The entire tracking system of the ATLAS experiment will be replaced during the LHC Phase-II shutdown. A new silicon Inner Tracker (ITk) will contain five pixel layers equipped with new sensors and readout electronics capable to improve the tracking performance, cope with the high particle multiplicity and work in a high-luminosity environment. In order to standardize modules of the Inner Tracker, the idea of a common hybrid pixel module was introduced to be used in all regions of the detector. The common hybrid module assembly and testing techniques will be presented. The module construction, metrology and electrical testing results will be discussed. The work was done with the RD53A pixel modules - prototype modules towards the final ITk pixel detector.
