<p>A lead-free solder alloy, characterized as having the following composition: Cu: 0.05 to 2.0 wt %, Ni: 0.001 to 2.0 wt %, balance: Sn. The solder alloy is completely free of Pb, and hence does not cause the environmental pollution by Pb. Further, the solder alloy can provide improved mechanical strength of a soldered joint part as a result of the alloying defined above.</p> |
