The invention discloses an image sensor module for a shooting device and an assembly method thereof. The image sensor module for the shooting device comprises a lens assembly containing a lens group, a mainboard, an image sensor chip and a keyset, wherein the mainboard is connected with the image sensor chip through the keyset, and the mainboard and the image sensor chip are electrically communicated through the keyset; the sum of the thickness of the keyset and the thickness of the sensor chip is equal to the focal length of the lens group; the mainboard is provided with a first contact group corresponding to the pin of the image sensor chip; the keyset is provided with a second contact group corresponding to the pin of the image sensor chip; grooves are formed at the positions corresponding to each second contact at the periphery of the keyset; and the inner surfaces of the grooves and regions around the grooves, of the surfaces are respectively provided with an electric conduction plating layer so as to form a third contact group. According to the invention, the technical problems of complicated structure, high cost and poor focusing effect of a focusing device are solved.
Description
technical field [0001] The present invention relates to an image sensor module used in photographing equipment, and more specifically relates to an image sensor module used in photographing mobile phones, digital cameras, video cameras, camera heads, PC CAMERA and other similar products. Background technique [0002] Due to the comprehensive reasons such as the size error and assembly error of the components of the lens module of the digital camera and other shooting equipment, the lens thickness, the lens refractive index error, and the air gap, the focus position changes. Therefore, in the digital camera lens module assembly, manufacturing and maintenance process Among them, there is a focusing process, which is to adjust the distance between the lens group and the sensor, so that the light signal of the incident light incident on the sensor through the lens group can be optimized, so that the image is the clearest. [0003] The traditional method of using an optical tab...
