                CAH01MP

                function:
                Close loop autofocus
                pixels:
                16M/12M
                Compared with the old products, what are the improvements(Structure, material, technology, process, performance and use function)
                With the increasing mobile phone camera pixel camera, auto focus motor dynamic axis tilt angle requirements increasingly strict, consider upgrading the camera autofocus motor can meet the high pixel application, the new products of high pixel camera autofocus motor has the following improvement:
                  Old products new product utility
                material quality / / /
                structure Open Loop Hall sensor Can feedback position, form closed loop, focus more accurate With small gesture, PDAF and other control software, the focusing effect can be achieved Dual camera
                design Fixed magnet and movable coil In addition to the fixed magnet and the active coil, the design and Simulation of the magnet and the hall are also needed. In addition, the design analysis of resonance suppression is also necessary Closed-loop control can be performed without generating vibration problems
                Technology Base and Yoke are fixed with glue Base and Yoke use electric welding fixation Increasing bonding strength and mass production
                performance Postural difference≦50um Postural difference≦8um The module is easy to control and adjust
                Use function Open-Loop Poor focus accuracy Close-Loop The coke has good accuracy and fast reaction speed PDAF With the control software, the focusing effect can be achieved Dual camera
