Abstract : The objective of this study was to evaluate Environmental Stress Screening (ESS) techniques contained in DOD-HDBK-344, by applying the methodology to several electronic products during actual factory production. Validation of the techniques, the development of improved, simplified, and automated procedures and subsequent revisions to the Handbook were the objectives of the evaluation. The Rome Laboratory has developed techniques which enable users to plan, monitor, and control ESS PROGRAMS. These techniques were previously documented in DOD-HDBK-344, ESS of Electronic Hardware. The basic approach to the ESS process used in the Handbook focuses on the latent defect population of the hardware, and on developing a cost-effective, statistically controlled ESS process aimed at reducing the defect population so as to achieve quantitative field reliability requirements. As a result of the study: the effectiveness of the Handbook methodology and techniques was confirmed and validated; recommended changes, additions, and deletions were incorporated into a revision of the Handbook and software package was developed to facilitate application of the procedures.
