Ultrasonic Soldering

Ultrasonic Soldering

Ultrasonic Soldering

Ultrasonic soldering is an environmentally friendly joining technology that enables direct metal bonding without the use of flux by removing surface oxides through ultrasonic vibration. It is a method in which high-frequency mechanical vibrations in the ultrasonic frequency range generate cavitation in the molten solder, removing oxide layers from the metal surface and thereby enabling soldering. As a result, clean joints are formed without flux residue, enabling stable and reliable ultrasonic soldering between dissimilar metals such as aluminum and copper, with excellent electrical and mechanical performance.

Applications

Ultrasonic soldering is widely applied to metal wire, terminal, and PCB joining processes across industries including electronics and electrical equipment, motors, home appliances, automotive, and industrial power systems. It is particularly suitable for eco-friendly manufacturing where flux usage is restricted, high-reliability electronic modules, and components requiring high heat resistance and electrical conductivity. Compared to conventional thermal soldering, the process operates at lower temperatures and shorter cycle times, minimizing component damage and preventing galvanic corrosion while improving electrical reliability.
