The High Granularity Timing Detector (HGTD) for the ATLAS upgrade is under construction to meet the challenges of the HL-LHC. The silicon detectors along with the electronics are installed in two double-sided disks per end-cap and consist of modules connected to the peripheral electronics by flexible printed circuit cables (flex tails), which serve as interconnections for power, communication signals and HV bias. Their final version has been designed and several prototypes have been produced with mechanical as well as electrical tests offering promising results so far. The results of the latest tests both in the lab and at a demonstrator with the full readout chain will be presented. Mechanical aspects towards integration in the final detector are also considered.
