SMT Reflow Oven

lead-free reflow oven A800
Heating System
> Eight groups of top and bottom forced hot air convection heating zones.
> Patented heating plates in each zone uniformly transfer heat to the PCBs using forced hot air convection.
> Independent temperature control in each zone to ensure temperature uniformity within the process tunnel.
> Power consumption savings of 1/3 as compared to other systems.
> Patented motorized blower in each zone is designed to ensure stable air pressure, withstand high process temperature and is disturbance-free.
> Audible and light tower alarm for temperature limits and blower malfunction.
> Fast start-up (within 20 minutes) from room temperature to work temperature due to the high efficiency of the motorized heating plates.
Cooling System
> Two (2) groups of air fans convection cooling zones.
> Mesh belt conveyor system 
> Closed-loop computer control of the conveyor provides a precise and repeatable reflow process.
Control System
> PC control system with windows based control software.
>Lenove Computer and Siemens PLC
Additional Features
> Integrated UPS will be automatically activated in case of main power failure and will keep control PC and conveyor running for minimum 5 minutes to send out PCBs inside the oven tunnel.
> Three (3) profiling ports and integrated profiling software are designed for convenient temperature profiling.
> Swing arm control PC station
> Two (2) emergency stop switches
> Two (2) exhaust ports
