RF-430 Model-1/IR IR+Natural convection system
RF-430 Model-2/IRN2 IR+N2 system
RF-430 Model-3/HA IR+Hot air convection system
RF-430 Model-4/HAN2 IR+N2 convection system
RF-430 is a small reflow soldering machine based on far-infrared and hot air heat convection, and designed
specially for nitrogen gas (N2).
As this series is of IR 4 zone type, a stable temperature profile can be obtained.


  • This is table top type N2 reflow soldering machine. (O2 density : about 5000ppm)
  • The heating source is IR and hot air heat convection, consisting of 4 zone heating sections.
  • In future you can modify the basic model to the model applicable to N2. (with manufacturer's assistance)


  • Heating section : 4 zones, (W)300× (L)980× (H)50mm (at the inlet)
  • Heater : Quartz tube heater, IR (wavelength: 2 to 10 μm)
  • Each zone : Upper part: 1.2kW (200V) / 1.4kW (220V)
