Electronic device heat dissipation is crucial and challenging because it limits the performance of the device. The electronic device is processing data at high speed, significantly generate heat and requires to be dissipated into the environment. Therefore, this experiment aims to investigate the influence of thermal interface material hardness on thermal conductivity. The results were analyzed by using conductivity measurement set-up and scanning electron microscopy (SEM) with energy dispersive x-ray spectroscopy (EDX). In the present study, thermal interface material (TIM) is hardened by aluminum oxide (Al@Al2O3) and thermal coefficient are measured for different hardness and the heat rate of 3W and 7W. The results show TIM hardness is significantly improved the thermal conductivity coefficient up to 10 times compare to pure TIM. The results also show that the Al@Al2O3 particles distribution inside the TIM is well distributed. The outcomes of this paper can be a guideline to the semiconductor industries especially for the usage of TIM in product development.
