Explanation of the second-hand Jintuo small 8-zone reflow soldering furnace

1. Preheating zone
The preheating zone is heated to 175 degrees Celsius for about 100 seconds, from which the heating rate of the preheating zone can be obtained (as this tester uses online testing,
So from 0-46 seconds, we haven't entered the preheating zone yet. Time 146-46=100 seconds, and due to the room temperature being 26 degrees, 175-26=149 degrees Celsius
The temperature rate is; 149 degrees/100S=1.49 degrees/S)

2. Constant temperature zone

The high temperature in the constant temperature zone is around 200 degrees Celsius for 80 seconds, with a temperature difference of 25 degrees Celsius between the high and low temperatures

3. Reflux zone

The high temperature in the reflux zone is 245 degrees Celsius, and the low temperature is 200 degrees Celsius, with a peak time of approximately 35 seconds; Heating rate of reflux zone
According to (how to correctly set the temperature curve), it can be concluded that the time it takes for this temperature curve to reach its peak is too long.
The entire reflux time is approximately 60 seconds

4. Lingque District

The time in Lingque District is about 100 seconds, and the temperature drops from 245 degrees to around 45 degrees. The speed of Lingque is: 245-45 degrees=200 degrees/100S=2
