Recently, high-end camera modules are equipped with additional functions such as autofocusing and zooming, and these camera modules require more complicated and precise assembly processes than general camera modules.

Accordingly, in the camera module assembling process, a jig for fixing the position of the camera module to an accurate position is required, and a lot of research and development have been made on the jig.

During the assembling process of the camera module, there is a process of joining the housing and the printed circuit board. In this joining process, the camera module assembling jig is utilized to help the joining process.

In the prior art, the jig used in the manufacture of the cellular phone electronic product camera presses the substrate through the pushing device for the complete attachment of the substrate when the flexible circuit board is attached. At this time, if the force of the pushing device is excessive, the housing is deformed to cause defects.
