Heating features

Heating   zones

Top 12,bottom 124675mm)can meet the need of the peak lead-free   technique.

Cooling   zones

After cool down by 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

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.)

Heating   parts

Hot air motor

Import anti high temperature motor,RPM:2800rpm。Adopts inverter to control, can adjust the   speed of motor from 0to 3000, stepless. Motor warranty is 5 years.


The heater is specially made, with high efficiency and sensitivity,   warranty time is 5 years.

Air lane structure

High efficient air lane, provides abundant air

Exhaust system

Forced exhaust device, ensure no escape of flux.

Transmission   parts

Anti torque rail

High strength and hardened rail, is very durable and wear resistant.

Rail parallelism


Chain stretch out length

Standard: 5mm, the chain is anti-stuck type, solve the soldering   problem of small PCB

Working mode

Three working mode: operation, edition and presentation, with on-line   editing function

Real time monitor

Generate the operation record daily, if there happen some problems, the   responsible operator will be found easily.

Temperature profile

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.

Profile test

With temp. profile testing function, can analyze according to the   profile.

Abnormal alarm

1.PCB runs abnormally 2. Operation abnormal 3.Temperature abnormal 4.Conveyor   speed abnormal  5.Hot air devices   abnormal.

Flux recycle device

Standard configured. When use nitrogen, as it is closed recirculation,   if the flux fog cannot be spread, it will pollute the PCB.
