The essentials.

  • Coming soon

    8 mm panels. The nozzles sit in panels that retain heat and recover quickly at full load.5

  • Coming soon

    Double-pin chain. Carries the board without oil stains, with automatic lubrication.6

  • Coming soon

    Automatic width. The conveyor adjusts itself to the recipe.7

  • Coming soon

    Traceability. Logs every production run and is MES-ready.8

Three key points

Application examples.

What JTU highlights about the AR-601 and its AR series.

  • Boards moving through the heating zones of an AR series oven (image: JTU)
    Stable profile across the conveyor. In JTU's test (with an AR-1003), the 8 thermocouples across the width stay within 1 °C of the setpoint.1
  • Coming soon
    Large boards, no warpage. Less temperature difference across the board and, as an option, center support.9
  • Coming soon
    With nitrogen. The AR-601N version, with an optional oxygen analyzer.10
  • Coming soon
    One profile per board. With KIC ProBot (optional), no periodic manual profiling.11

Notes

  1. “Stable & Repeatable Profiles: ‘What you set is what you get’.” In JTU's test with an AR-1003 (for reference only), 8 thermocouples spread across the 400 mm conveyor width stay within 1 °C of the set temperature: JTU AR series catalog, p. 2.
  2. 6 top and 6 bottom heating zones; 2,330 mm heating zone; 1 top cooling zone, 400 mm long: JTU AR series catalog, p. 5.
  3. Closed-loop PID control with SSR, ±1 °C precision; temperature deviation on the board ±1.5 °C: JTU AR series catalog, p. 5.
  4. Convection with front-to-back flow: minimizes heat migration between zones, which is common in left-to-right flow systems: JTU AR series catalog, p. 2.
  5. Nozzles integrated into 8 mm heater panels, which store energy to recover quickly at full load, are easier to clean and reduce maintenance downtime: JTU AR series catalog, p. 2.
  6. Double-pin chain, which keeps oil off the board, and programmable automatic lubrication: JTU AR series catalog, p. 3.
  7. Automatic conveyor width adjustment by recipe: JTU AR series catalog, p. 4 and 5. Automatic recipe changeover with a barcode reader is optional (p. 4).
  8. Production process data is logged, with full traceability; ready for MES integration (optional customization) and IPC-CFX (optional): JTU AR series catalog, p. 4.
  9. Longer effective zones: less ΔT across the board and less warpage (p. 2). Optional center board support (CBS) for large boards; with it, the mesh is removed and the minimum board width becomes 60 mm: JTU AR series catalog, p. 3 and 4.
  10. AR-601N: nitrogen at 0.5–0.8 MPa and 10 ppm; 21 m³/h to reach 500–1,000 ppm (p. 5). Oxygen analyzer optional, on N versions only; nitrogen/air switching is not available on 6-zone ovens: JTU AR series catalog, p. 4.
  11. KIC ProBot automatic thermal profiling (optional): “1 PCB, 1 profile”, with no periodic manual profiling: JTU AR series catalog, p. 4.
  12. Table from the JTU AR series catalog, p. 5 (AR-601 and AR-601N columns). Up to 350 °C as an option (p. 4). It is the same table as in the English brochure you can download on the website (v10.0.1, p. 5).
