Next Generation HALT and HASS

NEXT GENERATION HALT AND HASS ROBUST DESIGN OF ELECTRONICS AND SYSTEMS A NEW APPROACH TO DISCOVERING AND CORRECTING SYSTEMS RELIABILITY RISKS Next Generation HALT and HASS presents a major paradigm shift from reliability prediction-based methods to discovery of electronic systems reliability risks. This is achieved by integrating highly accelerated life test (HALT) and highly accelerated stress screen (HASS) into a physics of failure based robust product and process development methodology. The new methodologies challenge misleading and sometimes costly misapplication of probabilistic failure prediction methods (FPM) and provide a new deterministic map for reliability development. The authors clearly explain the new approach with a logical progression of problem statement and solutions. The book helps engineers employ HALT and HASS by demonstrating why the misleading assumptions used for FPM are invalid. Next, the application of HALT and HASS empirical discovery methods to quickly find unreliable elements in electronics systems gives readers practical insight into the techniques. The physics of HALT and HASS methodologies are highlighted, illustrating how they uncover and isolate software failures due to hardware–software interactions in digital systems. The use of empirical operational stress limits for the development of future tools and reliability discriminators is described. Key
