工业电路板维修技巧
不能过分依赖在线测试仪
1.功能测试不能代替参数测试
2. 功能测试仅能测试到器件的截止区，放大区和饱和区，但无法了解此时的工作频率的高低和速度的快慢。
3. 对数字芯片而言，仅知道有高低电平的输出变化，但无法查出它的上升和下降沿的变化速度。
4. 对于模拟芯片，它处理的是模拟的变化量。其受电路的元器件的分布，解决信号方案的不同的影响，是错综复杂的。就目前的在线测试技术，要解决模拟芯片在线测试是不可能的。所以，这项功能测试的结果，仅能供参考。
5. 大多数的在线测试议，在对于电路板上的各类芯片进行功能测试后，均会给出“测试通过”或“测试不通过”。那么它为什么不给出被测器件是否有问题呢？这就是这类测试仪的缺撼。因为在线测试时，所受影响（干扰）的因素太多。要求在测试前采取不少的措施（如断开晶振，去掉CPU和带程序的芯片，加隔离中断信号等等），这样做是否均**，值得研究。至少，目前的测试结果有时不尽人意。
6. 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。

为什么有诸多企业在智能制造转型过程中仍在“摸着石头过河”？石安认为：其中最核心的挑战是产能过剩、高度同质化以及需求疲软。
今年，在罗克韦尔自动化发布的第八版年度《智能制造现状报告》中提出，技术对于减轻风险和实现增长至关重要。然而，三分之一的制造商仍面临着可用系统和平台的范围受限，从而导致“技术瘫痪”，即无法在各种解决方案之间做出决定。因此，拥有具有相关行业专业知识和经验的合作伙伴对于企业实现智能制造升级也十分重要。 |
