[0003] Since the FPC is thin and soft, the end portion is prone to curling. Therefore, in the Fpc horizontal production process, the FPC is usually taped to a guiding jig, such as a rigid substrate, and then the Fpc guiding fixture is fixed. Placed on the horizontal transfer device, the FPC can be leveled through the horizontal transfer device to complete the horizontal production process of the FPC, thereby preventing the FPC end from being caught in the interface or gap of the horizontal transfer device due to curling, and the product is scrapped. However, if the FPC is completed by the above method, the 5 丨 guiding fixture and tape should be peeled off from the FPC. During the stripping process, tFPC is easily crushed or broken, and there may be incomplete removal of the tape on the Fpc surface, which causes residual glue on the surface of the FPC, resulting in a decrease in product yield.

Preferably, the height of the guiding portion 120 is greater than or equal to the sum of the thicknesses of the carrier plate 1U and the cover plate 112, so that the second side surface 1123 of the cover plate 112 can completely abut The first side wall 121. In this embodiment, the height of the bow guide 12G is greater than the sum of the thickness of the carrier plate and the cover 112. 097112272 Form No. A0101 Page 10 of 21 1003312606-0 1354514 August 25, 100 The shuttle is replacing the page, and the circuit can be first placed on the bearing surface 1111 of the carrier board 111 by using the circuit board guiding fixture provided in this embodiment, so that the positioning member 1115 passes through the positioning hole of the circuit board. The clamping surface 1121 of the cover 112 is opposite to the first side wall 121 of the guiding portion 120 toward the third side 1123 of the circuit board, and the positioning member 1115 is inserted into the through hole 1127 of the cover 112, thereby placing the cover 112 On the circuit board, the third side surface 1123 is in contact with the first side wall 121. Thus, the circuit board acts on the mutual attraction between the first magnetic body 1114 of the carrier plate 111 and the second magnetic body 1125 of the cover plate 112. The bottom plate can be clamped to the carrier plate 111 and the cover plate 112. And finally, the horizontal conveying device is driven by the guiding portion 120. Since the cover plate 112 abuts against the guiding portion 120, the cover plate 112 does not move relative to the carrier plate 111, ensuring that the circuit board is in the process of transmission. Flatness and Stability [0022] The width of the board guiding jig is 60 mm to 250 mm. Accordingly, the height of the guiding portion 120 may be less than or equal to 2 ram. The carrier plate 111 may have a width of 20 mm to 60 mm.
