A lever-returning device is used as a centering mechanism for locating various sized multi-chip module (MCM) product heatsinks and acts as a clamp to secure the heatsink for processing. Fig. 1 is a partial drawing of the lever-returning assembly showing the top lever assembly 1 (or parallelogram) in the open position with clamps 2 and an MCM 3 in the center. Fig. 2 shows both the top lever assembly 1 and the bottom lever assembly 4 in the closed position with clamps 2 securing the MCM 3. The top lever assembly 1 and bottom lever assembly 4 are held together by means of top and bottom plates 5 that attach to each other by screws 6. The lever assemblies 1 and 4 are held in operating position by pivoting pins 7, 8, 9 and 10. Spacers (not shown) separate the plates 5 to provide room for lever assemblies 1 and 4.
