Abstract
A soft-handling drop shuttle for use in an integrated circuit device handler. The invention includes a shuttle assembly (10) which pivots from a first position, in registration with an intake chute (36), and a second position, in registration with a discharge chute (50). The shuttle assembly (10) includes a shuttle lower jaw (14) for supporting an integrated circuit device (38) during its transfer, and a shuttle upper jaw (22), which is pivotally attached by an upper jaw pivot shaft (32) to the shuttle assembly (10). Upper jaw (22) retains the integrated circuit device (38) within the shuttle assembly (10) during the movement of the shuttle. The shuttle upper jaw (22) includes a stop portion (54) and an associated leaf spring (28) for retaining and clamping the integrated circuit device (38) within the shuttle assembly (10). Interchangeable shuttle lower jaws (14, 14') enable adaptation of assembly (10) to accommodate integrated circuit devices (38) of varying sizes and types.
