美国国防部实施的空军现场可靠性评价计划最近有了新的进展.从1987年开始国防部就与空军后勤中心及国防电子供应中心密切合作,为该计划收集有关微电子现场失效的各种信息.该计划主要着重于消除现场失效的根源,改进系统的现场可靠性,减少维修费用.该计划是通过维修数据库和到现场检查设备来找出高更换率的元器件,并通过电分析和材料分析来确定其失效机理.修正措施主要集中在元器件和设备的设计、生产、试验、筛选和采购等各种活动中.微电路生产厂、政府零部件采购部门以及后勤中心之间的合作是卓有成效的.该计划对现有及新出现公司以及非国防部政府的现场返修计划都进行了调查.到目前为止,从
Recent developments have been made in the Air Force field reliability evaluation program conducted by the U.S. Department of Defense, which since 1987 has worked closely with the Air Force Logistics Center and Defense Electronics Supply Center to collect various pieces of information about the field failures of microelectronics The program focuses on eliminating the root causes of on-site failures, improving on-site system reliability and reducing maintenance costs through the maintenance of the database and on-site inspection equipment to identify high exchange rate components, and by electrical analysis and materials Analysis to determine the failure mechanism.The correction measures are mainly concentrated in the design, production, testing, screening and procurement of components and equipment, etc. The cooperation between the micro-circuit manufacturing plant, the government procurement of parts and components and the logistics center is Effective.The plan for the existing and emerging companies and non-Defense Department on-site rework plans were investigated.So far, from
