Array camera module and its molded photosensitive element and electronic equipment
This creation relates to the field of camera modules, and further relates to an array camera module and its molded photosensitive element, manufacturing method and electronic equipment.
At present, most electronic products are increasingly integrating more functions. This trend makes cross-border products emerge in an endless stream. For example, mobile phones have been highly integrated from the original communication equipment to form a diversified set of communication, camera, Internet access, and navigation. , Three-dimensional functions are integrated into mobile electronic devices. However, most of the camera modules currently deployed in mobile electronic devices are single-lens camera modules. Such single-lens camera modules can no longer satisfy users in terms of image quality and effects. Application requirements.
What has appeared and is becoming more and more popular is a camera module with more than one lens, such as a dual-lens camera module. The dual-lens camera module provides a shooting method that mimics the structure of human eyes, and this dual-lens camera module is in 3D Shooting and scanning, gesture position recognition, color fidelity, fast focus, deep panoramic shooting, background blur shooting and many other aspects have better performance than single-lens camera modules. Therefore, camera modules with more than one lens are An important direction for the development of the camera module industry in the future. In the process of capturing images with the dual-lens camera module, the dual-lens camera module uses two imaging modules with spatial position differences to obtain images from two positions respectively, and then separates the two imaging modules according to the image synthesis method. After the captured images are synthesized, the final image of the multi-lens camera module is obtained. It is understandable that in this process, the resolution and shielding power of each imaging module of the multi-lens camera module The consistency of image effects such as light and color, as well as the deviation values in the three directions of horizontal, vertical, and vertical, are important indicators to measure the imaging quality of a dual-lens camera module.
However, the process of manufacturing and assembling the dual-lens camera module and the structure of the dual-lens camera module are far from guaranteeing the imaging quality of the dual-lens camera module at this stage. FIG. 1A shows a dual-lens camera module in the prior art, which includes a circuit board 10P, two lens mounts 20P, two imaging modules 30P, and a bracket 40P. Each imaging module 30P includes a motor lens element. 31P. Each of the lens holders 20P is individually located on the same side of the circuit board 10P, and each of the lens holders 20P is connected together by the circuit board 10P, and each of the motor lens elements 31P is respectively arranged on each The lens holder 20P is supported by each lens holder 20P, and the bracket 40P is wrapped around the outside of each motor lens element 31P. In the prior art dual-lens camera module shown in FIG. 1B, the lens holder 20P may also be an integrated structure, that is, each of the motor lens elements 31P may be arranged on a different part of the lens holder 20P. Location. It is understandable that, from the perspective of the assembly process of the dual-lens camera module in the prior art, each of the lens holders 20P is individually mounted on the circuit board 10P, which will cause each of the The size, position, etc. between the lens holders 20P are difficult to control, so that the consistency of the size, position and other parameters between each of the dual-lens camera module brackets is poor. From the structure of the dual-lens camera module in the prior art, in the example of FIG. 1A, each lens holder 20P is independent, and each lens holder 20P is connected only through the circuit board 10P Since the circuit board 10P usually uses a PCB circuit board, the circuit board 10P itself is relatively soft and easily deformed. At this time, the overall rigidity of the dual-lens camera module is difficult to ensure. When the dual-lens camera module is In the use process after the assembly is completed, such a structure is likely to cause the relative size of the various components of the imaging module 30P, such as the motor lens element 31P, to be unstable, and the position tolerance is large, and each of the imaging components The optical axis of the module 30P is prone to deviate from the preset position and other problems. Once any of these situations occurs, the imaging quality of the dual-lens camera module, such as image synthesis, and other final imaging effects will be irrelevant. Control factors or greater adverse effects. In addition, the bracket is wrapped around each of the motor lens elements 31P 40P, and it is necessary to fill glue between the motor lens element 31P and the bracket 40P, which causes the size of the dual-lens camera module to be further increased.
In addition, the assembly of the multi-lens camera module is based on the traditional COB (Chip On Board) process. The circuit board 10P usually has protruding circuit devices 11P, and a photosensitive chip 12P is mounted on the circuit board. The photosensitive chip 12P is usually connected to the circuit board 10P through a gold wire 121P, and the gold wire 121P usually protrudes in an arc shape from the main body of the circuit board. Therefore, these protruding circuit devices 11P and The gold wire 121P also brings some disadvantages to the assembly of the camera module.
The circuit device 11P and the gold wire 21P are directly exposed on the surface of the circuit board 10P. Therefore, in the subsequent assembly process, such as pasting the lens holder 20P, welding the motor lens assembly 31P, etc., it is inevitable The solder resist, dust, etc. during soldering are likely to adhere to the circuit device 11P, and the circuit device 11P and the photosensitive chip 12P are located in a space that communicates with each other. Therefore, dust and contaminants can easily affect the With regard to the photosensitive chip 12P, such an influence may cause defects such as stains and black spots in the assembled camera module, which reduces the product yield.
Secondly, the lens holder 20P is located outside the circuit device 11P, so when installing the lens holder 20P and the circuit board 10P, it is necessary to reserve a certain amount between the lens holder 20P and the circuit device 11P. It is necessary to reserve a safe distance in the horizontal direction and the upward direction, which increases the demand for the thickness of the camera module to a certain extent, making it difficult to reduce the thickness.
In addition, for the molding of multiple cameras compared to the molding of a single camera, it involves the coordination of multiple camera modules. The optical axis of multiple lenses is required to be consistent, and the optical axis of multiple lenses based on the traditional COB process Consistency is more difficult to guarantee. In addition, the multi-camera module has a larger overall volume and is more sensitive to the strength and flatness of the circuit board, so the thickness of the circuit board is larger.
