TechNet Group, I'm evaluating a low-melt Sn/Bi solder alloy for plastic BGA repair. This seems to work very well, but I need to learn about the interface between Sn/Bi and the Sn/Pb solder (on the BGA and board). Does anyone have experience with this combination? Thank you for any comments, suggestions, web links, etc that may provide information.
