AM6526: PET and Push pins Heatsink

Hideaki Matsumoto

Part Number: AM6526

Hi,

Could I have a Power Estimation Tools of AM65x ?

The customer is thinking about using a heat sink pressed by push pins and springs. Could you tell them how much pressing load can a package withstand ?

Regards,

Hideaki-san,

The AM6526 SoC which is 784 balls w/ 0.8mm pitch, can sustain a uniform pressure of ~6 lb across the top of the package. If the pressure is not uniform, then the absolute worst case pressure on any single bga ball must not exceed 33 grams.

Kyle

Hi Kyle,

Thanks so much for your answer. Let me confirm a little more. Does 6 lb mean 6 lbf/in2 (pound-force per square inch) ?

No, it's total uniform force over the area of the package.
