Film coatings as electrically conductive pathways

Abstract:

This disclosure describes a portable electronic device that includes a first housing component having an exterior-facing surface and an interior-facing surface; and a second housing component cooperating with the first housing component to define an interior volume. A seal fills an interface between the first and second housing components. Electrically conductive material that forms an electrically conductive pathway extends across portions of the interior and exterior-facing surfaces of the first housing component. The electrically conductive pathway is configured to transmit and/or receive signals or power between an exterior and interior of the portable electronic device.
