Electronic technology is an emerging technology that began to develop at the end of the 19th century and the beginning of the 20th century. In the 20th century, it developed most rapidly and was widely used. It has become an important symbol of the development of modern science and technology. With the increasing requirements for the quality and reliability of electronic products, the reliability of electronic components continues to attract people's attention. How to improve the reliability has become a hot issue in the manufacturing of electronic components.

The purpose of reliability work is not only to understand and evaluate the reliability level of electronic components, but also to improve and improve the reliability of electronic components. Therefore, after obtaining the failed device from the use site or reliability test, it must be tested and analyzed to find and determine the cause of failure, feed back the analysis results to the design, manufacturing, management and other relevant departments, and take targeted and effective corrective measures to improve and improve the reliability of the device. This kind of test analysis, the process of finding the failure cause or mechanism, is failure analysis.

In electronic circuits, in addition to the most contacted electronic components (such as resistors, inductors, capacitors, diodes, triodes, integrated circuits, etc.), there are other commonly used electronic components, such as electroacoustic devices, switches and connectors. Failure analysis is the process of diagnosing the failure mechanism and causes of electronic components, and it is the only way to improve the reliability of electronic components. Components from design to production to application are likely to fail, so failure analysis runs through the whole life cycle of electronic components. Therefore, it is necessary to find out the cause of its failure, determine the failure mode, and put forward corrective measures to prevent the same failure mode and failure mechanism from recurring on each component, so as to improve the reliability of components.

The detection of electronic components is a basic skill of home appliance maintenance. Many engineering maintenance and repair technologies in the security industry are actually from the maintenance and repair technology of home appliances, or reference or homogeneous. How to accurately and effectively detect the relevant parameters of components and determine whether the components are normal is not a stereotype. Different methods must be adopted according to different components to judge whether the components are normal or not. Especially for beginners, it is necessary to master the testing methods and experience of common components.

Failure analysis plays an important role in ensuring and improving the reliability and quality of products. It is necessary to introduce failure analysis in the research and development, production and use of products. Analyze the failure causes of semiconductor devices, and provide scientific basis for accident liability identification, criminal case detection, compensation award, insurance business, product quality standard modification, etc; Reduce and prevent the repeated failure of similar mechanical parts and components, ensure product quality and improve product competitiveness; Provide information for enterprise technology development and technological transformation, increase the technical content of enterprise products, and obtain greater economic benefits.
