To meet the challenges of the High Luminosity Large Hadron Collider (HL-LHC), especially the increase of pile-up interactions, the ATLAS detector will need to be upgraded. One of the foreseen upgrades will be the installation of the High-Granularity Timing Detector (HGTD). The HGTD will mitigate the effects of pile-up in the ATLAS forward region, providing a time resolution of about 30-50 ps per track. The active area consists of 2-double-sided disks per end-cap. Two 2x2 cm* Low Gain Avalanche Detectors bump-bonded to two ASICs and glued to a flexible PCB form the HGTD basic unit, the so-called module. Multiple modules are then glued onto a support unit to form a detector unit. Each module is tested before and after being glued to a support unit. Prototype modules and detector units are being assembled at Johannes Gutenberg University Mainz in preparation for the production of around 1000 modules for the final detector over the next few years. The assembly procedure, performance and test results are presented.
