摘　　要：DC/DC元器件在电源电路中起到调节输入电压,输出理想电压的作用,目前其安装方式主要有安装于印制板(Printed Circuit Board,PCB)以及安装于模块结构件壳体。相较于民用电子设备,机载电子设备在实际工作中会受到高温、高低温循环、振动等负载的影响,从而导致元器件虚焊等失效问题。通过热仿真以及强度仿真对DC/DC元器件的不同安装方式进行详细分析,从而为机载电子设备电源电路的DC/DC元器件安装方式提供参考。The DC/DC component,regulating voltage in power supply circuit,is mainly installed on the Printed Circuit Board(PCB)or the shell.Compared to civilian electronic equipment,airborne electronic equipment has a harsher working enviroment,such as high temperature,temperature cycling,random vibration.Simulation on strength and thermal is used for analyzing the advantages and disadvantages on the different installation methods in this article.
