Application of Ultrasonic Soldering Iron

No need of flux when soldering to the glass, ceramic, or metal (the end of iron tip makes ultrasonic vibration, and removes any contaminants or oxide layers on the surfaces)
Ultrasonic soldering machine made soldering on glass, ceramics, tungsten, molybdenum, titanium, nitrides and carbides possible, all thanks to the bond created with an oxidated layer on the substrate surface.
