Abstract : An improved Environmental Stress Screening (ESS) process was developed for electronic equipment. A Process Analysis Technique was used to map the processes documented in five popular ESS guidebooks. A more effective and efficient overall process was then developed by combining the best elements of the individual processes. The five guidebooks studied include: 'Tri-Service ESS Guidelines', Mil-Hdbk-344, "ESS of Electronic Equipment', Institute of Environmental Sciences, 'ESS Guidelines for Assemblies', TEOOO-AB-GTP-O2OA, "ESS Requirements and Application Manual for Navy Electronic Assemblies and NAVMAT P-9492, "Navy Manufacturing Screening Program'. For each guidebook listed above, top level activity flow charts were developed. Inputs and outputs for each activity are illustrated and explained. This provided an explicit set of clearly defined processes that were then studied and improved upon. The process description approach has several advantages. It enables improvement of the individual ESS processes, or as explained above, generation of a grand, optimized process. It provides a tool to aid in understanding the ESS discipline. It also provides a baseline for automation. This report was co-authored by United States and South Korean engineers working together under the auspices of the United States/Republic of Korea Engineer and Scientist Exchange Program (US/ROK ESEP).
