Abstract

Integrated circuit chips are carried in the individual pockets of a magazine that is mountable on an automatic indexing mechanism for loading and unloading operations. Magazine 1 is formed of plural disc layers 2, 3, 4. Disc 3 has a thickness slightly greater than that of the thickness of a chip and is provided with a plurality of individual chip pockets 5, identified by serial numbers 14, 16, 18, along a circular path near its outer periphery. Chips 6 fit into each of the pockets. Each of the discs 2, 3, 4 is mounted for pivotable movement around a common hub 7, such that any disc can be individually rotated around this axis.

Integrated Circuit Chip Magazine

Integrated circuit chips are carried in the individual pockets of a magazine that is mountable on an automatic indexing mechanism for loading and unloading operations. Magazine 1 is formed of plural disc layers 2, 3, 4. Disc 3 has a thickness slightly greater than that of the thickness of a chip and is provided with a plurality of individual chip pockets 5, identified by serial numbers 14, 16, 18, along a circular path near its outer periphery. Chips 6 fit into each of the pockets. Each of the discs 2, 3, 4 is mounted for pivotable movement around a common hub 7, such that any disc can be individually rotated around this axis.

Outer discs 2 and 4 are identical parts made of a transparent material and each of these has a window 8 having a size slightly larger than the size of pocket
5. Through this window, chip 6 is insertable into or removed from a pocket. Latch and pocket closure assembly 9 is provided, which is movable in a radial direction in each of the outer discs 2 and 4 to permit or prevent access through a window to a chip. Through window 8, one chip at a time is exposed from either direction for a desired operation. In rotating, outer discs 2 and 4 are controlled in movement by a ratchet arrangement 10 so that the window is always seated above a pocket. When magazine 1 is mounted on an automatic indexing mechanism for loading or unloading of chips, operations such as sorting, visual inspection and chip placement are perfo...
