Abstract: An 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.
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。
