Todd,
In our experience, the reason most people run between 235-250C is twofold: it produces less dross
and it gives the flux (especially No-Cleans) the best environment in which to be effective. In
many cases where a higher temperature is used, it was done to compensate for high levels of
oxidation or was implemented from a different process. Not knowing board thickness, component
quality, or density, it is likely that going to a lower temperature may produce a shinier fillet,
good wicking, and less dross in the pot.
