电子元器件 可靠性 失效率和应力模型的基准条件

[中文适用范围]： 本国际标准为使用故障率数据来预测电子设备中组件的可靠性提供了指导。规定了故障率数据的参考条件，以便不同来源的数据可以在统一的基础上进行比较。如果按照本标准给出故障率数据，则不需要有关指定条件的附加信息。本标准中描述的应力模型应作为将参考条件下的故障率数据转换为实际运行条件的基础。仅允许在组件的指定功能限制内转换故障率数据（参见附录 A）。 [外文原描述]： Gives guidance on the use of failure rate data for the reliability prediction of components in electronic equipment. Reference conditions for failure rate data are specified, so that data from different sources can be compared. The reference conditions adopted are typical of the majority of applications of components in equipment (e.g. telecommunication use, data processing). In this standard it is assumed that the failure rate used under reference conditions is specific to the component i.e. it includes the effect of complexity, technology of the casing, dependence on manufacturers and the manufacturing process, etc.
