The new generation desktop soldering robot for Industry 4.0 and IoT.
UNIX-DF Series have improved its network function and robotic motion.

Desktop soldering robots enable a compact, repeatable automated soldering station—delivering stable quality by simply executing programmed operations.

Three types are available according to PCB size. They support network connectivity to visualize each soldering process and results. Optional additional axes enable penetration angles or PCB rotation, making difficult components feasible for automated soldering.

*UNIX-DF203L and UNIX-DF403L are also available.

Desktop footprint and familiar DF operability remain the same, while enabling laser soldering integration for non-contact, repeatable heat input.

1. Improved network functions for industry 4.0 OPTION

Connecting to factory network and making operation visible in real time.

Industry 4.0 connectivity concept for DF series
  • The relationship between factory network and DF series.
    PLC, LAN and hubs are as provided by customers.
  • Supporting data export and external process control via LAN or COM port.
  • Monitoring software can remotely monitor operation status.
  • Real-time monitoring (temperature graph, operation status, errors) helps prevent defects.
  • Robots can be controlled by PLC with control commands.

2. 3D soldering and MID (molded interconnect device)

Two additional axes enable complex PCB soldering easy and flexible.

Additional axes option for DF series
  • Two axes can be added to the work area.
  • Up to two axes can be added (up to six axes total).
  • External devices can be controlled together with the robot batch operation.
  • Supports various motions: component rotation, PCB reversal, head angles, cylindrical rotation, cable suppression, etc.
  • Space-saving and easy to set up.

3. The new heater highly improves productivity.

Higher accuracy and improved temperature characteristics.

DF series heater structure
  • More accurate temperature measurement by placing the heat sensor at the tip end.
  • Quick temperature recovery achieves higher operational efficiency.
  • Heater and tip are separated; replace individually.
  • Poka-yoke function prevents installation mistakes of soldering tip and direction.

Easy to change program selection on the switch box

DF switch box
  • The center switch can quickly change programs.
  • One touch selector on the switch box
  • Arbitrary programs are simply selectable and executed (2ch)

4. For Industry 4.0. Data management of each soldering process

By connecting DF monitoring software, soldering processes (temperature, program execution, errors) are visualized and converted into numerical data.

Soldering Manager monitoring screen

Monitoring temperature behavior and program execution can help detect anomalies and notify errors. By connecting to Internet/intranet, notifications can be sent to registered email addresses for faster response. Data can be exported as CSV for analysis and continuous improvement. Advanced management software “Soldering Manager” (paid version) is also available.

5. Managing invisible defect modes

UNI-TESTER compatible (optional)
To maintain stable soldering quality, not only measuring tip temperature, but also measuring tip leakage voltage and ground resistance is important for process control.

UNI-TESTER soldering iron tester

Tip temperature instability affects solder joint finish. Leakage and transient voltages can damage components internally. From a device-protection viewpoint, resistance between tip and ground must be measured and secured. UNI-TESTER compatible with IEC-61191-1 (Ed3 / 2018) and IPC J-STD-001G enables measurement and automatic tip temperature offset.

Three Methods to Choose From

Iron Tips

Safe and reliable construction methods backed by tradition

Automated tip soldering method

Tip soldering has the longest history and is an established technology in reliability. Modern applications require deeper soldering theory and techniques for difficult cases.

Laser

The latest soldering method attracting global attention.

Laser soldering method

Laser soldering is not a direct substitute for tip soldering because the heating mechanism differs. To gain full benefits, understanding characteristics and proper handling is vital.

Ultrasonic Soldering

Ultrasonic enables soldering even on glass or ceramics

Ultrasonic soldering method

Conventional soldering bonds solder with metallic substrate. Ultrasonic enables bonding on glass or non-metallic materials.
