Improving aerospace electronics by systemic early failure analysis during development and modification

摘要

A three-stage systemic early failure analysis (SEFA) methodology is proposed. It addresses prevalent failures occurring during development using diverse experimental and theoretical techniques and structures. SEFA provides a flexible yet consistent effective and efficient approach leading to a rare combination of unified high quality, reliability, safety, improvement and profitability (QIP). The SEFA impact is maximized when a proper process is implemented at hi-tech mass-produced demanding electronics business. Practical and specific SEFA techniques, classifications and examples substantiate and illustrate the proposed approach.
