3. Mounting to heat sink
3-1. Surface conditions of heat sink Design the heat sink so that the following surface conditions are satisfied. If the roughness and
flatness do not satisfy the conditions, it may cause an increase in contact thermal resistance, or insulation failure due to package cracking.

1. The surface roughness(Rz) of the heat sink should be 10m or less. 2. The surface flatness of the heat sink should be 50m or less in absolute value per 100mm,
taking the straight line connecting the center points of the two screw mounting holes as reference. Here, “+” (plus) is defined when the heat sink has a convex shape, and “-” (minus) is defined when the heat sink has a concave shape. If both shapes exist, the sum of the absolute values of the maximum and minimum values should be 50m or less. * The flatness must satisfy the above value within the entire module mounting area including the two screw clamps.

Fig.1 shows the definition of surface roughness and flatness of the heat sink.

The surface flatness should be 50m or less per 100mm, taking the straight line connecting the center points of the two screw mounting holes as reference.

3-2. Application of thermal grease Thermal grease must be applied between the product mounting surface and the heat sink to ensure heat dissipation from the product to the heat sink. Thermal grease should be applied to the mounting surface of the product. Improper thermal grease characteristics, application amount, and application method can lead to thermal breakdown due to deterioration of heat dissipation caused by thermal grease not spreading sufficiently throughout the product, or to a reduction in product life due to degradation or depletion of thermal grease during high temperature operation or temperature cycling. Pay attention to the selection and application method of the thermal grease. Assuming that the thickness is uniform, the required amount (weight) of thermal grease can be calculated from the following formula.

Thermal grease weight (g) x 104

=

Thermal grease thickness (m)

x

Base plate area module (cm2)

of

x

Density of thermal grease (g/cm3)

The stencil method of application is recommended to control proper thickness (Figure. 2). The recommended stencil mask pattern (Table 4) can be provided upon request. The spreading of thermal grease can be checked by removing the product after mounting. Make sure that the thermal grease is well spread over the entire product mounting surface. When applying thermal grease, should check not only the spread of the thermal grease over the entire surface of the product, but also the heat dissipation of the product.
Fuji Electric confirmed that the spreading which is not a problem in actual use using ELECTROLUBE’s HTC thermal grease with our specified stencil masks and heat sinks of the shape described in our specifications. Table 5 shows typical characteristics of HTC thermal grease.
Additionally, the use of phase change thermal interface material and thermal sheet may cause excessive stress on the product as described below.
– Phase change thermal interface material : When the grease solidifies, its hardness increases significantly compared to normal thermal grease. If there is a step between the fastening points due to the grease, the product may be subjected to excessive stress at the step when fastening the product. To reduce product stress during fastening, consider measures such as increasing the fastening torque in stages, fastening while heating and softening the grease. After the grease softens and spreads, the tightening torque may decrease. Consider measures such as retightening within the specified torque range or using spring washers.
– Thermal sheet : If there is a step between the fastening points due to the sheet, the product may be subjected to excessive stress at the step when fastening the product. Please consider placing the sheet over the entire backside of the product, including around the heat sink fastening screw holes.
The above explanation shows the basic concept of thermal grease, but when using it, customer is responsible for making the decision to apply it with sufficient application verification.

4. Mounting the module to printed circuit board
4-1. Soldering to printed circuit board The recommended soldering conditions for mounting a printed circuit board (PCB) on the module are shown below.
Terminal temperature: 245 ± 5oC Time: 5 ± 0.5 sec
However, since the definition of the recommended soldering temperature is “terminal temperature”, it is different from the set temperature of the soldering machine. Set the soldering unit temperature to suit the heat capacity of your PCB. Before soldering, make sure that the temperature of the resin part at the base of the product terminal is 260°C or less.

6. Storage and transportation notes
6.1 Storage (1) Please manage the storage location so that the temperature is 5 to 35°C and the humidity is 45 to 75%. If more than a year has passed since the product was manufactured under these storage conditions, confirm that the terminal solderability is not deteriorated before mounting. (2) Avoid exposure to corrosive gases and dust. (3) Rapid temperature changes may cause condensation on the product surface. Therefore, store products in a place with minimal temperature changes. (4) During storage, it is important that nothing be placed on top of the products, since this may cause excessive external force on the case. (5) Store products with unprocessed terminals. Corrosion may form causing processed connections to have high contact resistance or potential solder defects in later processing. (6) Use only antistatic containers for storing products in order to prevent ESD damage.
6.2 Transportation (1) Do not drop or cause impact to the products which could otherwise cause mechanical stress. (2) When transporting several products in the same box or container, provide sufficient ESD padding between the products to protect the terminals and to keep the products from shifting.
