TAS5624A: Heatsink mounting recommendation : Maximum torque force that IC can sustain

Part Number: TAS5624A

My customer facing some market feedback due to D-amp IC broken.

This D-amp IC broken caused by mechanical heatsink vibration which make some IC pin break.

Customer would like to understand how much kg/f can stand for screw torque or maximum load (kg) withstand when the heatsink mounted on top of the IC.

Customer wants to study to improve vibration to avoid broken pin IC with strengthen the screw torque of the heatsink.

Please provide heatsink mounting data(screw torque) /recommendation for HTSSOP or similar IC package.


Best regards,
