Embodiments relate to systems and methods for forming a circuit assembly for an electronic device. The circuit assembly may include a substrate and a group of surface-mounted electronic components disposed on a surface of the substrate. An electrical connector may be disposed on the surface and may be configured to receive an electrical connection from a separate electrical component or assembly. A molded layer may be formed over at least a portion of the surface fully encapsulating the group of surface-mounted electronic components and partially encapsulating the electrical connector.
