摘　　要：应用Designer与HFSS联合仿真技术研究激光焊接工艺对连接性能的影响。首先,在HFSS中建立一个标准的BGA焊点模型,通过改变其尺寸参数仿真,得到使回波损耗最小的参数组合;随后,在Designer中建立激光模型,把HFSS中的焊接连接工艺模型以N端口元件的形式嵌入到Designer建立的激光中,进行联合仿真;最后,对嵌入焊接连接工艺前后的仿真结果进行对比分析,得出焊点及焊点尺寸的改变对激光性能的影响。在高频段,随着焊点高度的增加,焊点的回波损耗随之减小,当焊点高度为0.50 mm时,回波损耗最小,因而应优先选择0.50 mm的焊点高度。The effect of laser welding process on the performance of the connection was studied by Designer and HFSS joint simulation technology. A standard BGA solder joint model was established in the HFSS, the simulation was carried on by changing the size parameter. The laser model was set up in the Designer, then the HFSS welding connection process model was embedded in the Designer in the form of N port element. Finally, the simulation results were analyzed, and the effect of the change of solder and solder joint size on the performance of the laser was obtained. With the increase of solder joint height, the return loss of solder joints decrease, when the height h is 0.50 mm, the return loss is minimum.
