduce the associated inductance of the circuit board mounted device. Leads associated with such devices may have added tab-like structures which serve to more precisely place the lead, to improve the lead to capacitor strength, and to promote lower resistance and inductance.
