A method and apparatus for sealing components of a front half camera module subassembly is described herein. The camera may be used in an automotive camera, which includes but is not limited to automotive rear-view cameras. A glue bead seal may be applied to the front half camera housing to which a camera lens may be attached. Then a glue bead seal may be applied to the other side of the front half camera housing to which a printed circuit board (PCB) is attached. As a result, the seals protect the lens inside optical surface and image sensor located between the camera lens and PCB from the outside environment. The lens inside optical surface and image sensor and PCB may be tested, calibrated, or have other assembly sequences completed outside of a clean room. Alignment of the PCB and lens inside optical surface and image sensor is also secured.
