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

<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 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 ±0.3mm
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
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 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.
