Cooling system

Cooling method

Forced air cooling

Cooling zone

3 cooling zones, length is 960mm, cools down the PCB quickly and reduce the heat impact when the PCB exit from the oven, PCB surface temp. is ≤70℃ at the exit.

Cooling flux management

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

Heating features

Heating zones

Top 10, bottom 10 (3892mm) can meet the need of the peak lead-free technique.

Heating method

Hot air, the speed of all hot air motors is adjustable from software.

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

Generate the profile for each zone daily, user can review and analyze. This function is not for PCB profile testing, just for inspecting when some problem happens in a certain zone.

Production database

Generate production statement for all kinds of PCB and statistics, printable.

Alarm list

The system saves all alarm information for user to review the alarm item and time.

Alarm system

The system enters cool down mode when the alarm is strict.
