Description

Circuit board alignment device for product test socket {CIRCUIT BOARD ALIGNING APPARATUS FOR PRODUCT TEST SOCKET}

The present invention relates to a circuit board alignment device for a product test socket. In particular, it is applied to a product test socket for testing ultra-small products such as camera modules to prevent test defects by aligning and fixing the flexible circuit board connected to the camera module to a designated position. A circuit board alignment device for a product test socket that prevents or inhibits.

In general, small camera modules are widely used in mobile phones, automobiles, small electronic products, industrial surveillance devices, and home surveillance devices.

Since small camera modules have a very small volume and a wide variety of components are densely placed inside, the products are fully tested for normal operation and performance before shipping.

The small camera module includes a main body, a flexible circuit board connected to the main body, and terminals placed on the flexible circuit board. The terminals on the flexible circuit board must be placed in designated locations so that the terminals formed on the test unit are on the flexible circuit board. It can be accurately connected to the terminal.

In the prior art, in order to place the terminals of the flexible circuit board of a small camera module at designated positions, a plurality of guide members are arranged around the flexible circuit board, and can be inserted into the flexible circuit board in the space formed by the guide members. A sufficient gap is formed between the guide member and the flexible circuit board.

If the gap formed between the guide member and the flexible circuit board is large, the alignment error of the flexible circuit board is large, increasing the possibility of poor connection between terminals, and if the gap formed between the guide member and the flexible circuit board is small. There is a problem in that it is difficult to accurately insert the flexible circuit board into the space formed by the guide member, or a part of the flexible circuit board is damaged.
