After half an hour's fruitless searching of the net I thought of Technet.

Can anyone out there point me at a web page or email me a reflow profile for one of the higher
melting point lead free solders. I'm trying to produce a test spec to determine whether some
temperature sensitive components would survive a 'worst case' reflow cycle.

By the way. I note that many of the lead free alloys contain Bismuth. Isn't this more toxic
than lead? Am I being naive in my surprise that one toxic chemical is being replaced with
something equally bad?

Regards,
