Problems solved by technology
[0005] Due to the thinner and lighter requirements of mobile phones, the volume of the zoom module itself is very small. Therefore, the operation method of manually welding the pins of the voice coil motor and the flexible circuit board is not only time-consuming and laborious, but also difficult to guarantee the pass rate of the product, resulting in poor product quality. High, camera module output and yield are very limited

Embodiment 1
[0046] This embodiment provides a welding process between the flexible circuit board and the pins of the voice coil motor, which is a process for welding the pins 500 of the voice coil motor and the flexible circuit board 400 of a zoom module with a small volume such as a mobile phone. The structure of the zoom module will not be described in detail here. The voice coil motor is assembled on the base 300. The part of the pin 500 to be welded of the voice coil motor is exposed from the base 300. It is necessary to solder the exposed pin 500 to the corresponding position on the flexible circuit board. figure 1 , figure 2 with image 3 Two structures in which the pins 500 of the voice coil motor are welded to the flexible circuit board are illustrated.
[0047] The welding process of the flexible circuit board and the pins of the voice coil motor in this embodiment specifically includes the following steps:
[0048] a. Place a plurality of camera modules bonded to the flexible...

The invention provides a welding process of a flexible circuit board and a voice coil motor pin. The process comprises the steps of: a, arranging the flexible circuit board and a plurality of camera die sets adhered with a base into a clamp in advance, wherein the voice coil motor pin exposed from each camera die set base is correspondingly in contact with the welding position on the flexible circuit board; arranging the clamp to a processing station of a dispensing device, and dropping solder paste to the position corresponding to each voice coil motor pin through the dispensing device; C, moving the whole clamp dropped with the solder paste in step b to a soldering device, wherein a solder tip of the soldering device is in contact with each voice coil motor pin with the solder paste; melting the solder paste to achieve welding of each voice coil motor pin and the flexible circuit board; d, removing the clamp from the soldering device, opening the clamp, moving out the die sets, and then finishing the whole welding process. The welding process has the characteristics of being convenient to operate, high in preparation efficiency, and good in product quality.
Description
technical field [0001] The invention relates to the technical field of cell phone camera module preparation, in particular to a welding process for a flexible circuit board and a pin of a voice coil motor. Background technique [0002] As smart products become more and more popular in people's lives, taking mobile phones as an example, mobile phones are not only used as communication tools, but also gradually take on more functions, one of which is the shooting function. When pursuing the light and thin structural features of mobile phone products, it is also necessary for mobile phones to have better shooting effects, and some mobile phones are also equipped with a zoom function. [0003] The zoom function of the mobile phone camera device is realized by the voice coil motor installed in the zoom module. Its structure is to install a voice coil motor on the base of the zoom module. Board) welding connection, the flexible circuit board is powered to drive the voice coil mot...
