航空电子元器件二次筛选与印制板组件检验

Aviation electronic components and printed circuit board assembly secondary screening test

本文就如何利用外加应力或用检测手段进行二次筛选,将早期失效的元器件从整批产品中剔除,从源头上确保电子产品的质量和寿命。以及在元器件质量和可靠性得到充分保证的前提下,如何不断提高印制板组件加工和检验水平进行了探讨。通过二次筛选以及提高印制板组件加工和检验水平,可以提升模块乃至整机的质量从而使航空电子产品的质量得到充分保证。

This article on how to use the applied stress or secondary screening by means of detection, early failure of components will be removed from the entire batch of products to ensure quality and longevity of electronic products from the source. And in the quality and reliability of the components are fully guaranteed under the premise of how to continuously improve the level of PCB assembly and testing process were discussed. Through secondary screening and to improve the level of PCB assembly and testing process, you can improve the quality of the module as well as the machine so that the quality avionics products are fully guaranteed.
