Sensing device and image sensor module thereof

摘要

An image sensor module is installed in a sensing device, and is used to detect a reflected light of an object. The image sensor module includes a carrier, a light sensing element, and a package body. The light sensing element is disposed on a substrate. The carrier is disposed on the substrate in the sensing device. The light sensing element is installed in the carrier, and is electrically connected with the substrate via multiple solder balls. The package body is installed on the carrier, and has a reflecting and diverting element, which is located between the light sensing element and the object and is used for reflecting reflected light of the object and diverting the reflected light towards a receiving direction of the light sensing element. The light sensing element receives the reflected light and generates a corresponding sensing signal.
