摘　　要：为了防止声表面波器件被自身的热释电静电烧伤,提出了一种新的静电防护方法。该方法采用导电介质来实现对声表面波器件引脚的良好接触,并建立了静电传导途径,实现了热释电静电的释放,解决了困扰声表面波器件的静电敏感问题。试验结果表明,该方法能有效预防静电烧伤,具有很好的实用性。In order to prevent surface acoustic wave(SAW)devices from being burned by their own pyroelectric static electricity,a new electrostatic protection method is proposed in this paper.In this method,the conductive medium is adopted to realize good connection with the pins of SAW devices.An electrostatic conduction path is built to discharge the pyroelectric static,thus the problem that SAW devices are sensitive to the electrostatic discharge is solved.The experimental results show that the proposed method can effectively prevent electrostatic burns and has good practicability.
