Some of my friends ask me if sombody use lead free solder ball on BGA, espically PBGA packages. I wonder if 96.5Sn/3.5Ag (m.p .221 oC) or 58Bi/42Sn (m.p. 138 oC) would be suitable candidates? Do you have any experience on this subject? Kelvin

Jason: How did you determine that the deposits are tin oxide? What does this stuff look like? Klein Wassink "Soldering in Electronics" (p. 221, quoting original work by others). States (in effect) tin (or solder) quickly forms a protective oxide
