Abstract
The present disclosure relates to a camera module and a photosensitive assembly thereof. The photosensitive assembly includes a circuit board, a photosensitive chip and a packaging body. The photosensitive chip is connected to the circuit board, and includes a photosensitive region and a non-photosensitive region surrounding the photosensitive region. The packaging body is formed on the circuit board and a portion of the non-photosensitive region of the photosensitive chip. The packaging body includes a top surface away from the photosensitive chip and an inner side surface connecting the top surface to the non-photosensitive region. A portion of the inner side surface adjacent to the top surface is a cambered surface, and the cambered surface has a larger surface area than an inclined plane, thus the cambered surface can carry more adhesive. In this way, it is possible to effectively prevent the adhesive from flowing to the photosensitive region of the photosensitive chip.
