Abstract: A lead-free solder contains 93.0 mass % or more and 98.95 mass % or less of indium, 1.0 mass % or more and 4.0 mass % or less of tin, and an addition metal. The addition metal contains at least one of silver, antimony, copper, or nickel. The addition metal is neither indium nor tin. The total of mass percentage of the addition metal is 0.05 mass % or more and 6.0 mass % or less. The sum of the total mass percentage of the addition metal, the mass percentage of indium, and the mass percentage of tin is 100 mass % or less.

Abstract: A glazing is disclosed comprising at least one ply of glass having an electrically conductive component on at least one surface, and an electrical connector electrically connected to the electrically conductive component through a soldered joint, the solder of the joint having a composition comprising 0.5 wt % or more indium, wherein the electrical connector comprises a nickel plated contact for contacting the solder. Also disclosed are solders having a composition comprising 14 to 75 wt % In, 14 to 75 wt % Sn, to 5 wt % Ag, to 5 wt % Ni, and less than 0.1 wt % Pb. Also disclosed is use of a solder having a composition comprising 0.5 wt % or more indium to solder a nickel plated electrical connector to an electrically conductive component on the surface of a ply of glass. The aspects of the invention improve the durability of electrical connections on glazing.
