Laboratory tests on a limited number of samples indicate, when using the screw and compression washer mounting technique, a screw torque of 6 to 8 in
.
lbs is sufficient to provide
maximum power dissipation capability. The compression washer helps to maintain a constant pressure on the package over time and during large temperature excursions.
Destructive laboratory tests show that using a hex head 4–40 screw, without washers, and applying a torque in excess of 20 in
.
lbs will cause the plastic to crack around the mounting
hole, resulting in a loss of isolation capability.
Additional tests on slotted 4–40 screws indicate that the screw slot fails between 15 to 20 in
.
lbs without adversely affecting the package. However, in order to positively ensure
the package integrity of the fully isolated device, Motorola does not recommend exceeding 10 in
.
lbs of mounting torque under any mounting conditions.
