摘要

為了確保產品可靠度符合可靠度目標，產品上市後，必須持續追蹤產品在顧客端使用的可靠度水準及潛在的重大可靠度問題。本研究運用統計方法，分析故障資料及評估故障率，以建立完整的產品場域可靠度監測系統與場域可靠度問題的調查程序。藉由廠內監督及從顧客反映的產品可靠度問題，以產品或零件的故障率是否超過可靠度目標，作為展開故障原因調查及提出改正措施的決定條件。可靠度工程師因此可以有效預防及解決可靠度問題，達成顧客所要求的可靠度水準。本研究以交換式電源供應器為例，對研究目標進行深入探討。

In order to ensure product to meet its reliability goal, product field reliability level and potential significant field reliability issues should be monitored consistently after its deployment to the market. In this study, a complete field reliability monitoring system and field reliability issues investigation process based on statistical analysis on failure data and failure rate assessment are developed. Built on information from producer's internal reliability monitoring and customer's feedback of reliability issues, the product and its components field failure rates are compared with corresponding reliability targets, a decision can be generated for initiation of root cause investigation and development of corrective action. Reliability engineer can effectively prevent and resolve field reliability issues to meet customer expected product reliability level. This study uses switching power supply as a case study to perform detailed exploration on the research objectives.
