Manufacturing process of periscopic camera module shell

Abstract

The invention belongs to the technical field of camera modules, and particularly relates to a manufacturing process of a periscopic camera module shell, which at least comprises the following steps: etching: placing a base material subjected to coating, exposure and development treatment in an etching solution for etching treatment to obtain a substrate with a light through hole, and forming a chamfer structure on the inner side edge of the light through hole; film plating: plating an absorbing film layer on the substrate by adopting a plasma sputtering film plating process, and in the film plating process, shielding a non-film-plating region by using a jig, so that the absorbing film layers are attached to the film plating region and the chamfering structure; bending is conducted, specifically, stamping and bending operation is conducted on the coated substrate, and a shell frame is obtained; and the shell frame obtained in the third step is subjected to laser welding, and the needed shell is obtained. Compared with the prior art, light reflection of the light through hole can be reduced to the maximum extent under the dual effects of reducing the reflection area and reducing the reflectivity, so that stray light is inhibited, the thickness of the film layer is small and controllable, and the image quality and definition of the camera are improved.

Description

technical field [0001] The invention belongs to the technical field of camera modules, and in particular relates to a manufacturing process of a periscope camera module shell. Background technique [0002] At present, terminal devices with camera functions have become indispensable electronic products in people's work and life, such as smart phones and tablet computers. The increasing demand for cameras in smartphones and tablet computers makes the camera one of the important core components of smartphones and tablet computers. [0003] A periscope camera is a camera with a special structure designed for shooting distant objects. Its main characteristics are long focal length and small viewing angle. It can achieve clear shooting for long-distance targets. It usually includes camera components and reflectors. , the external natural light is reflected by the mirror and then imaged on the camera assembly. The camera assembly needs to use a housing assembly, which contains a ...

Problems solved by technology

In order to reduce the reflectivity of the light hole and internal blackening, the existing technology generally prints black through the silk screen process, but the reflectivity of the shell in the prior art is relatively high in the 400-800nm ​​light band, and generally can only reach less than or equal to 2%. , and there will be more stray light, so that the image quality and definition of the camera cannot meet people's higher and higher requirements, and affect the user experience
