    Abstract: A stacked packaging assembly for a plurality of integrated circuit devices employs a web of flexible interconnect material folded into a `layered` arrangement of parallel web fingers onto which a plurality of integrated circuit devices are surface-mounted. The leads of the integrated circuit devices are attached to interconnect links of the flexible interconnect web. A plurality of heat sink plates are interleaved with the folded web fingers of the stack, so as to engage the integrated circuit devices mounted on the web fingers. The heat sink plates are retained by thermally conductive spacer blocks along their edges. The spacer blocks are clamped together in a compact laminate structure, so as to form a rigid support which relieves mechanical stresses at the folds of the web fingers.

    Abstract: A printed circuit board handle is disclosed for use with a printed circuit board. The printed circuit board handle includes a flange that extends for the length of the handle and is mounted to the printed circuit board. Two ribs protrude from the side of the flange that is adjacent to the printed circuit board and extend for the length of the handle. The ribs contact the printed circuit board in such a manner as to separate the body of the flange from the printed circuit board and thereby prevent the capillary action that causes entrapment of flux between the flange and the printed circuit board, during the wave soldering process.

    Abstract: A previously fabricated flat flexible cable (10) includes tears and/or micro-fissures, micro-cuts or other defects or imperfections, depicted by jagged or wavy lines (16), in its edges (18). A multi-fiber tread (20), placed at the cable's edges, is enclosed within, between and/or atop one or more layers of adhesive film (22). A bond material (26) bonds the film layers to themselves at their ends (28), to the cable respectively at its sides (24), and to the thread. The bond material is also bonded to and within the micro-fissures, micro-cuts or other defects for repair thereof. The bond material also bonds thread (20) to portions of the cable adjacent to the tear to prevent further propagation of the tear into the cable.

    Abstract: A stiffener for a printed circuit board which comprises an elongated metallic electrically conductive bar. Extending from the bar are a plurality of spaced apart pins with these pins being in longitudinal alignment. Each pin is constructed to facilitate physical deformation such as by including a through opening within the body of the pin or with the pin including notched-out areas in the side walls of the pin. Upon the pin incurring a sufficiently powerful striking force, the pin will deform and expand laterally.

    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.
