Heat Spreader Implementation

Question asked by Matthew Ware on Apr 19, 2016

The Datasheet for MPC8640D says that "In any implementation of a heat sink solution, the force on the die should not exceed to pounds force".

 

1. If say an additional 10% of force, or a total of 11lbs force, would the die be at a high risk of damage?

2. Is that limit a constant clamping force, or a one lime installation force limit?

3. What would the main failure mode be if excessive force was applied? (fail at High current, immediate failure, failure at temperature. etc.)

 

Thanks!
