SMD Assembly Line SMT Reflow Oven for LED Panel Lights
Heating System
> seven 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, PCB drop, PCB jam 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 forced air convection cooling zones.
Distortion-free Conveyor System with Automated Chain Lubrication
> Combined pin chain rail and mesh belt conveyor system (Note: Mesh belt is not available on machines with center board support. )
> Closed-loop computer control of the conveyor provides a precise and repeatable reflow process.
> Automated chain lubrication system with a computer controlled central reservoir. Lubricant is added directly to the conveyor brush eliminating operator interface for this maintenance.
Fresh Air Recharge System> Fresh air is supplied to each zone uniformly to provide a rapid process transfer.
Flux Management System
> Air amplifier forces supercharged flux collection and recirculation.
> Flux exhaust chimney with drawer shaped filter net is easy to access for maintenance.
Control System
> PC control system with windows based control software.
Additional Features> Integrated UPS will be automatically activated in case of main power failure and will keep control PC and conveyor running for minimum 8 minutes to send out PCBs inside the oven tunnel.
> Motorized hood lift allows easy access to the inside of the oven for service and maintenance.
> Five (5) profiling ports and integrated profiling software are designed for convenient temperature profiling.
> Swing arm control PC station
> Four (4) emergency stop switches
> Two (2) exhaust ports
> SMEMA interface
