Normally the specs I monitored in our temperature profiles are Slope 1-2 Deg C/sec, preheat 60 - 120 Sec at 120 Deg C - 150 Deg C, peak 215+/- 10 Deg C, above 183 Deg C is 45 - 75 Sec, total reflow is 3 - 5 minutes.
Why is it that we don't monitor the spec on the time between 150 deg C to 183 deg C ? What actually happen at this stage ?
Pls help me to understand. Thx.
