Lead-free reflow oven
- 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, 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.
- 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 re-circulation.
- Flux exhaust chimney with drawer shaped filter net is easy to access for maintenance.
- PC control system with windows based control software.
- 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
