Abstract: Embodiments of the present disclosure relate to an electronic module that is structured to be incorporated into a small form factor electronic device. The electronic module includes a substrate, an active component and a passive component. The substrate includes a first surface and a second surface that is opposite the first surface. The second surface of the substrate includes a recessed area that extends through a portion of the substrate towards the first surface of the substrate. The active component is placed on the first surface of the substrate and the passive component is located in the recessed area of the second surface of the substrate.

Abstract: A stabilization actuation assembly includes a lens barrel, a magnetic assembly, one or more stabilizing coils, an outer shell, and a piece of ferromagnetic material. The lens barrel is configured to carry a lens that is positioned along an optical axis. The magnetic assembly includes a plurality of magnets that produce a magnetic field. The one or more stabilizing coils are coupled to a printed circuit board below the plurality of magnets. The outer shell includes an aperture through which the lens barrel can actuate. The piece of ferromagnetic material is coupled to a surface of the outer shell and is positioned to augment the magnetic field. A current supplied to the one or more stabilizing coils interacts with the augmented magnetic field to cause the magnetic assembly together with the lens barrel to translate in a direction perpendicular to the optical axis.

Abstract: Embodiments of the present disclosure further relate to a camera device assembled such that to reduce (and in some cases minimize) auto-focusing actuation power when the camera device operates in a macro mode. The camera device includes an image sensor and a lens assembly in an optical series with the image sensor. During manufacturing of the camera device, the lens assembly is assembled within the camera device to have an optical axis substantially parallel to gravity and positioned to have an offset along the optical axis. The offset is determined during manufacturing of the camera device such that, when the camera device is in the macro mode, the lens assembly is positioned at a neutral position relative to the image sensor without actuation applied to the lens assembly.
