چکیده انگلیسی
This work presents the characterization of a thermal interface material consisting of an array of mercury microdroplets deposited on a silicon die. Three arrays were tested, a 40Â ÃÂ 40 array (1600 grid) and two 20Â ÃÂ 20 arrays (400 grid). All arrays were assembled on a 4Â ÃÂ 4 mm2 silicon die. An experimental facility which measures the thermal resistance across the mercury array under steady state conditions is described. The thermal interface resistance of the arrays was characterized as a function of the applied load. A thermal interface resistance as low as 0.253Â mm2Â KÂ Wâ1 was measured. A model to predict the thermal resistance of a liquid-metal microdroplet array was developed and compared to the experimental results. The contact resistance of the mercury arrays was estimated based on the experimental and model data. An average contact resistance was estimated to be 0.14Â mm2Â KÂ Wâ1.
