Abstract：X-ray fluorescence spectrometer is an instrument for quantitative analysis of elements in metallurgical industry laboratory, and it has been widely used in domestic iron and steel enterprises. The decoupling capacitor breakdown fault of circuit board reset circuit for rotary table control of 12-position sample box was introduced using ARL9900 X-ray fluorescence spectrometer as an example. This phenomenon was analyzed and the treatment methods of this instrument were discussed. Moreover, the encapsulated transformer damage on power interface circuit board of tube generator as well as check and treatment methods were also introduced. The analysis and treatments of two types of typical circuit board chip faults provided a new idea for the correcting of chip failures for precise instruments in laboratory. It was helpful to rapidly resume production and save spare parts cost.
