根据超声引线键合实验平台电路结构，设计了PZT(压电陶瓷)驱动信号采集电路。
According to the circuit of ultrasonic wire bonding experiment platform, a piezoelectric transducer (PZT) driver signal acquisition circuit was designed.
实验采用单光路临界角法，用四象限探测器探测输出信号，物面微位移采用压电陶瓷作为驱动元件。
The experiment came into use single light path critical angle method, output signals were detected by four-quadrant receiver, micro-displacement drive element were piezoelectric ceramics.
系统控制方面，通过单片机系统产生四路信号，经驱动电源直流放大后加载到压电陶瓷微位移器上。
As to controlling system, the four-channel signals from MCU are output to DC amplifier to be amplified and then loaded to PZT platform.
