Thanks to all who have responded to my inquiry.  I am experiencing a download issue with IHS.   I tried to download IPC/J-STD006 several time now and it freezes in the middle of the download.  Its onlt 436.8KB.   I will try again later.

Victor,

Subject: Re: [TN] LF Solder melting point

Not exactly on topic, but TechNetters may be interested to know I just got finished reading a paper from 2014 APEX EXPO about lead-free and possible aerospace applications. A couple of SnAgBi formulations (I think solders do not qualify as alloys) may have been the best performers. Things got a little complicated, with varying laminates and final finishes, but the paper looked interesting. Louis Hart

Just had this conversation today. I think most people think SAC305 when they think Pb-free. But, SnBi is also Pb-free. Quite a difference in melting point.
If you are thinking this way, about 220 celsius. SnBi, about 140 celsius. I say about because I like a little silver added for mechanical performance.
