is provided in Figure 6-1.

(Note 1) Plain washers of 8mm outside diameter (ISO 7089 to 7094) are recommended.

(Note 2) When installing a module to a heat sink, excessive uneven fastening force might apply stress to inside chips or ceramic of heat sink plate, which will

break or crack or degrade a module. An example of recommended fastening sequence is shown in Figure 5. The temporary fastening torque is set to

20 to 30% of the maximum torque rating. Evenly apply thermally-conductive grease with 100µm to 200µm thickness over the contact surface

between the module and the heat sink. Also, pay attention not to have any dirt left on the contact surface between the module and the heat sink.

It is recommended to install a module directly to a heat sink after applying grease. When installing a module to a heat sink, inserting a heat radiation

sheet between a module and a heat sink might apply stress depending on thickness and elastic modulus of the sheet to inside chips or ceramic of

heat sink plate, which will break or crack or degrade a module. When using a heat radiation sheet, it is needed to prevent IPM from bending into +

side of Figure 6-2.
