1. Soldering to PCB
•The product’s temperature during soldering might exceed the maximum storage temperature.To
prevent damage to the product and to ensure reliability, please use the following soldering
temperature.
Table 6.1 Soldering temperature and duration
• A stopper is provided on the terminal to prevent the immersion depth of the terminal from coming
too close to the product body.Use this stopper to secure the required distance from the printed
circuit board and prevent the product body from being immersed in the solder bath during flow
soldering.
•It is not recommended to reuse the product after it is removed from the printed circuit board
because there is apossibility that the removed product was subjected to thermal or mechanical
damage during the removal process.
2. Mounting to Heat Sink
•When mounting the product to aheat sink, please refer to the following recommended fastening
order.Uneven fastening due to excessive torque might lead to destruction or degradation of the
chip.
Fig.6-1 Recommended screw fastening procedure
1 2
Note) The pre-screwing torque is set to 30% of the final screwing torque rating(0.59～0.98N･m)
•Fig.6-2 shows the measurement position of heat sink flatness.
•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, agap occurs between the heat sink and the product, leading to
deterioration of cooling efficiency.
•If the flatness is +100µm/100 mm or more, the aluminum base of the product is deformed and
cracks could occur in the internal isolating substrates.

In order to achieve good heat dissipation, thermal grease with high thermal conductivity should be
applied evenly to the contact surface between the product and the heat sink.The stencil mask method
(Fig. 6-3) is recommended to control the appropriate thermal grease thickness.Please refer to
mounting instruction for the recommended characteristics, amount, stencil mask pattern, etc.of
thermal grease.

3. Heat Sink Selection
•Please make sure that the junction temperature Tvj should not exceed the maximum junction
temperature rating for safe operation. Heat sink should be designed to ensures that Tvj is always
below the maximum junction temperature rating even during abnormal conditions such as overload
operation as well as during rated load.
•Operating the IGBT above the maximum junction temperature rating can cause damage to the chips.
The over heating (OH) protection function works when the IGBT junction temperature exceeds the
maximum junction temperature rating. However, if the temperature rises too quickly, the OH
protection might not work.
•Please note that the junction temperature of FWD should not exceed the maximum junction
temperature rating too.
•When selecting a heat sink, please verify the chip temperature by measuring at the position shown
in Fig.2-2.
