Description of the Invention: [Technical Field] The present invention relates to a flexible printed circuit board, and more particularly to an electrostatic discharge (ESD) protection that utilizes the original structural design of a circuit board to direct static electricity to a ground end of a circuit board. structure. [Prior Art] Because ESD (Electro Static Discharge) is easy to cause damage to electronic devices, most electronic devices are designed with electrostatic discharge protection circuits to eliminate static electricity to protect electronic devices and electronic components from static electricity. The high pressure generated is destroyed. However, as the electronic device becomes more and more miniaturized, the internal space of the electronic device is continuously compressed, and the space available for the circuit board is reduced. The design difficulty of the electrostatic discharge protection circuit is relatively high. Please refer to the structural diagram of a conventional flexible printed circuit board shown in FIG. 1 and FIG. 2 on a liquid crystal panel. The flexible printed circuit board 10 is generally made of AAC (Anisotropic Conductive Film). The bonding method is electrically connected to the liquid crystal panel 20, and the circuit 15 of the flexible printed circuit board 1 and the circuit 22 connected to the integrated circuit 21 of the liquid crystal panel 20 are electrically connected to each other. The flexible printed circuit board 10 has a circuit board body 11 having a neck portion 12 having a width narrower than the visibility of the circuit board body 11 due to the necessity of the flexible printed circuit board 1 The neck portion 12 is folded back rearwardly. Therefore, a hollow portion 13 is provided in the neck portion 12 to improve the flexibility to facilitate folding. However, since the provision of the venting portion 13 also causes the strength of the neck portion 4 201036498 12 to decrease, it is easy to be broken by the external force and the neck portion a is broken, so that the circuit 15 is damaged. Therefore, a periphery of the hollow portion 13 of the neck portion 12 is provided. The coiled copper foil 14 serves as a reinforcing structure. Referring to the third figure, the flexible printed circuit board 1 further includes a protective layer 16 having a body 161 and a neck 162 having a width narrower than the body 161. The main body 161, the neck portion 162 and the transparent portion 163 have a shape corresponding to the circuit board body 11, the neck portion 12 and the transparent portion 13 of the flexible printed circuit board 10, and the insulation is made by the insulation. The protective layer 16 is attached to the surface of the circuit board body 颈部 and the neck 12 to protect the circuit 15 or the electronic component (not shown). At the same time, the protective layer 16 can cover the copper foil around the permeable portion 13. u. However, although the copper case 14 has the protective layer 16', but since the copper foil 14 is very close to the transparent portion, the static electrode is easily broken by the transparent portion 13 into the circuit through the steel 羯=into the circuit 15, 22'. The integrated circuit 21 of the liquid crystal panel 20 thus causes damage to the liquid crystal panel 20 or the integrated circuit 21. You must ask for the month. In the case where the space of the neck 12 is allowed, the circuit & 15 can be kept away from the copper foil 14'. However, in recent years, the electronic product pursues volume and the trend is soft. As the volume of the printed circuit board 10 shrinks, the difficulty in circuit layout is also increasing. [Invention] In view of the lack of the prior art, the object of the present invention is to provide a flexible printed circuit board, which utilizes the original structure of the circuit board to guide static electricity from the ground end of the inflow board to avoid static current flowing to the circuit board.
