ABSTRACT:
Apparatus (10) for centering an integrated circuit device (12) along X and Y axes (95, 97) with respect to a Z axis (39). First and second jaw pairs (98, 100), are actuated so that corresponding jaws of each pair are, at all times, disposed along their respective axis at equal distances from the Z axis (39). Corresponding jaws of each pair (98, 100) are, concurrently, moved toward and away from the Z axis, therefore. In a preferred embodiment, actuation is effected by means of linear extender rods, (70, 72) which, in turn, in effect rotation of discs (26, 28) and their corresponding turnstiles (106, 114). Turnstile (106, 114) rotation, in turn, effects linear movement of track riders (84, 86) to which the jaw pairs, (98, 100) are mounted.
