Cooling system

Cooling method

Forced air cooling

Cooling zone

2 cooling zones, length is 700mm, cool down the   PCB quickly and reduce the heat impact when the PCB exit from the oven. After   cool down by air, PCB 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 8, bottom 8 (3110mm) can meet the need of   the peak lead-free technique.

Warm up   time

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

Warm up   sequence

Warm up from two sides, save the power and time

Profile   transfer time

<15min

Heating   zone temp. control accuracy

±1℃

PCB temp.   deviation

±1.5℃

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.

Heater

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

Air lane   structure

Highly 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

±0.3mm

Chain   stretches 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

Mesh

500mm stainless steel mesh, runs synchronized   with chain

Machine structure

Frame

The frame is well soldered, firm and durable.

Door

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

Windows 10 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 modes: 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.
