To draw a good thermal resistance from sheet, pressure the GraphiteTIM.
A close adherence would make the product fit into the uneven part and
enhance the performance.

What is PGS Graphite sheets(GraphiteTIM)?
A type of graphite made from Carbon, an artificial flexible graphite sheet developed by Panasonic ⇒Merit factors: light weight, high intensity, high stability, low environmental impact
Basic functions of Thermal protection sheet
- 1. Heat transport
- 2. Thermal interface
How heat is transferred
GraphiteTIM reduces temperature rise
- ＜Power IC＞
Features of GraphiteTIM
- 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.
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℃ ) Material Initial 120 times Deterioration
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
・High compressibility property helps to reduce contact thermal resistance due to better fitting to uneven surface
For cooling/heat transfer of electronic devices that generates heat, such as power module.
