    Abstract: A position transducer has an input shaft coupled to a variable inductance sensor to produce an output electrical signal representing shift angle position. The transducer includes a plurality of rigid circuit boards which are hinged to one another so that the circuit boards and the electronic circuitry supported on the boards can be wrapped around the variable inductance sensor. The individual rigid circuit board segments are laminated onto a flexible sheet having conductive tracks. The track sheet provides the hinged effect.The power supply which is mounted on one or more of the boards provides DC power through an AC circuit fed by a transistor which is switched on and off as a function of the power needs of the transducer. By thus having an ON duty cycle substantially less than 100 percent, the heat generated in the power supply is minimized thereby making feasible the packing density afforded by the plurality of hinged circuit boards.

    Abstract: A telephone connector in which a contact holder carrying a plurality of contacts is disposed in a body which has in its front a plug receiving hole and is open at its bottom. Mounting members for mounting the body on a printed circuit board are provided on both side panels of the body. The mounting members define the plane in which the body is mounted on the printed circuit board. Lower end faces of both side panels of the body are substantially flush with this plane. After terminals of the contacts have been automatically soldered to the printed circuit board, the open bottom of the body is closed by a separately prepared cover.

    Abstract: There is disclosed a scoring cutter for scoring printed circuit boards to a uniform thickness. The scoring cutter has top and bottom circular blades set to a gap and rotatable in opposite directions to each other. Resilient wheels, four in number, having diameters slightly larger than the blades, are mounted for rotation with respect to the blades, one on each side of each blade. A circuit board is fed between the blades, and the resilient wheels position the circuit board in the gap between the blades.

    Abstract: A singulation system wherein a multiplicity of circuit board members, or the like, can be fabricated by assembling components in a predetermined array on a large planar board-like member with portions of the large member defining independent circuit board assemblies which are separated from each other by intervening slots. The system includes readily adjustable punch and die plate members and accomodating platens which accomplish separation of the independent board assemblies from the large board arrangement without damage to the components mounted thereon.

The flexible circuit board has a plurality of conductive paths on each surface and a plurality of conductively plated-through apertures being connected to the conductive paths. One side of the flexible circuit board is adapted to carry components with leads; the other side of the flexible circuit board is adapted to receive components without leads. A carrier member, larger than the flexible circuit board and of a size and shape sufficient to accommodate the placement of at least one flexible circuit board, is also provided. The carrier member has a plurality of apertures which are in alignment with the apertures of the flexible circuit board, and a plurality of elongated slots in predetermined positions which extend the entire width of the flexible circuit board which is temporarily affixed onto the carrier member.

    Abstract: A relatively brittle sheet material, for example, a printed circuit board substrate, is subdivided into sections the boundaries of which are defined by apertures which permit the substrate to be fractured at the boundaries. Each aperture has side walls which intersect at points aligned along a separation line. Bending stresses are concentrated at the intersecting side walls to provide a clean straight fracture along the boundary.
