    Abstract: A ground plane interconnection is provided on first and second substrates, the first and second substrates having respective first and second ground layers disposed on a first surface of each of the first and second substrates. A ground conductor strip is disposed on a second surface of the second substrate, wherein the ground conductor strip includes a plurality of electrically conductive members which pass through the second substrate to electrically couple the ground conductor strip and the second ground layer. The first substrate is positioned with respect to the second substrate such that when the first substrate is placed proximate the second substrate, the ground conductor strip electrically couples the first and second ground layers to form a continuous ground plane. A method of forming a reduced-inductance continuous ground plane is also provided.

    Abstract: Disclosed herein is a display to be applied to a digital switch. This display includes a casing (1) formed of a box-type casing (2) and a cover (3), a display element (8) facing a display window (2b) accommodated in the casing (1), a printed wiring board (9) for supporting the display element (8), and a printed wiring board (14) which is connected to the printed wiring board (9) and on which a control circuit (16) for displaying an external input signal on the display element (8), and the like are mounted. At the front portion of the casing (1) is formed frames 11a and 11b extending over a display face (8) of the display element (8), and thus a portion of the printed wiring board (9) which is located at the outer periphery of the display element (8) cannot be seen from the outside. A conductive pattern (18) for discharging a static electricity is provided on the printed wiring board (9), corresponding to a region in which the frames (11a, 11b) engaged with each other. The frames (11a, 11b) have adhesive tapered faces, and thus a static electricity is hard to enter the display from the outside. Thus, it flows out of the display through the conductive pattern (18) even if it enters the display.

    Abstract: A paddle board for a connector for one or two ribbon cables having closely spaced signal and ground wires, includes on one or both major surfaces a plurality of wire-terminating pads comprising conductive material along bottoms of wire-receiving grooves proximate the cable-proximate edge of the board, the grooves defined by serrate ridges. Circuit paths extend from the signal ones of the wire-terminating pads to terminal-connecting pads along one or both major surfaces at a connector-proximate edge of the board to be connected to signal terminals of the connector. Other circuit paths extend from ground ones of the wire-terminating pads to a ground bus which includes at least one ground circuit path extending to a ground terminal-connecting pad along the connector-proximate edge. The wires of each ribbon cable are soldered to the wire-terminating pads after being wiped into the grooves, and the ridges serve as integral wire alignment means. The paddle board is molded of plastic and then plated to define the pads and circuit paths, and can include molded through-holes which become plated, and can also easily have a shape molded to include other structural features such as cable-receiving recesses as desired. A solder strip can be placed transversely across the row of wire ends and melted by a transverse hot bar, with interruptions in the ridges defining a strip- and bar-receiving region.

    Abstract: Various configurations of a grounding element or conductive element for a printed circuit board (PCB), as well as a process for manufacturing, are disclosed. For example, a PCB can include a solder grounding element connecting a copper track to a metal substrate, where the solder grounding element is applied via ultrasonic soldering during a manufacturing process. In another example, a PCB can include a spring pin grounding element connecting a copper track to a metal substrate. In yet another example, a PCB can include an auto splice grounding element connecting a copper track to a metal substrate. In yet another example, a PCB can include a press fit pin grounding element connecting a copper track to a metal substrate. In yet another example, a PCB can include a clip pin grounding element connecting a copper track to a metal substrate.
