Patent number: 9143664Abstract: 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.Type: GrantFiled: February 28, 2013Date of Patent: September 22, 2015Assignee: Flextronics AP, LLCInventors: Hong Wei Phoon, Giap Chye Toh, Yeow Thiam Ooi

Patent number: 9028159Abstract: A camera module with a lens barrel containing a lens, and a lens carrier that slidably receives the lens barrel. Each of the exterior surface of the lens barrel and the interior surface of the lens carrier include a seating surface formed thereon. One of the exterior surface of the lens barrel and the interior surface of the lens carrier include a plurality of protrusions for controlling the relative position of the lens barrel and the lens carrier. The other of the exterior surface of the lens barrel and the interior surface of the lens carrier include a plurality of channels that are sized and arranged so as to slidably receive the protrusions to allow for the lens barrel to be slid into the lens carrier. The channels also each include a transverse section to allow the lens barrel to be pivoted about an optical axis of the lens barrel.Type: GrantFiled: May 11, 2012Date of Patent: May 12, 2015Assignee: Nan Chang O-Film Optoelectronics Technology LtdInventors: Prebesh Pavithran, Yeow Thiam Ooi, Haw Chyn Cheng, Hung Khin Wong, Giap Chye Toh, Shun Kyo Low

Patent number: 8982267Abstract: A camera module including a particle trap. The particle trap may be disposed in the camera module and may be operable to prevent particles from obstructing an optical path defined between a lens assembly and an image sensor. The particle trap may include a particle getter to retain particles in contact with the particle trap. The camera module may be operative to move the lens assembly so as to provide focus on the image sensor for objects at various distances from the camera module. The movement of the lens assembly may be a source of particles retained by the particle trap.Type: GrantFiled: October 10, 2011Date of Patent: March 17, 2015Assignee: Flextronics AP, LLCInventors: Prebesh Pavithran, Yeow Thiam Ooi, Haw Chyn Cheng, Hung Khin Wong, Giap Chye Toh, Shun Kyo Low

Patent number: 8891007Abstract: A camera module with a vent in a housing thereof to allow for fluid communication between an interior of the camera module and an exterior of the camera module. A micro-porous membrane filter having a pore size smaller than 10 um is employed to cover the vent so as to reduce the flow of contaminants into the camera module.Type: GrantFiled: March 6, 2012Date of Patent: November 18, 2014Assignee: DigitalOptics CorporationInventors: Prebesh Pavithran, Yeow Thiam Ooi, Haw Chyn Cheng, Hung Khin Wong, Giap Chye Toh
