    Abstract: Provided are flexible interconnect circuit assemblies and methods of fabricating thereof. In some examples, a flexible interconnect circuit comprises multiple circuit portions, which are monolithically integrated. During the fabrication, some of these circuit portions are folded relative to other portions, forming a stack in each fold. For example, the initial orientation of these portions can be selected such that smaller sheets can be used for circuit fabrication. The portions are then unfolded into the final design configuration. In some examples, the assembly also comprises a bonding film and a temporary support film attached to the bonding film such that the two circuit portions at least partially overlap with the bonding film and are positioned between the bonding film and temporary support film. In some examples, at least some circuit portions extend past the boundary of the bonding film and are coupled to connectors.

    Abstract: Provided are flexible interconnect circuits comprising signal circuit elements. For example, a signal circuit element can be formed from the same metal sheet as a signal trace, thereby being monolithic with the signal circuit element. This integration of signal circuit elements into a flexible interconnect circuit reduces the number of additional operations and components (e.g., attaching external circuit elements). In some examples, a flexible interconnect circuit is used in a battery pack for interconnecting batteries while providing external terminals on the same side of the pack. Specifically, a flexible interconnect circuit comprises an interconnecting conductive layer (for connecting to batteries) and a return conductive layer, both extending between the first and second circuit edges. Each of these conductive layers comprises a corresponding external terminal at the first edge, while these layers are interconnected at the second edge. Otherwise, these layers are isolated from each other between the circuit edges.
