Abstract: A camera module with sticky epoxy and method for dislodging particles from a corresponding IR filter. Particles, formed during manufacture or use of the camera, may accumulate in the camera (e.g., on an infrared filter) causing blemishes in camera images. A sticky epoxy with characteristics for attracting and capturing particles is located in the camera. The epoxy may be located in a gap between a substrate and an outside edge of an infrared filter coupled to the substrate. The epoxy and the gap may surround the infrared filter and the epoxy may also be located on other surfaces of the camera. A process for loosening particles from the infrared filter includes driving an actuator that moves the substrate/infrared filter assembly (perhaps striking a base assembly) to loosen the particles from the infrared filter such that the particles are moved to, and trapped by, the epoxy.
