摘 要：为了提高爆炸箔起爆器的制造效率和产品一致性，设计和制造了一种基于柔性电路板（简称 FPC 或软板）制造工艺的集成
冲击片换能元，并对该集成换能元的电爆炸性能、驱动飞片能力和起爆六硝基茋的能力等基础性能进行了研究。采用高压探头测量
了爆炸箔两端的电压曲线，采用罗果夫斯基线圈测量了放电回路的电流曲线，通过光学多普勒测试手段（PDV）测量了电爆炸过程
驱动飞片速度历程曲线。结果表明，放电回路峰值电流和桥箔的爆发电流随着电容两端电压的增加而线性增加，其中桥箔的爆发电
流从 2080 A 增加到 2680 A。桥箔的爆发时间随着电容两端电压的增加而线性地从 232 ns 减小至 156 ns。随着充电电压的增加，
