Feature
- Low thermal resistance
- High reliability
- Easy to handle
-
Low thermal resistance
GraphiteTIM provides as good low thermal resistance as grease even though sheet material.
■Thermal resistance compared to grease with different thermal conductivity
(Thickness of grease is 100 μm)Measuring instrument: TIM Tester ( ANALYSIS TECH, ASTMD5470 compliant )
・Provide thermal resistance equivalent to grease.
-
High reliability
GraphiteTIM maintains high reliability for a long period compared to a grease because of its property of hardly changing thermal resistance.
■Negative impact on the reliability due to pump out phenomenon
Pump-out test Heat cycle ( -40⇔100°C ) Material Initial 120 times Deterioration
(Thermal resistance)Grease Significantly deteriorated GraphiteTIM Slightly deteriorated ・Pump-out does not occur and characteristic does not deteriorate much.
-
Easy to handle
GraphiteTIM is easy to handle and control, such as inventory control, repair, and processing, since it is a sheet type product.
■All you need to do is fix with screws
・GraphiteTIM eliminates the need for an application process.
・Customization, such as hole making, and repair work are available.
Reference: Comparison with conventional PGS
●Thermal resistance comparison
●Power module
・High compressibility property helps to reduce contact thermal resistance due to better fitting to uneven surface
Recommended applications
For cooling/heat transfer of electronic devices that generates heat, such as power module.
