Anyone know of a paste supplier that can provide the 42Sn/1Ag/57Bi alloy? Supposedly HP has done some work with this specific alloy and we would like to evaluate it. Neither Alpha Metals or Kester can supply it.

It doesn't appear to be a proprietary mix. Maybe it's 'neither Alpha Metals nor Kester WILL [want to] supply it.'

It's interesting. A lot of the discussion of a solder replacement for 63/37 has centered on high temperature alloys. In real life, most the applications that will actually be replaced with a no-lead solder will probably get along just fine with lower temperature alloys. It�s not like they going to do no-lead in automobiles, airplanes, safety oriented / critical industrial applications, medical equipment, etc.

I�ve seen some talk of that alloy in High Density Packaging User Group [ http://www.hdpug.org/ ] Low Temperature Soldering Reliability Characterization Project [ http://www.hdpug.org/public/projects/reliab_char/low-temp/descr.htm ]. Maybe they can help you.

Actually this is for automotive (radio). According to TWI (the Welding Institute), European auto makers are mandating that suppliers of electronics replace lead in solder by January 1, 2003. I haven't been able to find which specific automotive companies, and this is contrary to all info we had received previously.
