归零工作对提升产品可靠性的效用研究

Research on Utility of Close Loop to Improve Product Reliability

随着我国航天型号产品使用严酷度的逐步升级,对产品的质量等级和使用寿命的要求也越来越高。为了提升产品固有可靠性,满足航天产品的高可靠要求,文章阐述了质量归零工作的要求和具体内容,并以两个在可靠性试验和用户使用中出现的偶然失效问题为例,通过归零研究,找到了影响器件长期可靠性的问题根源及解决措施。这为提升产品的设计和工艺技术平台能力,持续改进产品的质量,促进产品固有可靠性的提升起到了积极作用。

With the escalating of severe degree of the use of aerospace products in China,the demand for the quality grade and service life of components is also getting higher and higher.In order to improve the inherent reliability of products,and to meet the high reliability requirements of aerospace products,this paper expounded the requirements and detailed contents of product quality’s close loop method,and took two accidental failure examples in long-term reliability test and using process.By the close loop method,the primary causes of the problems which affected the long-term reliability of the device and its solution measures were found.The results were helpful for improving the capabilities of design and process platform,continuously improving the product’s quality,and promoting the inherent reliability of products.
