3. Through hole design for PCB
This chapter describes the through hole design for PCB attaching to the product (Small IPM).
3-1
Figures 3-1 to 3-4 show examples of recommended through hole dimensions and through hole layout
designs.
•The through hole dimensions are the inner diameter after plating (dimension unit: mm).
•If the terminal cross-sectional dimensions / through hole clearance is too large, solderability may be
impaired. Also, if the land diameter is too large, solder bridges are likely to occur.
•The hole size and land size should be optimized as appropriate, taking into consideration the printed
circuit board processing accuracy and mounting method.

5. Application of thermal grease
This chapter describes the thermal grease application for the product (Small IPM).
5-1
•It is recommended to apply thermal grease between the product’s aluminum base and the heat sink
to ensure heat dissipation to the heat sink. If the properties, amount, and application method of the
thermal grease are not appropriate, it may result in poor heat dissipation and lead to thermal failure.
Table 5-1 shows the recommended thermal grease properties and thickness
•Assuming that the thickness is uniform, the required amount (weight) of thermal grease can be
calculated from the following formula.
•We recommend using the stencil mask method to control the appropriate thermal grease thickness
(Fig. 5-1). The recommended stencil mask pattern is shown in appendix.
•It is recommended to check the spread of thermal grease by removing the product after mounting
and check the extent of spreading.
•In the case of liquid cooling, the temperature difference (temperature gradient) between the heat
sink temperature and the temperature inside the product becomes large. When mounting the
product to heat sink, secure a thermal grease coating amount that can absorb the distortion due to
the difference in thermal expansion when the temperature gradient is large.
•In the case of a multiple structure heat sink, the number of fastening parts increases and heat
transfer (diffusion) becomes uneven. Therefore, it is necessary to suppress the distortion, such as
securing the thermal grease coating amount in consideration of the generated distortion during
design.

6. Heat sink selection
This chapter describes the heat sink selection for the product (Small IPM).
6-1
•The junction temperature Tvj should not exceed the maximum junction temperature rating for safe
operation. Heat sink (cooling device) should be designed to ensures that Tvj is always below the
maximum junction temperature rating.
•If the IGBT or FWD junction temperature is higher than the maximum junction temperature rating, it
might cause damage to the chips. Some types of the products have the over heating (OH)
protection function which works when the LVIC chip temperature exceeds the maximum junction
temperature rating. However, if the temperature rises too quickly, the OH protection might not work.
•When selecting a heat sink, please verify the chip temperature Tvj by measuring Tcat the position
shown in Figure 6-1, and calculating the Tvj from device power dissipation and thermal resistance.
In addition, this product has a built-in temperature sensor, and Tvj can be confirmed by the analog
voltage that is output according to the LVIC chip temperature. Please refer to it when selecting the
heat sink.
•For more detail design, please refer to “IGBT Module Application Manual (REH984e)” and “Small
IPM Application Manual (MT6M12343)”.

•As shown in Fig. 6-2, the heat sink flatness should be 0μm/100mm to +100μm/100mm, and the
surface roughness (Rz) should be less than 10μm.
•If the heat sink surface is concave, a gap occurs between the heat sink and the product, leading to
deterioration of cooling efficiency.
•If the flatness is +100μm/100mm or more, the aluminum base of the product is deformed and cracks
could occur in the internal isolating substrates.
