| 20110043954 | ELECTROSTATIC DISCHARGE PROTECTION STRUCTURE AND ELECTRONIC DEVICE USING THE SAME - An electrostatic discharge (ESD) protection structure and an electronic device using the same are provided. The ESD protection structure includes a discharge structure and a conduction structure, wherein the discharge structure and the conduction structure respectively have a pointed end, and the pointed ends thereof are adjacent to each other. The discharge structure and the conduction structure are both disposed on a bottom side of a printed circuit board (PCB) substrate, wherein the conduction structure is connected to a ground line and the discharge structure is connected to a signal line disposed on a top side of the PCB substrate through a via. Therefore, the top side of the substrate is not required to save a layout region for disposing the ESD protection structure, and moreover an original ESD protection effect is still maintained. | 02-24-2011 |
