The High Energy Cosmic Radiation Detection (HERD) facility is a dedicated particle astrophysics experiment planned to be installed on China's Space Station. The Silicon Charge Detector (SCD), one of the sub-detectors of HERD, is designed to measure the charge of cosmic-ray nuclei with atomic numbers from Z = 1 to 28. The full-scale SCD detector module has been successfully developed for the first time. This paper presents the assembly of the detector module, as well as its performance evaluated through laser and beam tests.
