摘　　要：由于中美贸易争端和技术限制,以及台海危机等引发的供应风险,迫使电子元器件供应链转向国内,电子元器件国产化发展已成必然趋势。但是国产元器件与国外进口元器件之间的各方面差异,无法用常规的鉴定方法进行有效区分,所以在国产化替代时,出现了替代难、不敢替代等情况。破坏性物理分析(DPA)作为一项重要的技术手段,以预防失效为目的,分析评估国产化元器件是否存在工艺、材料或制程等各环节的缺陷。主要介绍了DPA技术的作用,以及在前期元器件导入阶段对某电感和某保险丝的DPA分析案例。Supply risks arising from the Sino-US trade dispute and technological constraints,as well as the Taiwan Strait crisis,have forced the supply chain of electronic components to turn inward,and the localization of electronic components has become an inevitable trend.However,the differences in various aspects between domestic components and foreign imported components cannot be effectively distinguished by conventional identification methods,so it is difficult to substitute and dare not substitute when the domestic components are substituted.Destructive physical analysis(DPA),as an important technical means to prevent failure,analyzes and evaluates whether there are defects in the process,material or manufacturing process of domestic components.This paper mainly introduces the role of destructive physical analysis(DPA) technology,and the DPA analysis case of an inductor and a fuse in the early component import stage.
