Heating features


Heating   zones

Top 8,bottom 83110mmcan meet the need of the peak lead-free technique.


Cooling   zones

After cool down by forced air, PCB temp. is ≤70℃   at the exit.


Warm up   time

From the normal temp. to set temp, approximate 30 minutes.


Warm up   sequence

Warm up from two side, save the power and time
