ETA E10 Lead free hot air reflow oven 

Heating System

> Ten 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
