Thermal interface materials (TIMs) are generally used to reduce the thermal resistance between contacting surfaces in electronic devices. The thermal properties of these materials
such as thermal conductivity (kTIM) and contact resistance (Rc) at the TIM-solid interface
are critical to the heat dissipation analysis. However
it is much difficult to obtain these data. In this paper
an experimental apparatus for TIMs thermal properties measurements is built based on ASTM test standard D-5470. Using this apparatus
kTIM and Rc of the silicone oil and thermal greases are measured
respectively. According to the error analysis
the relative errors in the measurement of kTIM and Rc are less than 11.3% and 41.3%
