PCB structure for wiring of electrostatic protection device and signal test equipment

The invention discloses a PCB structure for wiring of an electrostatic protection device and signal test equipment. The GND layers are arranged in multiple layers, and corresponding hollowing processing is carried out on the orthographic projection area of the electrostatic protection device in the first GND layer, so that a first hollow area and a second hollow area contain orthographic projection areas of the signal lines on the first GND layer as few as possible, and high impedance of the transmission line caused by hollowing out the reference layer under the transmission lines can be avoided; and meanwhile, the place right under a bonding pad where the signal of the electrostatic protection device passes is hollowed out, so that the impedance formed after hollowing needs to meet the characteristic impedance requirement of the signal line, and the impedance of the signal, particularly a high-speed signal, passing through the PCB transmission line can be more continuous. 本发明公开了一种用于静电防护器件布线的PCB板结构及信号测试设备，通过对
