A voice coil motor includes a housing having a cavity; a movable assembly received in the cavity; a fixing assembly configured outside of the movable assembly; and a first spring plate and a second spring plate configured at an upper surface and a lower surface of the movable assembly respectively. The fixing assembly comprises at least two magnetic elements connected with the first spring plate and a spacer member configured on the second spring plate to connect the second spring plate to the magnetic elements or the housing. The voice coil motor is served as an actuator of electronic products such as digital cameras, mobile phones, and digital cameras, which has thin thickness, good performance and strong applicability.

An assembly method of a SMA assembly, includes disposing a lens holder unit on a SMA unit, the lens holder unit being provided with a first spring, a lens holder and a coil that are mounted on the first spring, with the first spring pressed against a mounting surface of the SMA unit; and bonding the first spring of the lens holder unit with the mounting surface of the SMA unit. The assembly process is simplified, the coating and soldering space become big to facilitate the bonding process, and the joining force between the SMA unit and the lens holder unit is enhanced.

Assembly methods of a SMA assembly and an OIS device

A method for mounting a head stack assembly (HSA) circuit assembly is disclosed. A flexible circuit substrate may be coupled to a stiffener. The stiffener may be a metal, such as aluminum, or some other stiff and durable material. The flexible circuit substrate may be made of an organic material and may have a series of electronic leads embedded in the flexible circuit substrate. The flexible substrate may be coupled to the stiffener by an adhesive or laminated onto the stiffener. The stiffener may be mounted onto the actuator arm by soldering or by laser welding.
