dcterms.abstractAn ultrasonic transducer for welding small elements by applying pressure and ultrasonic energy simultaneously has an ultrasonic stimulator composed of 4 crystal wafers isolated by electrodes and welding head of ceramic crystal wafer. Its advantages are wider bandwidth, and low noise resonance.-
dcterms.abstract一种同时施加压力和超声能量以使小型元件焊接在一起的焊头，包括一个具有由电极１５分隔的四个复合晶片１７的超声激励器。已知的焊头采用由全陶瓷材料构成的晶片。通过采用由所示聚合物层分隔成四个陶瓷材料扇形部分的晶片１７，焊头具有较宽工作带宽，并且减少噪声谐振模式。-
