资料介绍

X射线荧光光谱仪(XRF)在国内的冶金、矿山等行业的实验室有着广泛的应用。以ARL9900系列X射线光谱仪为例,介绍了其XPS电路板上光耦合芯片和XPSI电路板上IGBT芯片损坏故障的故障现象和报警信息,以及如何利用电路原理和电子知识进行电路板上损坏元件的检查和处理。通过这两个典型的电路板芯片级故障处理方法,为实验室精密仪器的芯片级故障修复提供一种思路,帮助企业快速恢复生产,节约备件成本。

X-ray fluorescence spectrometer (XRF) has been widely used in laboratory of some industries such as metallurgy and mining. In proposed study, ARL9900 series XRF was used as an example. The fault phenomenon and alarm information of optical coupling chip on XPS circuit board and IGBT chip on XPSI circuit board were introduced. The checking and treatment of damaged components on circuit board using circuitry principle and electronic knowledge were also introduced. The treatment method of chip-level fault on two typical circuit boards provided a new ideal for the chip-level repairing of precise instruments in laboratory. It could help the enterprises resume the production rapidly and save the cost of spare parts.
