Eutect GmbH further developed and optimized its Sensitive Wire Feeder (SWF). The world’s only patented intelligent wire feeder can be used in conjunction with a laser (LL), iron (KL) or induction (IL) system for soldering assemblies. As part of its continuous product development, the Swabian soldering specialist is now presenting a new development version of the successful product.

“The SWF is one of our best-selling modules. Not only do we use the SWF in our special soldering systems for the electronics industry, but we are also increasingly selling the module itself to other assembly system providers, for integration into their systems,” explains Matthias Fehrenbach, Managing Director of Eutect GmbH, and continues, “For this reason, we are continuously optimizing the SWF. The current adjustments include a number of measures that once again raise the SWF to a new level.”

For one thing, the drive of the SWF is now shielded by a metal cover, which improved EMC compatibility. Furthermore, a new signal filter software has been added to the module. Thanks to these measures, the new generation of the SWF achieves even more precise measuring accuracy and stability during wire feed. In addition, the weight of the overall module has been reduced by 11%, allowing the SWF to be moved more dynamically when integrated on a robot arm. “We can thus further optimize cycle times. The overall design reduces the time required for the robot arm to settle, which also allows us to use a less expensive robot for select projects,” Fehrenbach elaborates.

Another adaptation optimizes integration in robot applications. For example, the metal spool that guides the wire from the wire roll dispenser to the SWF has been replaced by a tube of lower weight, which means that the wire roll can now be integrated very flexibly in the production cell. Thus, maximum flexibility as well as a reduction of the required space are achieved. The flexible mounting of the solder wire roll results in a weight saving of up to 1.3 kg when using a full reel, which corresponds to a reduction of approx. 50% compared to the previous weight.

Service and changeover friendliness were also taken into account in the optimization measures. For example, the sheet metal covers of the wire feeder housing can be removed without tools. The covers can now be removed easily and simply, as they are held in place by a magnetic mechanism without screws. It also is easier now to change between different wire diameters. Using simple sheet metal covers allows better accessibility of the diameter setting on the control wheel and encoder wheel swing arm. New and more variable SWF configurations, as well as the use of solenoids or spring packs, and a wire insertion aid supported and controlled by the force sensor also assist the operator. By pressing on the drive housing of the SWF, the wire is automatically fed, or retracted, without the operator having to execute a command within the software via the HMI. Simply by selecting the wire change via the HMI, the module enters that mode, allowing for a quick and easy changeover. “This allows us to save valuable time,” says Fehrenbach.

Eutect introduces service cart for wave soldering modules

To simplify maintenance and servicing of wave soldering modules, Eutect GmbH offers a versatile service cart designed for use directly on the machine. Each service cart is tailored to specific customer modules.

The service cart introduced here is suitable for all mini wave soldering modules made by Eutect.
“The IW1 and 2 mini wave modules can be serviced on the service cart itself. Among other things, a nozzle receptacle has been integrated for this purpose, which makes it very easy to clean and maintain the solder nozzle”, explains Jürgen Seibert, responsible for service at Eutect GmbH. Once a module has been removed from the machine, it can be placed on the service cart. Thanks to the ideal height of the cart, the secured module can be serviced on site without requiring further transportation. In addition to the complete module, individual parts, such as for instance the nozzles, can also be serviced on the service platform. All necessary tools and cleaning media are located in six drawers below the platform. “This means that the operator has all tools within easy reach,” Seibert continues. The carts are adapted to the IW modules used by the customer, as is the nozzle receptacle.

In addition to maintenance, minor repairs or disassembly’s can also be carried out by a trained operator. “Our goal is to maintain a module at its place of use. This means that when maintenance is carried out by our customer, the module does not have to leave the production area, but that the module can be maintained and reconditioned on site by trained personnel,” continues Seibert. For this reason, the service cart is equipped as standard with a variety of tools and cleaning media. Where worn out or consumed, these can be replenished easily via the new Eutect GmbH online store.

Eutect offers Level 1 training for customer employees, which is conducted by Seibert and his team. “When putting the systems into service we train the employees. Additional training for new employees or more in-depth training can be ordered from us at any time thereafter”, Seibert assures. These training courses ensure that production staff can easily carry out basic maintenance in accordance with Eutect’s specifications. “Regular maintenance is absolutely necessary for a long-lasting, efficient use of our modules. But this does not mean that valuable production time is lost to the customer. With the staff training, the service cart and the tool set compiled according to our experience, we offer customers fast, professional maintenance that guarantees long-lasting and efficient use of the modules,” says Seibert.

Eutect launches online shop

The Swabian soldering specialist Eutect GmbH is starting its own online shop to provide customer with easy access to service aids and consumables, utilities, tools and wire feeders. Eutect is thus establishing new cooperations and is also extending its services to companies outside the electronics industry.

“In recent years, the demand for tools, spare parts and service aids and consumables has grown continuously. Taking this development into account we offer our customers and partners not only the classic, paper-based order but also the easy, convenient way of ordering online,” Matthias Fehrenbach, Managing Director of Eutect GmbH, explains the decision. No credit card or PayPal account is needed for the online shop. “Our customers can choose the goods and order them immediately without having to enter payment information. We process this order like any other order and the customer receives an invoice,” says Fehrenbach.

The Online shop offers customer necessary tools and aids, from a simple cleaning brush to a fully equipped tool cart. Furthermore, measuring tools and protective equipment for laser soldering machines maintenance can also be purchased. Consumables are a new product section. Fehrenbach would like to expand this area in the coming years, so the cooperation partners Emil Otto and Feinhütte Halsbrücke, which provides the Swabian machine manufacturer with selected cleaning media, flux pens and solders from ingots to solder wire, is the next step. “With both partners, we can offer the customer comprehensive advice on the best flux/brazing alloy combination. All cooperation partners manufacture their products themselves, which means that the customer receives first-hand technical information directly from a specialist. Together we can also combine new solder alloys, which are matched to the customer’s product, with the appropriate flux. To me this is a great benefit because the customer will receive everything from a single source,” says Fehrenbach. Additional consumables and cooperation partners will follow in the future. “We always come across products that fit well into our range and we would like to introduce and offer them to our customers,” confirms Fehrenbach.

In addition, the wire feeders developed by Eutect, as well as the corresponding controls, roll dispensers and solder wire feeders can be purchased in the online shop. “The offer is addressed to system integrators who build special machines outside the electronics industry on behalf of their customers. Such customers might work, for example, in the fields of car body construction, the textile industry, toolmaking or medical technology,” says Fehrenbach, who wants to strengthen his business as a supplier of modules beyond his core industry. “Many modules that we have developed can also be used in other non-Eutect plants without any problems. We would therefore like to make these in-house developments available to other machine manufacturers,” Fehrenbach continues.

Eutect recycles machines and modules

22. July 2020

When standard machines have become obsolete and are taken out of service, they are often resold as used equipment.

When standard machines have become obsolete and are taken out of service, they are often resold as used equipment. With customised machines this is a lot harder, as they are often configured too uniquely to be used for any other application. Eutect is now addressing this issue by recycling old systems and modules for new applications.

“We have decided to take systems built by us back instead of leaving them to the scrap metal dealer,” explains Matthias Fehrenbach, Managing Director of Eutect GmbH. The reasoning behind this decision is simple. Every system that Eutect supplies includes not only labour time but also material values that can be used for new projects. For example, the production cell, kinematic solutions but also soldering modules like solder nozzles, wire feeders or thermodes. “If these parts are still working, they can also be reused,” says Fehrenbach.

Eutect is currently converting a soldering system that has been used for years in the automotive supply industry. The machine still works and operates flawlessly, even if you look at the multi-shift operating time. But the traces of production are deceptive. The production cell is still in a stable, flawless condition and can be used for other machine concepts if the sustainability and cradle-to-cradle idea is applied. “This approach is based on a continuous and consistent recycling management,” Fehrenbach explains. The German chemist Michael Braungart and the US-American architect William McDonough came up with this approach, which is based on “cradle-to-cradle products” that can be continuously kept in technical lifecycles as “technical nutrients”.

After a general overhaul, the cell can be rewired, equipped with new modules and an updated control cabinet that is adapted to the new processes and thus made fit for new tasks. The wiring harnesses can no longer be used, but the soldering modules, robots or other kinematic systems integrated up to this point can be utilized in, for example, price-sensitive projects after being tested and overhauled. Some of the newly assembled machines are returning to the production cycle as rental machines. In addition to entire machines, Eutect also reworks individual modules. These are also thoroughly tested. After the reworking, the replacement of wear parts and an extensive functionality test, the modules are used for new projects or are first put into stock in order to be able to react quickly to inquiries. “We consider this approach to used systems to be important, because in times of scarce resources, climate change and an ever-increasing demand for sustainability, even as a small mechanical engineering company, we have to make our contribution,” confirms Fehrenbach.

Eutect and Inmatec agree on cooperation

The selective soldering specialist Eutect GmbH and the international market leader in the production of nitrogen and oxygen generators Inmatec GmbH are expanding their cooperation. In recent years, Eutect had already integrated Inmatec’s products into customer projects. Now Inmatec has become the official technology partner of Eutect GmbH.

“Not in every project our customers require soldering under nitrogen. It always depends on the production and the specifications, but in cases where this solution is requested, we have and will integrate the systems for self-producing nitrogen of Inmatec GmbH”, explains Matthias Fehrenbach, Managing Director of Eutect GmbH. As part of the many different soldering processes, inert gas is used to avoid oxides and to ensure high-quality soldered joints. This reduces complex and cost-intensive reworking and repairs. Furthermore, dross formation is avoided. “These measures not only produce improved soldered joints, increased cleanliness of the assemblies and a higher wetting speed, but also reduce the costs that can arise in connection with possible reworking,” Fehrenbach continues. In addition, the consumption of solder and flux can be reduced, thus enabling additional, significant savings.

Inmatec is the international market leader in the production of nitrogen and oxygen generators. Based in Herrsching am Ammersee near Munich, the company has been known for innovative technology “Made in Germany” for over 25 years. With the experience and know-how gained from more than 8,000 installed systems all over the world, the company develops and produces modern, energy-efficient and future-oriented solutions for the in-house production of nitrogen directly on site. Based on many years of experience in the electronics industry, Inmatec has also developed various products especially for the electronics manufacturing industry, which supply nitrogen in high purity at extremely low cost even for small quantities, including an easy-to-use, low-maintenance plug & play solution.

The nitrogen produced by generators meets the requirements for various soldering processes such as selective, wave or reflow soldering. An innovative and extremely efficient technology for extracting nitrogen from the ambient air helps to save costs for uninterrupted N2 supply to a considerable extent. The generators work by using the pressure load change technology. To do this, ambient air is fed at the required pressure into a valve block via an air compressor. This automatically ensures that the compressed air is alternately fed into two adsorption containers filled with a carbon molecular sieve. These alternately switch from filter mode to regeneration mode. Thus, in one container, oxygen as well as carbon dioxide molecules from the ambient air are adsorbed in the sieve, while the sieve regenerates in the second container under compressed air relief. The nitrogen thus obtained is fed into a product container.

By using a special hydrogen catalyst from Inmatec, the efficiency of on-site nitrogen generation can be drastically increased once again. The NKat ensures that generated nitrogen with a quality of 2.5 to 3.0 is enriched with small amounts of hydrogen, which react with the residual oxygen. Thus, the nitrogen is purified to a quality of 5.0 or even 6.0. The technical innovation makes it possible to produce a larger quantity of high-purity nitrogen, especially for THT production, with smaller, more energy-efficient air compressors with an air factor of 2.9 or higher.

When Inmatec systems are integrated into the Eutect plants, the process is controlled via an interface from the Eutect system controller EMI. “This allows the operator to control and monitor the nitrogen production process as well as the selective soldering processes via a single monitor and software. The training for this takes place during initial operation and handover to the customer. The complete system for nitrogen production will be developed together with Inmatec’s specialists and presented to the customer. This means that the customer receives the complete service from two partners from one source,” Fehrenbach emphasises. Furthermore, national and international customers are also supported by Inmatec around the clock in the event of maintenance and service.
