Abstract Field Induced Charged Board Events (FICBE) experiments were conducted. The waveforms were verified using charged device model (CDM) standards. The discharge probe was constructed to determine the electrostatic discharge sensitivity of a PCB. The standard CDM current waveforms were used as a reference to ensure proper function of the discharge probe. The investigation revealed that a lower impedance of a pogo pin improved the sensitivity. The parallelizing of a pair of 2 Ω resistors reduced the parasitic inductance. Inclusion of a ferrite bead on the current sensing wires reduced the common mode noise. This test bench complies with standard CDM current waveforms.

基于 CDM 波形验证的 FICBE 测试使用放电探针的寄生阻抗效应研究

摘要 进行了场致带电板事件 (FICBE) 实验。波形已使用充电设备模型 (CDM) 标准进行验证。放电探头用于确定 PCB 的静电放电灵敏度。标准 CDM 电流波形用作参考，以确保放电探头的正常功能。调查显示，弹簧针的较低阻抗提高了灵敏度。一对 2 Ω 电阻器的并联降低了寄生电感。在电流感测线上包含铁氧体磁珠可降低共模噪声。该测试台符合标准 CDM 电流波形。
