A survey of the state-of-the-art in aging of electronics with application to nuclear-power-plant instrumentation
Abstract
Research on aging of electronics in nuclear power plants is evaluated. The emphasis is on aging of electronics (e.g., semiconductors, capacitors, resistors) used in safety related Class 1E instrumentation, particularly those used in harsh environments. Some attention is also given to encapsulants, printed circuit boards and bonds (e.g., solder joints) since they are integral parts of circuits. Candidate electronic components were selected. The aging environment was defined and an effort to determine the state of the art in aging degradation was initiated. Follow on investigations and research was recommended and the first steps in defining a program on accelerated aging was outlined.
