Recommended isolated mounting when
screw is at heatsink potential. 4-40
hardware is used.
Screw should not be tightened with any
type of air-forced torque or equipment
that may cause high impact on device
package. The insulating bushing inside
the mounting hole will insure the screw
threads do not contact the metal base.
The interface should apply a layer of
thermal grease or a highly conductive
thermal pad for better heat dissipation.
