2-3. Screw fastening to heat sink
This section describes how to tighten the screws when mounting the module to heat sink.
1.
Use M5 screws to fix the module to heat sink.
2.
To fix the module with even force, first perform temporary tightening with 1/3 of the final
tightening torque. Figure 3 shows the tightening sequence.
3.
Perform final tightening in the same sequence as temporary tightening. The final tightening
torque should be within the range of 2.5~3.5Nm.
