Cooling system

Cooling method

Forced air cooling

Cooling zone

3 cooling zones, length is 1140mm, cool down the PCB quickly and reduce the heat impact when the PCB exit from the oven.

Cooling flux manage

With separate flux management in the cooling zone, make it clean all the time, easy for maintenance.

Heating features

Heating zones

Top 8,bottom 8(3110mm)can meet the need of the peak lead-free technique.

Exit temperature

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

Profile transfer time

<15min

Heating zone temp. control accuracy

±1℃

PCB temp. deviation

±1℃

Empty to full load heat balance respond time

≤20 s

Heating zones separately close function

Every heating zone can be closed separately on computer. When the bottom heating zones are closed, the PCB two sides temp. different reaches max.(PCB of different material, thickness, size, the temp. difference value is different.)
