Abstract
A method for manufacturing camera modules for use in portable electronic devices, such as mobile phones, is provided. More specifically, in camera modules utilizing lens motion type auto focus actuation, permanent magnets associated with voice coil motors utilized in the auto focus system, generate magnetic flux that can interfere with the process of bonding image sensors to camera modules if the permanent magnets of different voice coil motors are positioned too closely. Incorporating a magnetic shield into the manufacturing process to restrain or control the magnetic flux generated by the permanent magnets permits voice coil motors camera modules to be positioned closer together during the manufacturing process. This increases manufacturing throughput and reduces cost.
