For many years, wave soldering has been used as a production technology in the electronics industry. A flux was always used to make soldering of devices and circuit boards possible. This paper presents a process step for improvement of the solderability of contact areas by low frequency plasma which makes the application of flux or activators completely unnecessary for wave soldering with an inert gas atmosphere.
