可靠性应力筛选第2部分:部件

[中文适用范围]： 本部分IEC 61163提供了电气、电子和机械组件可靠性应力筛选（RSS）技术和程序的指南。本文件在性质上属于程序性，由于组件行业发展的快速速度，不能也不可能是有关组件技术的 exhaustive（详尽）文件。 本文件： a) 旨在为组件制造商作为指南； b) 旨在为组件用户作为与组件制造商谈判RSS要求的指南； c) 旨在允许计划内部RSS过程以满足可靠性要求，或允许为特定、升级的环境重新认证组件； d) 旨在作为向提供RSS服务的承包商的指南。 本文件不旨在为特定组件提供测试计划，也不旨在为组件批次提供符合性证书。 文中描述了利用双模Weibull分析来选择和优化RSS过程，而无需估算所有项目的可靠性和寿命。 [外文原描述]： IEC 61163-2:2020 provides guidance on RSS techniques and procedures for electrical, electronic, and mechanical components. This document is procedural in nature and is not, and cannot be, exhaustive with respect to component technologies due to the rapid rate of developments in the component industry. This document is: a) intended for component manufacturers as a guideline; b) intended for component users as a guideline to negotiate with component manufacturers on RSS requirements; c) intended to allow the planning of an RSS process in house to meet reliability requirements or to allow the re-qualification of components for specific, upgraded, environments; d) intended as a guideline to sub-contractors who provide RSS as a service. This document is not intended to provide test plans for specific components or for delivery of certificates of conformance for batches of components. The use of bi-modal Weibull analysis to select and optimize an RSS process without having to estimate the reliability and life time of all items is described. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) this version of the document is a complete rewrite and restructure from the previous version.
