The IPC-A-610 went to the extent of defining heatsink acceptability
requirements such that "hardware meets mounting torque requirements if
specified."

Due to past problems, we are going to verify heatsinks withstand a certain
amount of torque.  Does anyone know of a recommended/benchmark torque
heatsinks should be able to withstand?

Our particular heatsink is about 1" x 1", .25" tall.  We have been using
Loctite 383.
