    Abstract: A printed circuit board with a microstrip radio frequency delay line deposited thereon. In addition, a plurality of delay line segments are deposited on the board in close proximity to one end of the delay line. To achieve an overall desired delay length, one of the delay line segments is selected and serially inserted in circuit with the delay line by populating a surface mount circuit element between terminals at the ends of the delay line and the selected delay line segment.

    Abstract: An object of this invention is to provide a circuit board low in manufacturing cost in which aimed circuit patterns having a circuit gap therebetween can be short-circuited substantially irrespective of the length of the circuit gap while being insulated from other circuit patterns which are laid in the circuit gap. In a circuit board on which a plurality of circuit patterns are arranged, a selected one of circuit patterns is cut to have a circuit gap where the selected circuit pattern is laid across the remaining circuit patterns, in such a manner that the circuit gap divides the selected circuit patterns into two parts, a conductor formed by cutting a wire to the length of the circuit gap bridges the circuit gap, to short-circuit the two parts thereby to complete the selected circuit pattern, the conductor being insulated from the remaining circuit patterns laid across the circuit gap.

    Abstract: An electrical conductor fashioned from an electrically conductive material such as copper has a body portion and a pair of laterally extending legs. The body portion and the legs cooperate to define a recess which is substantially filled with an insulating material. That insulating material has a surface recessed from the ends of the legs toward the body portion that, along with the surface of the printed circuit board defines a gap which is suitably sized to receive an epoxy adhesive for temporarily attaching the electrical conductor to the printed circuit board.

    Abstract: An electrical circuit is formed by a process which permits the electrical testing of portions of the circuit during the circuit forming process. One or more temporary crossover members are formed, which may interconnect certain circuit paths, while spanning and not contacting other paths eventually to be interconnected into the circuit. The temporary crossover members are preferably formed, along with any other crossover members and/or electrical components desired, on a carrier member and then transferred onto a dielectric substrate carrying the circuit paths. Electrical testing of the incomplete circuit follows. The circuit is thereafter completed with deformation of the temporary crossover members into electrical contact with the spanned circuit paths and bonding the deformed crossover portions to the spanned paths.

    Abstract: A layout without bridge taps includes: a routing from a CPU to a first module through a first set of pads; a routing from a first set of bridge pads to a second module through a second set of pads and a second set of bridge pads; a routing from a third set of pads to a third module; and connectors. The connectors connect pads of the first set of pads to couple the CPU with the first module, or connect the first set of pads with the first set of bridge pads and connect the second set of pads with the second set of bridge pads to couple the CPU with the second module, or connect the first set of pads with the first set of bridge pads and connect the second set of pads with the third set of pads to couple the CPU with the third module.
