|Top 8, bottom 8
|Cooling zones qty.
|Heating zone length
|3P 380V/220V 50/60HZ
|Temp. control range
|Temp. control accuracy
|Temp. control method
|PID +SSR drive
|PCB temperature deviation
|All profiles can be saved
|Warm up time
|High, low temp. alarm
|2 sectional rails
|Rail fixed method
|PCB Max. width
|Rail+ mesh+ chain
|Left to right
Forced air cooling
|Top 8,bottom 8（3110mm）can meet the need of the peak lead-free technique.
|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
|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.)
|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
|Forced exhaust device, ensure no escape of flux.
|Anti torque rail
|High strength and hardened rail, is very durable and wear resistant.
|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
|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.
|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）
|500mm stainless steel mesh，runs synchronized with chain
|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
|PLC+Modular＋PID, stable and reliable, with high repeat accuracy
|Windows7 with Chinese& English shift easily.
|With creepage protector
|All electric parts are imported, very durable, ensure the machine runs stably.
|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.
|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.
|Generate production statement for all kinds of PCB and statistics, printable.
|The system saves all alarm information for user to review the alarm item and time.
|The system enters cool down mode when the alarm is strict.
|With temp. profile testing function, can analyze according to the profile.
|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.
