。[Claims for Utility Model Registration] A defoaming device for printed wiring boards, which includes a treatment tank, a frequency sweep oscillator, and a set of vibrators and impedance matching boxes, wherein the treatment tank is a device in which the printed wiring board is immersed. The frequency sweep oscillator generates a signal whose oscillation frequency changes repeatedly, and the transducer and impedance matching box perform processing based on the output signal of the frequency sweep oscillator. A defoaming device for printed wiring boards, characterized in that it generates traveling waves in water or processing liquid in a tank.
