DC/DC power module failure analysis study

This paper analyzes a large amount of component failure data and finds that the failure of DC/DC power modules has extremely high research value. By analyzing the failure models of DC/DC power modules, it is found that their failure is closely related to circuit functions, internal components, and packaging seal integrity. This paper introduces the analysis methods for DC/DC power modules with specific cases, revealing the failure patterns of DC/DC power modules, thereby improving the reliability level of electronic devices.
