[0002] After the metal shrapnel is bonded to the FPC (flexible printed circuit), the flexible circuit board and the metal shrapnel form an arched structure. In order to prevent dust from entering the bonding point, an arched film needs to be covered on the side of the flexible circuit board to form a folded angle, and the folded angle can be bent to cover the other side of the circuit board.
