2nd Notes:
Figure 10. Mounting Screws Torque Order
10. Do not make over torque when mounting screws. Much mounting torque may cause ceramic cracks, as well as bolts and Al heat-sink destruction.
11. Avoid one side tightening stress. Figure 10 shows the recommended torque order for mounting screws. Uneven mounting can cause the ceramic substrate of the SPM^® 45
package to be damaged. The pre-screwing torque is set to 20 ~ 30% of maximum torque rating.
