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
