A magazine into which a plurality of fixtures holding integrated circuit chips can be inserted serially by a machine and from which the fixtures can be removed serially by a machine. The fixtures are loaded through an opening in the bottom of the magazine and are removed from the magazine through the same opening. The magazine provides protection to the fixtures and chips held by the fixtures during storage and handling encountered in the typical manufacturing environment for electronic systems. The magazine facilitates automating the processes of accumulating fixtures holding integrated circuits of a given type and of assembling in one magazine the desired number of fixtures holding integrated circuit chips of the appropriate types preparatory to mounting the chips on a multilayer substrate.

A magazine for a plurality of fixtures, each fixture being adapted to hold a segment of a film strip having a lead frame attached to the segment and an integrated circuit chip bonded to the lead frame, the outer surfaces of each fixture substantially defining congruent rectangular parallelipipeds, the distance between the top and bottom faces of said parallelipipeds being the height of the fixtures and the top faces of the parallelipipeds being rectangular, said magazine comprising: a hollow tube having a front wall, a back wall and a pair of side walls, each of said walls having a substantially planar inner face, each wall having a length and a width; a pair of ribs formed on the inner faces of each wall of the tube, said ribs being substantially parallel to the intersections of the inner faces of the walls of the tube, said ribs being spaced apart and the cross section of the ribs being substantially a segment of a circle; the cross sectional area of the space defined by planes substantially tangent to the surfaces of the ribs being slightly greater than the area of the top face of a fixture so that a fixture loosely fits within said space; a pair of rails having substantially planar and parallel upper and lower faces; the width of each rail being substantially less than one half of the width of the front wall and the length of each rail being greater than the length of a side wall; each of said rails having a front end and a back end; one of said rails being fixedly secured to one side wall and a portion of the back wall and the other of said rails being fixedly secured to the other side wall and another portion of the back wall so that the rails are substantially parallel to each other, so that they are uniformly spaced from each other, so that the back end of each rail projects beyond the back wall to form a pair of back ledges, and so that the front end of each rail extends beyond the inner surface of the front wall; means forming an opening in the front wall, the minimum height of the opening measured from the upper faces of the rails being greater than the height of a fixture, the maximum height of the opening being less than twice the height of a fixture, and the width of the opening being substantially the complete width of the front wall; means forming an opening in the back wall, the minimum height of the opening measured from the upper faces of the rails being at least a substantial portion of the height of a fixture and its width being substantially equal to the distance between the rails; the front portion of the rails having means forming a step, the projecting portion of the step constituting front ledges; and means forming a key slot in one of the front ledges.
