Problems solved by technology

At present, the production technology and manpower input cost of VCM mobile phone camera module is relatively high, and the thickness of solder in the conventional SMT production line depends on the thickness of the steel mesh and the parameters of the solder paste printing equipment. The deviation of the solder thickness of the empty pad can only be controlled within 40um, while for For flexible circuit boards with small volume and irregular shape, due to the inconsistent shape and size of empty pads, there are many defects such as large deviation range of solder thickness of empty pads, uneven solder thickness, high production difficulty, and low production efficiency. Unable to meet the needs of special customer groups

Description

technical field [0001] The invention relates to a production process of 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 current...
