摘要
将倒装芯片(Flip Chip,FC)技术引入三维集成电力电子模块(Integrated Power Elec-tronic Module,IPEM)的封装,可构建FC-IPEM。在实验室完成了由两只球栅阵列芯片尺寸封装MOSFET和驱动、保护等电路构成的半桥FC-IPEM。针对半桥FC-IPEM,建立半桥FC-IPEM的一维热阻模型,分析模块主要的热阻来源。运用FLOTHERM软件进行三维仿真,得到模块温度分布结果,给出优化模块热性能的依据。
Flip chip (F C) technology was used for packaging three-dimensional integrated power electronics module (IPEM) to fabricate FC-IPEM. A half-bridge (HB) FC-IPEM consisting of two ball-grid array chip-size packaged MOSFETs, corresponding gate driver and protection circuits was realized. One-dimensional thermal resistance model of HB FC-IPEM was built to analyze thermal resistance source. Simulation was made by using FLOTHERM to obtain thermal distribution of the module, and design strategies to optimize thermal behavior of the module were given.
