In a conventional Sn—Zn based lead-free solder, Zn crystallized to a large size of several tens of micrometers, and it was difficult to suppress the formation of coarse crystallizates and to increase the bonding strength without changing the soldering temperature. There were alloys which improved strength by the addition of a minute amount of a Group 1B metal, but the alloys had an increased melting temperature so that reflow could not be performed with the same temperature profile as for Sn—Pb, so the alloys had advantages and disadvantages.By using a solder paste formed by mixing an ethanol solution containing nanoparticles having a particle diameter of 5-300 nm and containing at least one of Ag, Au, and Cu with a flux and solder powder for an Sn—Zn based lead-free solder paste, the formation of an alloy of Au, Au, or Cu with Zn occurs during soldering, thereby forming fine clusters in the resulting liquid phase of molten solder, and a fine solder structure is obtained following melting.

The local reference brackets are selected via optimization of an objective function which includes both a component that measures exposure quality of individual tiles and a component that measures correlation between neighboring tiles.
