Heatsink Clip Load Methodology Alternate Heatsink Sample Preparation As just mentioned, making sure that the load cells have minimum protrusion out of the heatsink base is paramount to meaningful results. An alternate method to make sure that the test setup will measure loads representative of the non-modified design is: • Machine the pocket in the heatsink base to a depth such that the tips of the load cells are just flush with the heatsink base. • Then machine back the heatsink base by around 0.25 mm [0.01"], so that the load cell tips protrude beyond the base. Proceeding this way, the original stack height of the heatsink assembly should be preserved. This should not affect the stiffness of the heatsink significantly. Figure C-1.
