To meet the challenges of the High Luminosity-LHC, especially the increase of pile-up interactions, the ATLAS detector needs to be upgraded. One of the foreseen upgrades consists of the installation of the High-Granularity Timing Detector (HGTD). The HGTD will mitigate the effects of pile-up in the ATLAS forward region, providing time information with a resolution of about 30 ps per track. The active area consists of 2-double-sided disks per end-cap. Two 2x2 cm2 Low Gain Avalanche Detectors bump-bonded to two ASICs and wire bonded to a flexible PCB form the HGTD basic unit, the so-called module. 8032 modules have to be built in total. During the HGTD R&D phase, module prototypes are assembled and tested in order to optimize the procedures and be integrated for system level tests in the HGTD demonstrator. The module assembly procedure in Mainz and the results of the very first assemblies are presented.
