本成果研制的超声波搪锡机 ,已应用于导弹上的仪器和地面设备的电子器件的电装中。它是以锆钛酸铝压电陶瓷作换能元件。该压电换能器的机电耦合系数比铁镍合金换能器的机电耦合系数高 2～ 3倍 ,搪锡质量高 ,使用寿命长 ,可替代进口镍片。声头结构设计采用凸面声头座 ,导电片用 The results of the development of ultrasonic baking machine, has been used in missile equipment and ground equipment electronic devices in the electrical equipment. It is based on aluminum zirconium titanate piezoelectric ceramic transducer components. The electromechanical coupling coefficient of the piezoelectric transducer is 2 to 3 times higher than the electromechanical coupling coefficient of the Fe-Ni alloy transducer. The quality of the distilling tin is high and the service life is long, which can replace the imported nickel slice. Sound head structure design using convex sound head seat, conductive film
