Can anybody point me to some research, or experimental findings, etc., of the formation of the very low melting point alloys which form from the 43Sn43Pb14Bi alloy after it is reflowed? Previous inquiries about this alloy left me with replies that stated after reflow, some different alloys are formed which have a liquidus ~98C. Are there published details? Online publications would be much appreciated, but books can be researched if necessary.
