摘要
通过采用F&K超声检测系统检测劈刀的安装方式对超声换能系统的性能影响,从最基本的实验数据(谐振频率,相位及阻抗)出发,分析劈刀引起换能系统的非线性特性,为设备工艺窗口参数调节提供理论基础。
Experimental results with F&K ultrasonic test system show the influence of bonding tool setting height on ultrasonic system. Experimental data such as resonant frequency, phase and impedance is helpful to nonlinear analysis of transducer system, and provide theoretical basis for process window adjustment of wire bonder.
