基于VI曲线测试的电路板故障诊断技术

Fault Diagnostic Technology of Board Based on VI Curve Testing

VI曲线测试是一种基于电路VI特性曲线的有效快捷的电路板及元器件测试维修技术,通过检测电路或器件的VI特性曲线,来定位故障点。研究VI曲线测试的特点,并介绍电路板VI曲线测试具体实现方法和操作技巧。

VI curve testing is a kind of circuit boards and components test repairing technology based on VI characteristic curve. Through the detection of the VI curves, VI curve testing can locate the fault point of circuit or the components. This paper studies the characteristics of VI curve testing and introduces the implementation methods and operation skills of circuit board VI curve testing.
