1、是否有断线； 
2、分力元件如电阻、电解电容、电感、二极管、三极管等时候存在断开现象； 
3、电路板上的印制板连接线是否存在断裂、粘连等； 
4、是否有人修过？动过哪些元器件？是否存在虚焊、漏焊、插反等操作方面的失误； 
在确定了被修无上述状况后，首先用万用表测量电路板电源和地之间的阻值，通常电路板的阻值都在70-80？以上，若阻值太小，才几个或十几个欧姆，说明电路板上有元器件被击穿或部分击穿，就必须采取措施将被击穿的元器件找出来。具体办法是给被修板供电，用手去摸电路板上各器件的

“西门子的愿景是为用户、工程公司和设备商提供一个环境，我们在这个环境里能够轻松实现IT/OT融合，这是Industrial Operations X的内涵。”谈及西门子基于云的开放式物联网操作系统MindSphere与西门子Xcelerator的关系，西门子(中国)有限公司执行副总裁、西门子大中华区数字化工业集团总经理王海滨介绍到：“几年前，当MindShpere被推出的时候，我们对MindShpere的定义是PaaS（平台即服务）层的平台。当时在数字化转型过程中，数据从机器设备、工厂产线的现场产生，需要把它放到中间平台层。但是在数据连接并且放到平台层的过程中有挺多挑战，比如有数据通信驱动方面的挑战，有数据安全方面的挑战等。为了应对这些挑战，西门子开发了一个工业的数据平台PaaS（平台即服务）层，这就是MindShpere的定位。工业数据到了PaaS层之后，用户可以再开发各种APP，或者APP形成SaaS（软件即服务）服务。”
