At last,based on the deep studying of PCB testing method,used the developed multiswithing scanner and software faced testing,combinated with necessary testing instrument ,we constructed the PCB testing system and analized the testing result simply.

• 最后，在深入研究印刷电路板测试方法的基础上，利用已开发的多路通道扫描器和面向测试软件，结合必要测试仪器组建印刷电路板测试系统，并对测试结果进行了简要的误差分析。
