Use of electronic components with expired storage period
Abstract
Due to the fact that the production and commissioning of military equipment takes considerable time, the problem arises of using electronic components that were discontinued during the product design process. To solve this problem, studies are carrying out to assess the possibility of extending the shelf life of electronic components.
