In addition, if it is determined that the camera module is defective through the good quality inspection process, the flexible circuit board attached to the camera module may be discarded.

In order to prevent this, a flexible circuit board is detached from a camera module determined to be defective and reused, but there is a problem that labor and equipment are required to perform it, resulting in poor production efficiency.

In addition, the flexible circuit board attached to the camera module is formed of a flexible material and arranged in a bent state in a camera module inspection socket to be inspected. Such a method has a problem that the connection between the flexible circuit board and the connector is not easy and the inspection is not performed due to the contact failure.

The applicant of the present invention has disclosed a Korean patent application No. 10-1639176 'Socket for OIS inspection of camera module', which can inspect whether the camera module is good or not by inspecting AF and OIS functions of the camera module stably.

However, this is applicable to the case where the connecting pads are formed so as to face opposite sides of the camera module, and it is not applicable when the connecting pads are formed on side surfaces contacting each other at 90 degrees like the camera module in recent years.

Therefore, when the pin blocks on both sides of the power supply unit are transferred to the connecting pad side, the pin block is brought into contact with only one connecting pad, so that only one connecting pad is inspected and then the other connecting pad is inspected by rotating the camera module. have.
