Performance Comparison: Liquid and Pad Thermal Interface Material
This study tested the hypothesis that a liquid TIM with the same effective thermal conductivity as a gap pad will have lower thermal resistance in application due to its ability to wet out the interface better than a solid pad. Also hypothesize here, bondline thickness has a significant effect over total thermal resistance.
