| 印刷电路板(printed circuit board,PCB)易受到静电放电的危害,继而影响电子产品的正常使用。 为了获得 PCB 的静电
放电能量耦合规律,对简化的 PCB 进行静电放电测试。 通过对 PCB 轨线上的耦合电压的测量,研究了放电位置、轨线特性及放
电电压对静电放电电磁场耦合的影响。 测试结果表明,放电位置、轨线宽度、长度和端接电阻会影响耦合电压的大小和变化趋
势,放电电压和耦合电压呈现良好的线性关系。 同时,根据在电磁仿真软件( compilation simulation technology microwave studio,
CST-MWS)中建立的全波模型,从仿真的角度进一步论证了测试结果。 研究结果对 PCB 电磁兼容设计具有一定指导意义。 |
| 英文摘要: |
| Printed circuit board (PCB) is sensitive to electrostatic discharge, which affects the normal use of electronic product. In order
to obtain the energy coupling law of electrostatic discharge (ESD) with PCB, ESD test was applied to the simplified PCB. The effect of
the discharge position, characteristics of the PCB trace and discharge voltage on the coupling of ESD electromagnetic field was studied by
measuring the coupling voltage on the PCB trace. The test results show that the discharge position, trace width, length and termination
resistor will affect the magnitude and trend of coupling voltage and there is a good linear relationship between the discharge voltage and
the coupling voltage. Based on a full wave model that is also established in compilation simulation technology microwave studio, it further
nstrates the test results from the standpoint of simulation. The research results have certain guiding significance for PCB electromagnetic
compatibility design. |
