On the Principles of Vibration Screening of Deliverable Equipment

The publication in the Spring of 1979 of NAVMAT P–9492 “Navy Manufacturing Screening Program” engendered a very significant increase in the use of Environmental Stress Screens of Electronic Hardware (ESSEH), particularly in the area of vibration screens. Such screens are employed to remove manufacturing defects and eliminate infant mortality failures prior to delivery. This paper will review the principles which govern the selection of suitable vibration screens; those areas where reasonable understanding has been achieved; and those areas where significant advances are still required. The presentation will include an update based on the output from the Third ESSEH Conference and Workshop, September 10-13, 1984, sponsored by IES.
