为了大幅度提高对大规模PCB上元件引脚间通路关系的测量效率,本文介绍一种PCB反设计系统中的探测电路的实现原理,重点分析如何自动地选择被测引脚并测量,如何判断通/断路关系,以及如何自动记录测量结果等问题。
In order to greatly improve the efficiency of the measurement of the relationship between the pins of components on a large scale PCB, this paper introduces a realization principle of the detection circuit in a PCB anti-design system, focusing on how to automatically select the measured pin and measure how to judge On / off relationship, and how to automatically record the measurement results and other issues.
