随着电子技术设备在铁路各系统的广泛应用,电子电路板的测试维修手段也在不断更新。本文将对电子仪器和设备内电子电路板做器件级检修时,所采用的维修方法进行探讨。电子仪器、设备的检修,一般分为“板级”和“器件级”。“板级检修”是当设备中电子电路发生故障时,通过设备自 With the extensive application of electronic technology and equipment in various railway systems, the testing and maintenance methods of electronic circuit boards are constantly being updated. This article will electronic equipment and electronic devices within the device-level circuit board maintenance, the maintenance methods used to be explored. Electronic equipment, equipment maintenance, generally divided into “board level” and “device level.” “Board Level Overhaul” is a device that passes through the device when an electronic circuit in the device fails
