Techniques and mechanisms for providing a reference potential with a flexible circuit device. In an embodiment, the flexible circuit device includes a first interconnect to exchange a signal and a second interconnect to exchange a reference potential that facilitates shielding of the signal. The first and second interconnects are variously coupled to a printed circuit board (PCB) via a first contact and a second contact of a hardware interface. During such coupling, a maximum height of the second interconnect from a side of the PCB at the hardware interface is greater than a maximum height of the first interconnect from the side of the PCB at the hardware interface. In another embodiment, a distance of the first contact from an end of the flexible circuit device is different than a distance of the second contact from the end of the flexible circuit device.
