<jats:p>The High Granularity Timing Detector for the ATLAS upgrade is under construction to meet the challenges of the HL-LHC. In order to connect a module, the basic detector element, to the surrounding peripheral electronic board, a flexible printed circuit (FPC) is used as an interconnection for data transmission and power distribution. An identical design for all FPCs is required except for their length, depending on the module position on the detector active area. The design and qualification of a preliminary FPC version, manufactured in 13 different lengths (from 28.5 to 73.2 cm), are presented.</jats:p>
