Research on Inspecting Opportunity for Reliability Goals

Abstract

Compared with the reliability minimum acceptable values inspected on the design finalization phase, the concern is that, whether the goals should be inspected on the manufacture finalization phase or not? This paper introduces the definition for reliability goals, thresholds and so on in GJB 1909A on the basis of the growth rule of product reliability during the life cycle, and explains manufacture finalization mentioned in some documents such as GJB 1362A. It points that the manufacture finalization’s objective is to examine quality stability and conditions for complete set and batch production to make the decision whether produce by batch or not. On this basis, it discusses the inspecting opportunity for reliability goals in detail. Finally, the conclusions are given, that reliability goals can’t be inspected on the manufacture finalization phase, for the products aren’t still mature on this phase. When the products have been serviced for a period, the equipment design defects and process defects are fully exposed and improved, and the products’ quality is stable, then the goals can be inspected.
