GraphiteTIM (Compressible Type)

Panasonic highly crystallized graphite, high reliability, easy installation,
unprecedented thermal interface material

Feature

• Low thermal resistance
• High reliability
• Easy to handle

1. 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.

2. 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.

3. 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.

●Thermal resistance comparison

●Power module

・High compressibility property helps to reduce contact thermal resistance due to better fitting to uneven surface
