摘　　要：重点讨论了飞针在线测试技术在电子模块测试中的应用,并分别介绍了模拟器件和数字器件的测试方法。此技术能测试被测电子模块上各器件之间的物理连接,能测试模拟器件的值,同时也能测试数字器件的逻辑关系。此技术采用了基于PC机软件编程方法,使得测试程序化,并采用隔离技术将被测器件分离,提高测试精确度。灵活的软件编写也使得调试方式多样化。飞针测技术的使用能准确定位故障点,缩短调试周期,对小批量生产的电子模块调试有重要作用。The paper tion,it introduces the test device＇s value and digital ceeding. It adopt guarding focuses on the implementation of flying probe test system in the electronic board test. In addimethod of analog devices and digital devices. It can test all the devices＇s physical links, analog device＇s logic relations. It adopt programming technologies based on PC which made test protechnique permit to isolate a single component from the rest of the circuit while testing it, which increasing the precision of testing. The flexible program method made the debug diversification. This machine can find faulty quickly, shorting the debug cycle ,it is useful for batch electronic boards＇ debugging.
