A Study on ESS Process Modeling and Application for Improving Reliability of Electronic Equipments

Defense Agency for Technology and Quality(DTaQ) Purpose: In this study, we propose the ESS process model which, in order to improve reliability of electronic equipment, can be referenced in both development and production phases.Methods: ESS guidelines such as MIL handbooks or private sector ESS gui delines are used for devising the proposed ESS model. Especially, proposed model is customized by using those references in order to be optimized in the domestic development and production phases.Results: ESS-related-requirements which is specified in the Technical D ata Package(TDP) for the area of guided missile systems are analyzed. Current status of the requ irement and screening strength are analyzed for those systems to show what kind of weak points should be im proved.Conclusion: A ESS guideline which is applicable to the domestic weapon acq uisition environment is proposed. As such, the necessity and detail guidelines of the proposed mo del are explained.Key Words：Environmental Stress Screening(ESS), ESS profile, ran dom vibration, thermal cycling, Technical Data Package(TDP)
