• and
• a blocking element which is provided at a position where said packaging body and said photosensitive element are in contact with each other and outside said photosensitive area of said photosensitive element to prevent said packaging body from extending to said photosensitive area of said photosensitive element.

A photosensitive assembly for assembling at least a camera module comprising at least one lens, comprising:

• at least one window circuit board comprising a board body which has at least a window formed therein and a circuit provided outside said window in said board body, wherein said window circuit board has at least one reinforcing hole formed therein;
• at least one photosensitive element installed in said window and electrically connected with said window circuit board through one or more electrical connectors, so that an overall thickness of said window circuit board and said photosensitive element is smaller than a thickness of said window circuit board plus a thickness of said photosensitive element;
• wherein said photosensitive element forms a photosensitive area and a non-photosensitive area surrounding said photosensitive element on a top side thereof;
• and
• at least one packaging body provided around said photosensitive area of said photosensitive element above said window circuit board adapted for installing the lens thereon to form the camera module, wherein at least a portion of said non-photosensitive area of said photosensitive element, at least a portion of top side of said window circuit board and said electrical connectors are integrally packaged by said packaging body to define a light window within said packaging body, wherein said light window is aligned with said window of said window circuit board to define a light path for said photosensitive area of said photosensitive element adapted for aligning with the lens installed on said packaging body, wherein said packaging body has at least one inserting portion extended into said reinforcing hole of said window circuit board to further engage said packaging body with said window circuit board so as to reinforce a structural strength of said window circuit board.
