The image sensing chip and at least one auxiliary chip are packaged by a plastic package material to form a chip package body, the circuit faces of the image sensing chip and at least one auxiliary chip face the same direction. The image sensing chip comprises an image sensing unit and package glass arranged above the incident face of the image sensing unit, a light through hole corresponding to the package glass is formed in the front side of the chip package body, a wire re-arrangement graph electrically connected with the welding pad of the image sensing chip and the welding pads of at least one auxiliary chip is formed on the back side of the chip package body, and multiple convex points are formed on the wire re-arrangement graph. The lens bracket is installed on the front side of the chip package body, and a lens group is fixed to the lens bracket. The reliability of the image sensor module is improved, and the wire arrangement difficulty is reduced.

Description

technical field [0001] The invention relates to the field of sensors, in particular to an image sensor module and a manufacturing method thereof. Background technique [0002] An image sensor chip is a semiconductor device that senses external light and converts it into electrical signals. After the image sensor chip is manufactured, a series of packaging processes are first performed on the image sensor chip, and then the mirror mount bracket and the lens are installed to form an image sensor module. Image sensor modules are mainly used in electronic devices such as smartphones, tablet computers, digital cameras, car driving recorders, and children's toys. [0003] The existing image sensor chip packaging method is mainly COB (Chip On Board) packaging, the bare chip is attached to the interconnection substrate with conductive or non-conductive adhesive, and then wire bonding is performed to realize its electrical connection. The image sensor packaging method in the prior ...
