The invention relates to solder materials, such as a solder paste (11), and contact surfaces for solder connections, wherein according to the invention a metal stearate is used as a flux, said metal stearate being applied either as a solid layer (14, 15) on the solder particles (12) or as contact surfaces (not shown) or being present as a dispersion or solution in the binder.
