摘要
通过对标准QFP引线框架的改造,实现了一种高频集成电路芯片的封装设计。介绍了利用电磁场仿真软件进行封装的3D建模,并提取封装结构的模型参数,进行信号完整性分析的方法。实例验证表明,此方法以较低的封装成本,较好地减少了长键合线及框架引脚对高频信号的影响,在现有的封装技术基础上提供了实现高频/高速集成电路封装的新思路。
By modified the leadframe of standard Quad Flat-Packs, a packaging design for high frequency IC was completed. The package 3D model created by electromagnetic simulation software was introduced and the method about how to extract the model's parameters for signal analyzing was presented. The simulation results show that this method greatly reduced the effect of long bondwires and leaders at lower cost. It gives a novel packaging method for high frequency IC based on packaging technology at present.
