Camera module assembly

A camera unit assembly of the present invention improves the welding fixing efficiency and quality of a lens holder module and a circuit board module by providing a partially closed through-hole in a mounting portion of the lens holder module, in which the through-hole can accommodate a solder ball, and welding energy can be introduced into the through-hole, thereby improving the welding fixing efficiency and quality of the lens holder module and the circuit board module. Thus, the solder balls are melted and at least partially flow from the bottoms of the through holes to the pads of the circuit board. 本发明一种相机单元组件，它通过在镜头固定器模块的安装部分提供部分闭塞的通孔来提高镜头固定器模块和电路板模块的焊接固定效率和质量，其中，该通孔可以容纳焊球，焊接能量可传入该通孔，从而使该焊球熔化并至少部分地从通孔底部流到该电路板的焊盘上。
