Abstract: A method and related fixtures are disclosed which permit formation of stacks of thin circuitry-carrying layers. The layers terminate in an access plane having a two dimensional array of closely-spaced electrical leads. The method includes the steps of measuring the thickness of separate chips, selecting groups of chips having appropriate thicknesses, applying appropriate amounts of epoxy between adjacent chips, aligning the chips (and their electrical leads) in the direction parallel to their planes (i.e., the X-axis), and closing the cavity with an end wall which (a) exerts pressure on the stacked chips and epoxy in a direction perpendicular to the chip planes, and (b) establishes a fixed height of the stack in order to align the leads in the Y-axis. The final fixture provides a fixed-size cavity for confining the layers during curing of thermo-setting adhesive which has been applied between each adjacent pair of layers.

Abstract: A self-alignable holder holds a row of coupling elements mounted on a slide fastener stringer tape in alignment with a slot cutter regardless of the size of the coupling elements. The holder includes a base having a slot receptive of the stringer tape, a pair of parallel holding plates movably disposed on the base for laterally sandwiching the row of coupling elements therebetween, a pair of parallel-motion links pivotally connecting the holding plates together, and a pair of supports mounted on the base and pivotally supporting the links so that the gripping edges of the holding plates are equidistant from the longitudinal axis of the slot. Spring means in the base urge the holding plates laterally toward each other for holding the row of coupling elements in longitudinal alignment with the slot axis resiliently with equalized lateral forces.

Abstract: A flat rectangular workpiece, such as a photographic plate in a photo-repeating apparatus designed to produce integrated-circuit masks, laterally overhangs a platform of a carriage which is slidable on a mobile supporting table. The platform has two end stops and a side stop defining the relative position of the workpiece thereon, the overhanging edges of the workpiece entering between upper and lower jaws of three grippers -- one on one side and two on the other -- when the carriage is slid into a working position. The lower gripper jaws, constituted by spring-loaded plungers normally held down by suction, are then released to lift the workpiece off the platform while clamping it against the overlying upper jaws.
