SEHO Expert to Discuss Resource & Cost Efficient Wave Soldering at SMTAI

SEHO Systems GmbH is pleased to announce that Arne Neiser, Product Manager, will present “Resource-efficient and Cost-effective Wave Soldering – Plasma Fluxing, Pulsar Preheating and Lead-free Low Temperature Soldering” during the Spotlight Series of the technical conference at SMTA International on Wednesday, Sept. 20, 2017 at 8 a.m. The SMTA International Technical Conference is scheduled to take place Sept. 17-21, 2017 at the Donald E. Stephens Convention Center in Rosemont, IL.

In this paper, the latest technologies for wave soldering are presented, along the process chain. Starting with plasma fluxing, an alternative to liquid based fluxing is described, that offers low cost (100 percent solids) while being environmentally friendly (no VOCs). The latest soldering results using this technology will be discussed and basic conditions when this process can be efficiently introduced into a factory environment will be presented.

Concerning preheating, previous heaters like infrared heaters were not usable for mixed production without long delays for switching between different settings. To resolve this limitation, pulsar heaters can be used for preheating that offer a quick response while having a radiation wavelength that is very well absorbed by PCB materials. Using these preheaters, high mix and high volume production is possible within the limits that were identified by test series using massive and slim assemblies.

Additional methods will be discussed to even further reduce power consumption. For further information, please visit SEHO in booth #1325 at SMTA International.

Successful Premier of InnovationsForum México

More than 250 industry professionals came together at Universidad Panamericana in Guadalajara for the first InnovationsForum México. SEHO participated with an exciting lecture on zero-fault production processes, presented by Guillermo Maldonado, Director of STE Latinoamerica, SEHO’s partner in Mexico.

A production process free from defects, with each production step being reproducible and traceable is the target of quality assurance in every electronics production worldwide. In many cases manual rework processes are not allowed, they are almost non-reproducible and often cannot be performed with the required high quality. In addition, manual rework is time-consuming and cost-intensive, and hidden costs such as productivity rates or staff training need to be considered. Because of these major issues assemblies with defects often go through the production process a second time. However, then the entire board is exposed to the thermal load, not only the faulty solder connections.

Precisely at this point the zero-fault production concept from SEHO comes in:
Automated process control and integrated automated rework enable a soldering process free from defects and completely documented.

100 % Process Control at SMT/Hybrid/Packaging

SEHO Systems GmbH, a worldwide leading manufacturer of complete solutions for soldering processes and automated production lines, will focus on automatic process control in hall 4, stand 129 at the upcoming SMT/Hybrid/Packaging show, scheduled to take place May 16 – 18, 2017 at the Messe in Nuremberg, Germany. The selective soldering system SEHO SelectLine-C has been even further optimized.

SEHO will introduce its new cross sensor at the exhibition that takes over several functions. On the one hand, the wave height is precisely controlled. The measurement is made touchless directly at the solder nozzle and it is fully independent from the solder alloy used. In addition, the cross sensor is also used for automatic tool measurement: diameter, height and mounting position of the solder nozzle are automatically controlled, thus excluding potential operator errors.
Also new, being introduced for the first time, is an automatic nitrogen flow quantity control.

SEHO is the only manufacturer worldwide which offers the opportunity to integrate additional processes directly into its selective soldering systems. This includes, for example, a brush system for solder joint cleaning or an AOI system for automatic detection of soldering defects. The benefits are obvious: no additional floor space is required in the production area. At the same time production costs will be reduced as the entire board handling is performed by the axes systems that are integrated in the selective soldering machine anyway.
By adding an intelligent handling concept from SEHO, assemblies that have been identified as defective can automatically be removed from the production line.

The new process control functions ideally supplement already existing features such as flux quantity monitoring, monitoring of the nitrogen quality or the automatic position and z-height correction thus ensuring a 100 % process control.

Participants from all over the world

Nearly 50 participants from more than 25 countries, including Japan, China, Mexico and Brazil, came together for SEHO’s International Sales Meeting. SEHO Systems GmbH is one of the worldwide leading manufacturers of end-to-end solutions for soldering and automated production lines. At the center of the 2-day event were the latest technical developments, future technology trends and the company’s global sales strategy.

SEHO has experienced an above-average growth in recent years, mainly in America and Asia. “Even within the European internal market we have successfully acquired new customers and further extended our systems for existing customers,” outlined Managing Director Markus Walter in his welcome address. The product segments with the strongest growth rates included wave and selective soldering units and automation technology – an area that SEHO significantly expanded in recent years. It goes without saying that growth is linked to investment. SEHO now employs a workforce of over 200 and trains qualified staff in more than 10 professions. A new warehouse building (in the Reinhardshof area) was recently put into operation to accommodate additional production space for SEHO’s Kreuzwertheim site, and a further expansion of the manufacturing space is already in the planning stages.

During the International Sales Meeting, SEHO’s sales partners were presented with the latest technical innovations and had the opportunity to test these in a number of workshops. The focus was mainly on new developments in automatic process control, which are of particular interest in view of Industry 4.0. Another highlight included automation technology: with creative solutions for processing electronic modules, SEHO skilfully translated the corporate strategy of providing “everything from a single source” into action.
During round-table debates and an evening event, the international guests were able to share experiences with peers from all over the world and – together with SEHO – to pave the way for a common successful future.

Another positive result was a highly motivated sales team that left the SEHO headquarters in Kreuzwertheim with many innovative ideas and new potential. “SEHO is a global player who, in recent years, has successfully evolved from a soldering system manufacturer into a system supplier. Events such as these are important for us to further strengthen international cooperation efforts with our partners, to discuss future requirements in different countries and to ensure that we offer optimum support to our world-wide network of customers,” explains Markus Walter.

SEHO Technology Days in Mexico

The premiere of the SEHO Technology Days in Mexico which took place in Guadalajara and Queretaro, two major Mexican centers of electronics production, at the end of February was a full-on success. In cooperation with STE Latino America, SEHO – a worldwide leading manufacturer of complete solutions for soldering processes and automated production lines – held two rounds of seminars which were attended by a great number of users, mainly from the automotive sector. STE Latino America is an expert partner for electronics productions in Mexico with extensive, long-term experience in the relevant processes and SEHO systems engineering.

“We know exactly what electronics manufacturers in Mexico require”, explains Guillermo Maldonado, Managing Director of STE Latino America. “Through the framework of the Technology Days we wanted to offer an opportunity to discuss the current developments with other experts and to find approaches for optimizations in their own production environment.” Exciting lectures and intense discussions addressed everyday requirements in electronics production, but also focused on the latest in system developments and technologies of the future.

A focal point of the Technology Days in Mexico were the challenges of high-mix/high-volume production which is becoming more and more common, especially in the automotive industry. Dr. Andreas Reinhardt, Director Research and Development at SEHO, pointed out that a high product mix and high-volume production need not be mutually exclusive. One of the key aspects to ensure cost-efficient goods at a consistently high quality is top equipment productivity. What counts is how flexible systems engineering is responding with regards to the production of different goods in both small and large batch sizes in the smallest possible production area, using a variety of starting materials without conversion.

For fluxing in wave soldering applications, SEHO developed a highly flexible plasma technique that supports the efficient production of varying volumes. A significantly lower flux consumption and low maintenance requirements also help to reduce the total production cost.

Ludger Brosch, Head of Design for Wave and Reflow Soldering, presented an innovative preheat approach on the basis of pulsar emitters which facilitates the cost-efficient production of large series as well as lot sizes of 1. This is realized through a particularly high degree of efficiency thanks to greatly responsive heating elements in combination with targeted activation. Configuring emitters individually instead of using entire segments helps to accomplish shortest assembly distances. In small to medium volume production, energy consumption can be reduced by 30 – 50%.

A large number of product variants with different thermal requirements is another challenge in SMD production. By means of a new, emission-free quick extraction method, SEHO reflow systems are able to reduce the temperature level in the soldering system within a very short period of time, for example to facilitate switching from a soldering to an adhesive profile.

The reliability, traceability, and documentation of the production process is gaining in importance especially in the automotive sector, but also in other industries, including THT production. To meet these requirements, SEHO has developed an automated optical inspection system that is specifically designed for the inspection of THT solder joints and can be integrated directly into SEHO selective soldering units. During the technology seminars in Mexico, users discussed the versatile applications of the AOI system SEHO PowerVision, including its use in automatic production control.

Specialist knowledge that can be implemented directly into a company’s manufacturing processes, intense debates about future trends in electronics production, and the exchange with experts describe the results of a successful series of SEHO seminars in Mexico, which will surely soon be followed by similar events.
