Below are the Test Methods employed by Fujipoly.
Test Method of Thermal Conductivity by ISO / CD 22007-2
Fujipoly Test Method: FTM P-1612 (Hot Disk method)
Test Methods of Thermal Conductivity by ASTM D2326 equivalent
Fujipoly Test Method: FTM P-1620 (Hot Wire method)
The probe of which the thermal conductivity is known is put on the specimen. Then the hot wire is given constant electric power.
Thermal conductivity is calculated by software for calculation.
|Specimen||Thickness —||0.1 to 2.0 mm|
|Width x Length —||Min. 120 x 60 mm|
A thermal conductivity is given by the equation below.
|Thermal Conductivity meter||QTM-D3|

Test Method for Thermal Resistance by Fujipoly Original
Fujipoly test method: FTM P-3010(TO-3 method) which gives ASTM D5470 equivalent value.
1. Test Method
2) 20 Watt power is applied to the transistor.
3) After three minutes, the thermal resistance is calculated based on the following formula (B).
- 1) Punched-out specimen in TO-3 package is located between a transistor and heat sink, and secured with screws the position (A),using a screwdriver.
- 2) 20 Watt power is applied to the transistor.
- 3) After three minutes, the thermal resistance is calculated based on the following formula (B).
Formula for Thermal Resistance calculation.
|(B)||: Rt = ( Tc –Tf ) / P0|
|Rt||: Thermal resistance K-in2 / W)|
|Tc||: Transistor temperature (K)|
|Tf||: Heat sink temperature (K)|
|P0||: Heat flow (W)|
Test Method of Compression Force by ASTM D575-91(2012)
1. Test Method
Compression test in which the force required to cause a specified deflection is determined.
2. Test Condition
Thickness is according to each materials
