Research on Failure Modes and Impact Analysis of Key Electronic Components

Analyze the failure mode of electronic components, find the type of stress that causes the failure of the energy meter, trace the key components that cause the fault, and complete the failure mode and impact analysis of key electronic components through failure detection means and failure analysis experiments. In order to develop a reliable product, it is necessary to understand the potential failure mechanism of the product. Modeling to describe the relevant failure modes can promote the development of product design principles. The research results of failure mechanism are not only conducive to improving the reliability manufacturing level of domestic electric energy meter, but also can save the maintenance and transformation cost of electric energy meter, and have very important practical significance for the construction of smart grid.
