Abstract: The present disclosure discloses an optical module package structure and method thereof. The optical module includes a substrate, a shield, a photosensitive unit and a cover. The shield is disposed on the top of the substrate and forms a first housing space with the upper surface of the substrate. The photosensitive unit is disposed on the substrate and located in the first housing space. The shield has a light-receiving part above the photosensitive unit. At least one notch is on the outer surface of the shield. A cushion is disposed on the notch and protrudes on the upper surface of the shield. The cover is disposed on the cushion(s) and kept a constant distance to the upper surface of the shield by contacting with the cushion(s).
