了解在线测试仪的读者，均知道有这么一句行话。“在线测试时不通过的芯片不一定是损坏的；测试通过的芯片一定是没有损坏的。”它的解释为，如器件受在线影响或抗干扰时，结果可能不通过，对此不难理解。那么，是否损坏的芯片在进行测试时，均会得出“不通过”呢？回答确实不能肯定。笔者与同行均遇到过，明明芯片已损坏了（确切地说换上这个芯片板子就不工作了），但测试结果是通过的。权威解释为这是测试仪自身工作原理（后驱动技术）所致。故此我们不能过分依赖在线测试仪（尽管各厂家宣传的很玄）的作用，否则将使维修电路板的工作误入歧途。 
维修技巧之二  
    在无任何原理图状况下要对一块比较陌生的电路板进行维修，以往的所谓“经验”就难有作为，尽管硬件功底深厚的人对维修充满信心，但如果方法不当，工作起来照样事倍功半。那么，怎样做才能提高维修效呢？根据我公司进口设备维修中心统计出来的资料，应遵循以下几个步骤、按顺序有条不紊的进行。
