Abstract:
1. A method for manufacturing camera modules, comprising: providing a plurality of image sensors on a substrate, including a first and a second image sensor that are adjacent to each other; providing a plurality of VCM modules, including a first and a second VCM module, each VCM module adapted for attachment to an image sensor and including a yoke, permanent magnets coupled with the perimeter of an inner wall of the yoke, a coil positioned radially inwardly from the permanent magnets, and an EMI shield surrounding the yoke and configured to restrict electromagnetic flux created by the coil and yoke when current is flowing in the coil; providing a plurality of removable magnetic shields, including a first and a second removable magnetic shield, each shield adapted for placement over a VCM module; placing the first removable magnetic shield over the first VCM module, thereby controlling a constant magnetic flux generated by the permanent magnets of the first VCM module; placing the second removable magnetic shield over the second VCM module, thereby controlling a constant magnetic flux generated by the permanent magnets of the second VCM module; positioning the first VCM module, with the first removable magnetic shield over the first VCM module, over the first image sensor; positioning the second VCM module, with the second removable magnetic shield over the second VCM module, over the second image sensor; positioning the first and second VCM modules with the first and second removable magnetic shields placed thereover on the substrate such that the first and second VCM modules, but not the first and second removable magnetic shields, are affixed with the first and second image sensors; moving the first and second image sensors, with the first and second VCM modules and the first and second removable magnetic shields thereon, away from each other; and removing the first and second removable magnetic shields from the first and second VCM modules.
