SEHO to Present New Developments Leading to Higher Productivity at SMT/Hybrid/Packaging 2014

Apr 07, 2014

SEHO SelectLine

SEHO SelectLine

SEHO Systems GmbH, a worldwide leading manufacturer of automated soldering machines and customer-specific systems, offers innovative solutions designed for more productivity in electronics manufacturing.  SEHO will present these new developments in booth 9-209 at SMT/Hybrid/Packaging 2014, scheduled to take place May 6-8 in Nuremberg, Germany.

Higher Production Volume

The patented Synchro concept, an innovative highlight of the new selective soldering system SEHO SelectLine, guarantees maximum throughput. Typically, to increase production volume, additional soldering modules need to be added, or the machine has to be equipped with a dual conveyor to allow parallel processing of boards. These measures, of course, are associated with a large investment in equipment. The Synchro concept is an intelligent software feature that coordinates the soldering process for two PCBs in such a way that the total throughput is nearly doubled without the need for significant investment. The assemblies can enter the soldering area independently and are not linked to the same cycle. With the new Synchro concept, cycle times can be reduced by nearly 50%.

More Machine Availability

Innovations from SEHO focus on one point: to increase the system's productivity. This also includes reduction of maintenance times.

The automatic ultrasonic cleaning for wetted miniwave solder nozzles is a unique new feature, patented by SEHO.  Previously, cleaning had to be done manually using aggressive chemicals, but now the machine can complete this in an automatic and environmentally friendly way.  With the ultrasonic cleaning unit, the liquid solder is set into oscillation which then gently cleans the surface of the nozzle. Using the existing inert atmosphere, the surface is completely re-wetted and the solder nozzle is restored to its original state. Besides a longer lifetime of the solder nozzles, this unique feature provides an absolutely stable process and significant time savings in terms of maintenance.

Another new feature for conventional wave soldering systems reduces maintenance, thus increasing productivity. An innovative process gas cleaning system actively extracts the contaminated process gas from the tunnel and ensures, using up-to-date, water-supported cyclone technology, an effective condensation of suspended particles and dirt. Afterwards, the cleaned process gas is returned behind the soldering area without any loss of nitrogen atmosphere.

Besides remarkably higher machine availability, this new system can also positively influence the process as the cooling down of assemblies occurs faster.

More Integrated Solutions

Selective soldering systems from SEHO not only feature highest precision and flexibility, they also provide outstanding integrated solutions for process control.

With the machine communication software mcServer, selective soldering processes can be traced completely and are ready for the requirements of Industry 4.0. This software feature allows comprehensive control of the soldering process with real-time access to all connected machines that may be installed in different production sites worldwide.

A further unique feature is the possibility to integrate an AOI system for solder joint inspection directly after the soldering process.


Since its foundation in 1976, SEHO has become the worldwide contact partner whenever soldering is involved. Company solutions are based on performance, flexibility, efficiency and technical progress. SEHO’s business activities and production organization are oriented according to the principles of sustained future-compatible development and production of machines. As a result, all applicable environmental standards are complied with meticulously. With its systems, the company provides customers with a sustained and resource economizing production facility. It continuously develops its technology in order to provide customers with a competitive advantage.For further information about SEHO, please stop by booth 9-209 at SMT Nuremberg, or visit www.seho.de
