The event plane detector (EPD), installed in the Solenoid Tracker at theRelativistic Heavy-Ion Collider located at the Brookhaven National Laboratoryis a plastic scintillator-based device that measures the reaction centralityand event plane in the forward region of the relativistic heavy-ion collisions.We used silicon photomultiplier (SiPM) arrays to detect the photons produced inthe scintillator via the fiber connection. Signals from the SiPM arrays wereamplified by the front-end electronic (FEE) board, and sent to theanalog-to-digital converter (ADC) boards for further processing via thereceiver(RX) board. The full EPD system consisted of 24 super-sectors (SSs);each SS was equipped with two SiPM boards, two FEE boards and two RX boards,and they corresponded to 744 readout channels. All these boards were massproduced at the University of Science and Technology of China, with a dedicatedquality assurance (QA) procedures applied to identify any problems beforedeployment. This article describes the details of the QA method and the relatedtest system. The QA test results are presented along with the discussions.
