Abstract

A camera module comprises a substrate, an image sensing chip and a plurality of conductive leads, wherein the substrate comprises a first PCB (printed circuit board), a double-sided FPC (flexible printed circuit board) and a second PCB which are laminated sequentially to form a circuit board with a multi-layer structure, and sufficient wiring space is guaranteed accordingly; a plurality of first welding pads are arranged on an exposed upper surface of the double-sided FPCB; a plurality of second welding pads are arranged on the upper surface of the image sensing chip; one end of each conductive lead is connected with one first welding pad, and the other end is connected with one corresponding second welding pad, so that the image sensing chip is electrically connected with the substrate; further, a first through hole is formed in the first PCB, and the image sensing chip is arranged in the through hole. Therefore, the total height after the image sensing chip is assembled with the substrate is smaller than the height sum of the image sensing chip and the flexible substrate, the height of the camera module can be reduced effectively, and the development requirement for light, thin, short and small tendency day by day can be met.

Description

technical field [0001] The invention relates to the technical field of camera equipment, in particular to a camera module. Background technique [0002] With the continuous development of technology, the camera module not only needs to meet higher camera functions, but also tends to be thinner and shorter. The thinness and shortness of the camera module are one of the important factors affecting the lightness and thinness of mobile terminal camera equipment such as mobile phones. Therefore, it is particularly important to improve the structure of the camera module and develop in a direction that is conducive to the lightness and thinness of mobile terminal camera equipment such as mobile phones. [0003] A traditional camera module is usually composed of a lens, a lens support component, a sensor photosensitive device and a circuit board. The total height of the camera module = the optical length of the lens (TTL, Total Track Length) + the height of the sensor photosensitiv...
