Circuit board assembly with photosensitive element mounted to back side of circuit board

Abstract

A camera module is provided, including a circuit board, a photosensitive element, an optical lens, and a filter element. The circuit board includes a substrate having a substrate front surface, a substrate back surface, and a substrate channel. The substrate front surface and the substrate back surface correspond to each other, and the substrate channel extends from the substrate front surface to the substrate back surface. The photosensitive element has a photosensitive area and a non-photosensitive area surrounding the photosensitive area. A first part of the non-photosensitive area is mounted on the back surface substrate. The photosensitive element and the substrate are conductively connected. The photosensitive area and a second part of the non-photosensitive area correspond to the substrate channel. The optical lens is held in a photosensitive path of the photosensitive element. The filter element is directly mounted on the substrate front surface of the substrate.
