At present, the serial production of radio-electronic equipment has a need for quick and accurate testing in order to improve the quality of products. This article proposes a method for determining the location and nature of a defect in electronic components, which allows you to quickly and accurately identify various kinds of defects that occur during the production process. The method is based on the method of analog signature analysis, which makes it possible to determine changes inside electronic devices at the component level. In the process of testing, the analog signatures were translated into n‑dimensional space and the projections were compared by calculating the distances between the located points. As a result of testing, a digital twin of the tested electronic module is created and its validation with a circuit model is implemented. Possible defects are selected from a library of defects prepared in advance for a given electronic module of radio-electronic equipment, which makes it possible to determine the type and location of the defect.

The results can be applied in the production of radio-electronic equipment in order to improve the quality of products, as well as in the diagnosis of radio-electronic equipment already in operation.
