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

Achieve 1) Improved network functions for industry 4.0

* 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.
  • Special monitoring software can remotely monitor operation status.
  • ・The real-time monitoring such as temp. graph, operation status, errors can prevent defective products.
  • ・Robots are controllable with connecting to PLC and with control commands.

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

Two additional axes enable complex PCB soldering easy and flexible.

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

* Two axes can be added to the work area.

  • ・Two axes can be optionally added, up to six axes are available.
  • ・External devices are integrally controllable with the batch operation of robot.
  • ・Various motions such as component rotation, PCB reversal, head angles, rotation of cylindrical parts, cable suppression, etc.
  • ・Space saving and easy to setup.

Achieve 3) The new heater highly improves productivity.

Higher accuracy and improved temperature characteristics.

Achieve 3) The new heater highly improves productivity.
  • ・Much more accurate temperature measurement has been achieved by placing heat sensor at the tip of the tip.
  • ・Quick temp. recovery achieves higher operational efficiency.
  • ・The heater and the tip are separated and can be replaced individually.
  • ・Poka Yoke function prevents to make mistakes of installing a soldering tip and its direction.

Easy to change program selection on the switch box

Easy to change program selection on the switch box

* The center switch can quickly change programs.

  • ・One touch selector on the switch box
  • ・Arbitrary programs are simply selectable and executed (2ch)

Achieve 4) For Industry 4.0. Data management of each soldering process*

By connecting DF monitoring software, various soldering processes such as temperature, program execution and so on are visualized and converted into numerical data.

Achieve 4) For Industry 4.0. Data management of each soldering process*

For example, observing the temperature during soldering, if irregular temperature change or program execution occurred, the monitoring system captures their irregularity and can notify errors.

Furthermore, connecting to the Internet / intranet, the system can notify error and can send alert to the registered email. Such real-time observation enables you immediately respond to operation errors and defects.

Any data can be exported with CSV format. Various operational log data from each process can be useful for investigating and exploring for further productivity improvement.

Further advanced soldering management software “Soldering Manager” (paid version) is now available.


Achieve 5) Managing invisible defect modes

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

Achieve 5) Managing invisible defect modes

The tip temperature instability affects the solder joint finish. Leakage and transient voltages can cause components’ internal damages. From the viewpoint of device protection, the resistance between the tip and ground must be measured and secured.

UNI-TESTER compatible with IEC-61191-1 (Ed3 / 2018) and IPC J-STD-001G can realize various measurements and automatic tip temperature offset at the same time.
