The ATLAS detector requires upgrades to face the challenges of the new High Luminosity LHC, in particular the increase of pile-up interactions. The High-Granularity Timing Detector (HGTD) will be built in order to 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. The HGTD basic unit, so-called module, is made up of two 2x2 cm2 Low Gain Avalanche Detectors bump-bonded to two ASICs and glued to a flexible PCB. The modules are connected to the Peripheral Electronics Boards, surrounding the active area, via a Flexible Printed Circuit (Flex tail) that serves as interconnection for power, communication signals and HV bias. A prototype of different lengths of the flex tail for a small scale, but full chain HGTD demonstrator has been produced and tested. The tests results of both electrical and mechanical performance of the prototype are presented.
