Abstract: Electronic devices are indispensable parts of all kinds of high-tech equipment in the aerospace field. Different from the obvious degradation characteristic of mechanic equipment, there is no obvious external manifestation of the degradation state of electronic equipment. There is no effective sign to characterize the state, and there are certain difficulties in fault prediction and health management of the equipment. To overcome this problem, this paper distinguishes the basic concepts and connotations, introduces the latest research trends home and abroad, and analyzes the current challenges and countermeasures in prognostic and health management of electronic equipment. The new characteristics of future complex electronic equipment and the latest research progress in this field are discussed. Three new development directions for prognostic and health management technology for electronic equipment are proposed, including health state assessment based on intermittent fault characteristics, testability design for prognostic and health management, and health state prediction based on multi-source information.

Key words: electronic equipment, fault prediction, health management, testability design, intermittent fault characteristic
