摘要 挠性印制板很容易在大应力的作用下造成开裂或断裂,在设计时常在拐角处采用抗撕裂结构设计以更好地改善FPC的抗撕裂的性能。文中基于三维电磁场仿真软件HFSS,对多种圆弧拐角防撕裂结构的信号传输性能及电磁场分布进行了仿真分析,总结了防撕裂结构对高速电路信号传输性能的影响规律。 The FPC easily cracks or breaks under the influence of large stresses.An anti-tear structure is,therefore,used around the corner to better improve the anti-tear performance of FPC.The paper carries out a comprehensive study of various FPC corners＇ anti-tear structures using a full-wave electromagnetic simulator HFSS.The impact of multiple arc corners＇ anti-tear structures on SI and the cross-section electromagnetic field is analyzed by modelling and simulation,and the influence of various FPC corners＇ anti-tear structures on the transmission of high speed circuit signals is summarized.
