Cooling system

Cooling method

Forced air cooling

Heating features

Heating zones

Top 8,bottom 8(3110mm)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

Profile transfer time


Heating zone temp. control accuracy


PCB temp. deviation


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.)

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

C/V speed set min.unit range

0.01m/min, 0~2m/min

C/V speed deviation range

Computer close loop, within ±2%

Chain tension device

Automatic adjust by spring, avoid the chain stuck due to the heating.

Conveying motor

Taiwan motor

Chain lubrication

The lubrication is controlled by PC, lubrication cycle and time can be set(there are three modes: fine, standard, economical. There is also manual lubrication in software)

Rail width-adjusting

Independent adjusting


500mm stainless steel mesh,runs synchronized with chain

Machine structure


The frame is well soldered, firm and durable.


Dismountable structure, provide wide space for maintenance.

Hood open method

Double electric cylinder to open the hood, with self-lock function, safe and reliable.

Cover open method

Self-made holder, easy to clean up


Electrical parts and control performance

Control system

Industrial PC

PLC+Modular+PID, stable and reliable, with high repeat accuracy

Operation interface

Windows7 with Chinese& English shift easily.

Machine&operator safety

With creepage protector

Electric part

All electric parts are imported, very durable, ensure the machine runs stably.

Working mode

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

Real time monitor

Generate the operation record daily, if there happens 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.
