This chapter describes the precautions in unpacking for the product
2. Precautions in unpacking
- Removing the pin from the tube
• The products are packaged in tubes that are pinned at both ends
• Remove the pin on one side to pick out the product from the tube
• If the pin and the product are in contact with each other when removing the pin, a strong impact
might be applied to the product, which may cause deformation or damage to the product terminals
Make a gap between the pin and the product when removing the pin
• The recoil of removing the pins may cause deformation or damage to the terminals of the product,
so remove the pins while holding them
• If the product falls out from the tube when removing the pins, it may cause a strong impact to the
product, causing the product terminals to be deformed or damaged Remove the pin with the tube
opening facing up
• It is recommended to use a remover (removal jig) to remove the pins The following shows how to
remove the pins using a remover
A) Make a gap between the pin and the product ..(See Fig 2 1)
Fig. 2 1 Gap between the pin and the product
B) Push the pointed end of the pin with your index finger, and make a gap
between the pin and the
tube to insert the remover removal part as shown in Fig 2 2 ..(See Fig 2 3
C) Insert the removal part of the remover into the gap between the pin and the tube. (See Fig. 2 4)
D) Hold the pin with your finger and remove the pin with the tube opening
facing up.
( See Fig. 2 5, 2 6)
2. Removing the product from the tube
• Since the elements installed in the Small IPM are extremely weak to
electrostatic discharge,
appropriate ESD countermeasures are necessary in the assembly environment
within the range
described in the specifications In particular, when removing it out from the
tube, it is most likely to
cause electrical damage to the product
• When removing the product, do not strongly collide the products with each
other or bump the
product terminals against the tube A strong impact on the product may cause
deforming or damage
to the product terminals
This chapter describes the Through hole design for PCB attaching to the product.
3. Through hole design for PCB
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.
This chapter describes the spacer for PCB attaching to the product
4. Spacer
• When using spacer between the PCB and the product for alignment during
soldering to printed
circuit board, it is recommended to support the product at the hatched area as
shown in Fig 4 1
• Select a spacer material that does not cause contamination or corrosion
5. Application of thermal grease
• 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 is 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 ( 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 ( 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
1. Selection
-
The junction temperature T vj should not exceed the maximum junction temperature rating for safe
operation Heat sink (cooling device) should be designed to ensures that T vj 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 overheating ( 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 T vj by measuring T c at the position
shown in Figure 6 1 and calculating the T vj from device power dissipation and thermal resistance
In addition, this product has a built in temperature sensor, and T vj can be confirmed by the analog
voltage that is output according to the LVIC chip temperature Please use this as a reference when
selecting a heat sink -
For more detailed design, please refer to IGBT Module Application Manual (REH 984 and Small
IPM Application Manual
･ P 633 A Application Manual MT 6 M 08855
･ P 633 C Application Manual MT 6 M 16945
2. Shape
• 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
may deform and
cracks could occur in the internal isolating substrates.
3. Mounting (tightening)
• When mounting the product to a heat sink, the following fastening order is
recommended. Uneven
fastening due to excessive torque might lead to destruction or degradation of
the chip.
• Standard: Metric screw JIS B 1111
• Screw length: 8mm
• Screw head shape: Pan shape (head diameter 5.5 mm)
• Material: Stainless
• Use flat washers (JIS B1258 recommended). Washer head type screws can be
used as well.
• Avoid using the product to support the load of structure such as heat sink,
printed circuit board, etc.
• When mounting this product together with other components to the heat sink,
ensure the flatness of
the components mounted on the printed circuit board before mounting.
7. Soldering to Printed Circuit Board
• The product’s temperature during soldering might exceed the maximum
temperature rating To
prevent damage to the product and to ensure reliability, please use the
following soldering
temperature

• 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 a possibility that the removed product was subjected to
thermal or mechanical
damage during the removal process

if you need a dxf file.
2. Isolation distance of heat sink
• When this product is mounted on a flat heat sink, there is a possibility
that discharge will occur
between the lead terminals and the heat sink, so the isolation voltage is 1.5
kVrms.
• By ensuring a creepage distance of 2.5 mm or more between the lead terminals
and the heat sink,
the isolation voltage will be 2.5 kVrms.
• By processing the heat sink as shown in Fig. 8-2, it is possible to secure a
clearance distance of
5.08 mm or more in accordance with UL.
