VCM mobile phone camera module

Abstract

The invention relates to a VCM mobile phone camera module. The camera comprises a lens, a voice coil motor, a base, an optical filter, an image sensor, a flexible circuit board, a bottom plate and a connector; the lens is arranged in the voice coil motor; the voice coil motor is arranged on the base; the optical filter and the image sensor are arranged between the base and the flexible circuit board; the flexible circuit board is embedded in the bottom plate; the flexible circuit board comprises a transverse section and a vertical section, a reserved area is arranged on the front face of the transverse section, six preparation bonding pads different in size are arranged in the reserved area and arranged at intervals along the inner edge of the arc-shaped edge, and a groove is formed in theposition, corresponding to the reserved area, of the back face of the transverse section. The VCM mobile phone camera module has the advantages of being high in positioning precision, capable of improving the assembling efficiency and high in performance percent of pass.

Description

technical field [0001] The invention relates to a camera module of a VCM mobile phone. Background technique [0002] With the development of camera phones to high pixel, it began to ask for auto focus function. Generally speaking, users expect autofocus in camera phones with more than 2 megapixels. However, according to the traditional method, the focus function will greatly increase the size of the circuit board and the thickness of the mobile phone. In today's era, the pursuit of short, light and thin electronic products is becoming more and more demanding. Therefore, VCM becomes the best choice for mobile phone camera module. VCM (Voice Coil Moto), commonly known as a voice coil motor or a voice coil motor, is used to adjust the position of the lens to make the camera show the clearest state. It has the advantages of small footprint on the circuit board, high reliability, and high power support. It can reduce system cost and size, and is currently widely used in automa...

AI Technical Summary

Problems solved by technology

At present, the VCM mobile phone camera module has low positioning accuracy and low assembly efficiency. For flexible circuit boards with irregular shapes, due to the different sizes of the pads, the thickness of the solder is not uniform, and solder may appear in the subsequent processing and welding process. A short circuit occurs in the overflow, which affects the pass rate of the final product performance
