font-family: 宋体; box-sizing: border-box !important; word-wrap: break-word !important;">、核磁等机器本身都自带程序能检测机器故障的大概原因，一部分电路板的故障可以通过运行检测程序检测出来。电路板在线测试仪是一种基于计算机技术的新型维修工具，可对电路板上的各种数字集成电路和</span><span style="max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;">IC</span><span style="max-width: 100%; font-family: 宋体; box-sizing: border-box !important; word-wrap: break-word !important;">进行功能测试、型号识别，利于准确判断损坏元器件，减少整体换电路板的高额费用。数字示波器具有抗干扰强，测试准确的优点，可测频率等多项参数，采集并储存电路板的关键点的波形和数据，一旦仪器发生故障，可调出正常值对比，最快地修复仪器故障。</span></span><span style="max-width: 100%;

letter-spacing: 0pt; font-size: 10.5pt; font-family: Arial; box-sizing: border-box !important; word-wrap: break-word !important;">电路板的维修分为整体维修和电路板上的电子元器件的维修。整体维修就是用一块好的电路板将其替换下来，使设备能够恢复正常工作，这种维修极少采用。电子元器件的维修，医疗电子设备上的每一块电路板上都由许多元器件组成，如：电阻、电容、二极管、各种集成块等，通过检测发现电路板的故障器件，更换后电路板就能恢复正常。</span><span style="max-width: 100%;
