Abstract:
An inversion handler for inverting an integrated circuit (â€œICâ€ ) device under test (â€œDUTâ€ ), the inversion handler comprising:a stationary finger; a movable finger coupled to the stationary finger, wherein the movable finger is adapted to be moved to releasably secure the IC DUT between the stationary finger and the movable finger; an arm coupled to the stationary finger; a shaft coupled to the arm; a driving device coupled to the shaft, to rotate the shaft approximately one-hundred eighty degrees, wherein such rotation will rotate the stationary finger and the movable finger in a vertical plane which is perpendicular to the axis of the shaft, such that the stationary finger and the movable finger are inverted; and a precising pin coupled to the stationary finger, for engaging with a carrier which is designed to carry the IC DUT.
