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。

   日前，开发区博士后科研工作站华恒博士后工作分站成功开发了“带坡口管件的机器人切割离线编程系统”，填补了国内该领域的空白。这是华恒博士后工作分站叶晓明博士后课题取得的阶段性成果。 

    该离线编程系统应用于工业机器人领域，可根据用户提供的切割管件参数，自动生成机器人的离线编程程序，比传统的在线示教精度更高，自动化程度更高，对操作人员的技术要求更低，生产效率得到大幅提高。据悉，拥有该系统将是今后工业机器人的一个重要发展方向。叶晓明表示，今后将带领工作团队，进一步优化该系统功能，并扩展应用于弯管、马鞍形切割以及焊接机器人设备，推动我国工业机器人行业向国际先进水平迈进。
