Abstract	As pixel channel density increases and power requirements grow, electrical services infrastructures have been challenged to keep pace. Increased levels of integration in PCBs and hybrid flex circuits have led to more complex designs with tight specifications for large currents and gigabit data transmission rates. We report on several new approaches to services integration in high-density infrastructures, designed for the ATLAS ITk pixel detector. These approaches have required design collaboration with manufacturers to realize layouts with multiple layers, exact registration, and large dimensions. Results from prototype services units show that the designs meet the stringent electrical and environmental specifications for the ITk pixel detector performance. We will also comment on design lessons learned from these collaborations.
