平均无故障工作时间间隔至少大于1000小时作为电子测量仪器老产品升级换代的一项技术指标已经提出来了。本文拟以提高UX2振荡器、UD9选频表可靠性做的一些工作讨论,而后提出目前适用于工厂对具体测量仪器老产品可靠性工作的开展的粗浅看法。一、现场数据的收集缺乏必要的可靠性试验及失效分析手段,在产品的失效原因不详,反馈纠正周期
MTBF is at least 1000 hours as a technical indicator of the upgrading of old products of electronic measuring instruments has been proposed. This article intends to improve the UX2 oscillator, UD9 frequency table to do some of the reliability of the work to do, and then put forward for the current plant for the specific measurement of the reliability of old products to carry out the work of the crude view. First, the collection of on-site data Lack of necessary reliability testing and failure analysis tools, the cause of the failure of the product is unknown, the feedback correction cycle
