What is Ultrasonic Soldering?

Ultrasonic soldering is the process of pretinning or metallizing the surface of almost any given material using an ultrasonic sonotrode instead of flux (Edison Welding Institute,USA) Ultrasonic soldering is a fluxless joining method in which high frequency mechanical vibrations replace the flux. The mechanical vibrations are transmitted to a liquid solder bath, and the energy of the mechanical vibrations causes cavitation to occur, thus eroding the surfaces of parts immersed in the bath. This removes the oxide layer on the surfaces of the parts and allows the melted solder to wet the clean metal surfaces.
