Pb-free Sn—Ag—Cu—Al or Sn—Cu—Al solder
Abstract
A solder alloy includes Sn, optional Ag, Cu, and Al wherein the alloy composition is controlled to provide a strong, impact-and thermal aging-resistant solder joint that has beneficial microstructural features and is substantially devoid of Ag3Sn blades.
