Embodiment 1
[0032] figure 1 The flow chart of the method for preventing electrostatic breakdown provided by Embodiment 1 of the present invention, such as figure 1 As shown, the method includes:
[0033] 101: When forming the conductive pattern of the substrate, connect the metal wire forming the conductive pattern to the closed conductive ring located in the peripheral area of the substrate;
[0034] 102: When static electricity is generated on the metal wire, guide the static electricity to the closed conductive ring.
[0035] According to the characteristic that static electricity tends to be distributed on the outer edge of the conductor, the embodiment of the present invention proposes a method of connecting the metal wire forming the conductive pattern to the closed conductive ring located on the periphery of the substrate when forming the conductive pattern of the substrate. In the process of manufacturing the substrate, if static electricity is generated on the metal wire, the...
