电子产品设计是一个系统性的问题,设计人员的注意力只集中到了原理的设计,注重产品的电性能指标。对于元器件、原材料的膨胀系数匹配问题容易忽视。本文从元器件、基板、焊料等材料膨胀系数的匹配问题入手,对此问题进行了分析。解决了在产品使用中由于膨胀系数不匹配可能会造成的质量问题。
- Abstract:
- Electronic product designing is a comprehensive problem. Some designer pay more attention to the principle of product, with focus on the electricity performance index only ,when they designed,but ignore the CTE matching with component and material. This paper analyse this problem from the CTE matching with the component,the base-plate and the solder material. To slove the quality matter by any possibility in use, because of the CTE mismatching.
