A method for manufacturing a printed circuit board includes forming a through hole in an insulating layer of the printed circuit board, filling the through hole by plating to form a plating layer on the insulating layer, and removing the plating layer from the insulating layer; and forming a circuit pattern on the insulating layer.

Printed circuit board

Provided are an auto focus (AF) locking unit and a photo-graphing apparatus including the AF locking unit. In particular, the AF locking unit supports a lens group barrel holder that is descended by a movement of a front barrel in an optical axis direction by using a locking lever provided with an elastic force, and the photographing apparatus includes the AF locking unit. According to an embodiment, the AF locking unit supports the lens group barrel holder including lenses in the optical axis direction by using a driving force transmitted from a motor in correspondence to movements of a cam barrel and a front barrel, and the photographing apparatus includes the AF locking unit.

A lens assembly and an electronic device are provided. The lens assembly and/or the electronic device includes a lens barrel, a housing configured to accommodate the lens barrel on one surface of the housing, and an image sensor assembly mounted to the other surface of the housing, the image sensor being configured to rotate around an optical axis of the lens barrel. The image sensor assembly includes a ring-shaped rotation member facing the other surface of the housing, and a plurality of balls interposed between the rotation member and the other surface of the housing. The rotation member rotates on a plane perpendicular to the optical axis.

Position sensor assemblies having compact structures and capable of precisely sensing a position change, and optical devices including the same are disclosed. A position sensor assembly is provided that includes: a sensing unit that outputs a signal varying as a magnetic force varies; and a magnet spaced apart from the sensing unit and i movably disposed with respect to the sensing unit, and comprising protrusion units of opposite polarities that protrude from each end portion of the magnet in one surface of the magnet toward the sensing unit.

Position sensor assembly and optical device including the same

A lens barrel and a photographing apparatus comprising the lens barrel include: a lens module that comprises at least one lens and moves along an optical axis of the at least one lens; a shake correction module arranged near the lens module; at least one fixing member that is disposed between the lens module and the shake correction module and fixes the shake correction module in response to being pressed by the lens module; a frame on which the at least one fixing member is installed; and at least one elastic member that elastically mounts the at least one fixing member on the frame.

Lens barrel and photographing apparatus comprising the same

An optical device includes an optical element through which light is transmitted, a frame that supports the optical element, magnets in the frame around the optical element, a base unit that movably supports the frame, a cover unit to cover the magnets, and magnetic force generating units in the cover unit in positions corresponding to the magnets and that generate magnetic force when an electrical signal is applied.
