Abstract
Many known solder alloys according to prior art utilize silicon or boron as melting point reducers, which, however, form brittle phases that have an undesirable effect on the thermo-mechanical properties. The invention relates to a solder ally that comprises gallium and/or germanium, preferably forms the Y' phase and has improved mechanical properties.
