    Abstract: A multilayer ceramic device suitable for use in surface mount decoupling applications may have a single capacitor or a capacitor array. The device has a capacitor body defining a plurality of electrical terminals on an outer surface thereof. The terminals are interdigitated such that a respective first polarity terminal will be adjacent to a respective second polarity terminal (and vice versa). The capacitor body contains a plurality of interleaved capacitor plates in opposed and spaced apart relation. Capacitor plates of the first polarity are electrically connected to respective first polarity terminals via a plurality of lead structures. Likewise, a plurality of lead structures electrically connect capacitor plates of the second polarity to respective second polarity terminals.

    Abstract: To facilitate a grounding connection between a circuit board and a chassis upon which it is to be mounted, a spaced series of unlined mounting holes are formed through the substrate portion of the circuit board between its top and bottom sides, and spaced series of grounding vias are formed through the substrate and positioned in a circular arrays around each of the mounting holes. Annular layers of a metallic plating material are formed on the opposite sides of the circuit board substrate, around the top and bottom ends of the unlined mounting holes, with the plating material being extended along the interior side surfaces of the vias between associated top and bottom annular plating material layers. Using solder masks placed on the opposite sides of the circuit board substrate, circular arrays of solder pads are formed on the outer side surfaces of the annular plating layers, with each solder pad array being interdigitated with the vias in one of the circular arrays thereof, and being horizontally offset from the vias. The bottom side of the circuit board is secured against a side of the chassis by extending metal mounting screws through the unlined mounting holes of the circuit board and threading the screws into corresponding holes in the chassis to press the bottom side solder pads of the circuit board against the chassis.
