Since two first copper layers 10 and two first protective film layers 9 are arranged on both sides of the soft board tail 6, the hardness of the soft board tail 6 is improved. The first copper layer 10, the first protective film The layer 9 and the tail part 6 of the soft board constitute the above-mentioned tail part rigid board 3 .

Based on a similar principle, a second copper layer 7 and a second protective film layer 8 are respectively arranged on the upper and lower sides of the soft board head 5 in sequence. The second protective film layer 8 of the present invention can be a PI film, or It may be ink or other circuit board protection materials known to those skilled in the art.

Of course, for those skilled in the art, the electromagnetic shielding film 11 needs to be grounded to play the role of electromagnetic shielding. For this, grooves can be provided on the surface of the flexible board connecting portion 2 to expose its internal circuit. When pasting the electromagnetic shielding film 11 , the electromagnetic shielding film 11 can be electrically connected with the circuit at the groove position of the flexible board connecting portion 2 by hot pressing.

Due to the small size of the camera module, based on the placement error of the electromagnetic shielding film 11, when mounting, ensure that there is a second gap between the end of the electromagnetic shielding film 11 adjacent to the end of the hard board 3 at the tail and the edge of the hard board 3 at the tail.
