There are two primary equations that I know of. The first is more of a rule
of thumb and is based on an Arrhenius rate of reaction. The second, which is
recommended, is the Eyring Model. The IPC SIR Handbook (IPC-9201), which is
nearing publication, has a section detailing this equation. It can also be
found in the original report of the Low Residue Soldering Task Force. I
don't think it will come across well as an ASCII text message. If you will
give me a fax number or mailing address, I can send you the necessary
references.
