Effect of Destructive Physical Analysis(DPA)Technology on Quality Assurance of Domestic Electronic Components
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 im-ported 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 manufactur-ing process of domestic components.This paper mainly introduces the role of destructive physical analysis(DPA)technolo-gy,and the DPA analysis case of an inductor and a fuse in the early component import stage.
