From our process modules of the modular soldering technique, the optimal modules with regard to process technology and efficiency are selected for the task and combined to proven stand-alone, rotary transfer or inline production concepts for total solutions.
The EUTECT module toolbox shows, that with individual modules or free combinations a lean, individual solution of proven modules can often be achieved for the task of a customer product.
SRS – Sustained Ring Soldering
The Sustained Ring Soldering module produces solder rings from common solder wires, which enable a new cycle time-optimised, highly accurate and economically sustainable assembly soldering.Using the newly developed SRS module, pre-assembled solder rings can be produced on the fly and placed on and around THT pins. These are then processed by means of laser, piston or induction soldering processes, as well as by means of IR emitters or hot air. The SRS module is a fully automatic ring production device that is used to produce specific solder rings from customer and product-specific solder wires, with or without flux core. Depending on the tool used, different solder wires with defined ring diameters can be produced. The automatically reproducible solder rings can be positioned manually, with the help of special tweezers and magazine dispensers, as well as automatically by means of a special, highly dynamic pick & place handling system on the solder joints to be processed or over the plated-through pins.

The EUTECT factor
Many pieces of the puzzle make the EUTECT soldering processes efficient and reliable.
This includes parameters such as minimized production costs, as well as low cycle times and downtimes.
To achieve this, we invest a lot of time in the development of our modules. We take our customers’ suggestions for optimization and incorporate them into the further development of each individual module. This results in constant further development of all EUTECT products.
Using the IW1 and IW1-2 mini-waves, we illustrate what this means in individual cases.
The EUTECT factor
E-CELLS, EUTECT Automation cells
Our scalable E-CELLS stand for efficient use of space as well as modularity with precision and sustainability.
With a grid dimension of 300mm in width and length, each automation cell can be individually adapted to a wide range of tasks in terms of size, optionally also in terms of height. To implement our EUTECT cradle-to-cradle principle even more sustainably, we have reduced the number of control cabinets and replaced them with centralised and easily exchangeable cabinet solutions. On the one hand, these cabinet solutions support service and maintenance efficiency, and on the other hand, they enable a new, less complex but more clearly structured wiring concept. And in addition to all these sustainable benefits, the rigidity of the automation cells has been increased by over 50%.
Modularity beyond the standard
- Tailor-made flexibility through cell extension in length and width
- Highest rigidity for precise soldering and automation processes
- Central control cabinet for efficient service and maintenance services
- Real sustainability thanks to integrated cradle-to-cradle concept
In the framework of an evaluation, the right kinematics modules are selected for the customer. The assemblies, possible workpiece carriers, cycle times, production volumes and the soldering modules used thereby play a part.
Different combinations of cells, handling- and process modules are possible according to the task. From this variety of combinations, individual solutions beyond the standard can be implemented, that are oriented to the customer requirements in every detail.

EUTECT – Integration of cobots
With E-ssembly, we are introducing a completely new “line” production concept that is characterised by maximum flexibility, dynamics and sustainability. The newly created possibilities point the way to the future, not only in electronics production and assembly and connection technology, but also in automation as a whole. By means of the E-cell concept, we offer a new basis for generating maximum customer benefit with integrations such as that of the floating 2D product transport system XPlanar from Beckhoff.
E-ssembly can be used for the following applications:

Inline Laser Automation with AOI
EUTECT automation platform Multiple Process Changer (MPC)
The MPC platform is a highly flexible automation solution for a wide range of tasks using a collaborative robot system from Mitsubishi Electric. The standard system is equipped with a light grid protected input and a rotary table for assembly input.
The MPC can be equipped with various tools. In addition to piston soldering heads, dispensers, screw or placement tools and grippers are also being considered for integration into the MPC. Depending on customer requirements, the MPC can be equipped with different tools for different applications. It is also possible to use a wide variety of tools in one work process.
The robot used is a MELFA assista from Mitsubishi Electrics equipped with the latest MR-J5 servo motors in all six axes, which eliminate the need for additional torque sensors.
Not only because of its high rigidity and industrial design, it can set solder dots with the same repeatability as a standard robot, but also because the MELFA assista can also be operated as an industrial robot.
Multiple Process Changer (MPC)
MELFA assista from Mitsubishi Electrics
The complete system MPC KL (piston soldering) can be equipped with piston soldering systems from JBC or HAKKO. The soldering iron sits firmly mounted on the arm of the robot, including the wire feed. Robots, control systems and soldering irons are a machine unit. The entire system is completed by the input area, which in the standard version consists of a rotary table for manual component assembly and a safety cell around the soldering process. Furthermore, a soldering tip holder is provided in the process surface itself, with which the fully automatic change of the soldering tips takes place. The same applies to the tip cleaning.
Soldering process can only be reproduced if individual process parameters and steps are controlled, monitored and documented. EUTECT has developed a large number of these controlled process steps in order to guarantee the traceability of the individual steps within the soldering process at all times.
Below are some examples of controlled EUTECT process solutions:
Monitored and regulated nitrogen supply
Barcode, RFID and specific reading and writing devices
Standard machine equipment
Suction monitoring by means of flow sensor technology
Flow is measured and the system is only started when the suction is functioning
