A comparative study of Sn3.5Ag and Sn3.8Ag0.7Cu for BGA spheres on Ni/Au finish
A comparative study was conducted with Sn3.5%Ag and Sn3.8%Ag0.7%Cu solder balls on Ball Grid Array (BGA) packages with Ni/Au pad finishing. The study was carried out in different levels. At individual solder joint level, Sn3.5Ag showed no intermetallic brittle failure in cold ball pull test under an...
