Familiar with die shear on die, but not for heatsinks. Although, it should still be meaningful if you had equipment that measured to that high a value. Die shear test methods: Mil-Std-883, Method 2019 Mil-Std-750, Method 2017 IPC-TM-650, Method 2.4.42.2 Mil test methods available at http://www.dscc.dla.mil/ IPC test methods available at http://www.ipc.org Test houses maybe close to you and possibly capable: ISE Labs, http://www.iselabs.com/ Brosnan Test Labs, http://www.brosnantest.com/ Microtek (Anahiem), http://www.thetestlab.com Pentest Reliability Services, http://www.pentest.com/ Sorry if I missed anyone in this geographic location, and if I did, please let me know.
