Abstract
An optical module includes a lens housing and a substrate having a base and a sidewall. An image sensor is mounted to the base. The sidewall includes a joint surface and the lens housing includes a mounting surface. The mounting surface of the lens housing is bonded to the joint surface of the substrate thus mounting the lens housing to the sidewall. To minimize the overall width of the optical module and to maximize the strength of the bond between the lens housing and the substrate, the mounting surface of the lens housing is formed with a locking feature. The locking feature includes a horizontal surface bonded to the joint surface and a vertical surface bonded to an interior surface of the sidewall.
