Abstract	The ATLAS ITk Pixel system requires large-scale flex circuits for low-voltage power, high-voltage sensor bias, and command/data transmission due to tight space constraints. This reports will focus on the design and production of the services that runs from the modules and the first patch panel of the ITk Pixel Outer Barrel. The results from the quality control tests on the pre-production (10% of what is needed to equip the final detector) will be discussed. In this report we also describe the procedure developed for the complex 3D bending needed to accommodate the routing and to respect the mechanical envelope.
