摘要: 研究多芯片组件(Multi-chip Module,MCM)各元器件之间热传导的相互影响,建立了在对流空气条件下,一种基于结环热阻矩阵的MCM各元器件结温数学计算方法,并利用有限元模拟方法根据不同组合条件对结环热阻矩阵进行验证,结果表明采用结环热阻矩阵预测元器件结温的误差小于6%,说明该方法在某种程度上可运用于对流空气条件下MCM组件的热学分析技术中.

Abstract: It investigated the influence of heat exchange between each chip on MCM, and presented the mathematical calculation method for the junction-temperature of MCM chips under the condition of air convection, based on junction-ambient thermal resistance matrix. Comparison between the results of ANSYS finite element simulation and calculated results via this method under different combination conditions shows that the error margin of junction-temperature forecast by junction-ambient thermal resistance matrix is less than 6%, which indicates that the junction-ambient thermal resistance matrix can be applied to heat analysis for MCM to some extent.

Key words: multi-chip module(MCM); junction-ambient thermal resistance matrix; junction temperature; finite-volume method(FEM);thermal analysis
