Mechanical Characteristics and Ratings

Figure 9. Flatness Measurement Position

Figure 10. Mounting Screws Torque Order

Note:

12. Do not make over torque when mounting screws. Much mounting torque may cause ceramic cracks, as well as bolts and Al heat-sink destruction.

13. Avoid one-sided tightening stress. Figure 10 shows the recommended torque order for mounting screws. Uneven mounting can cause the ceramic substrate of package to be

damaged. The pre-screwing torque is set to 20 ~ 30% of maximum torque rating.
