The invention relates to an electrically conductive wire (
1) comprising two spaced solder balls (
2) thereon and flux (
4) in the space (
3) between the solder balls for making a circuit connection between electrically conductive members on opposite surfaces of a substrate. The wire (
1) is inserted in a through-hole of the substrate and soldered by a customary soldering process, like wave soldering.
