4	40s	265°C
5	120s	40°C

Final profile

Comparing this profile to the 'ideal' solder profile, the main difference is that we do not dwell on the 'pre-heat' phase (ie. 150-200°C). This is because we could not get the temperature to rise fast enough, so we were forced to stick to a steady, slow ramp.

Results

The second run of 0603 resistors was a success
Some very fine pitch ICs
