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 12, bottom 12 (4675mm) 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 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 0 to 2800, 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 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 | Panasonic adjustable 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 motorized adjusting |
Machine structure |
Frame | The frame is well soldered, firm and durable. |
Door | Dismountable structure, provide wide space for maintenance. |

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. |
