SEHO Systems GmbH is pleased to announce that it was awarded a 2017 Global Technology Award in the category of Soldering – Selective for its Integrated Additional Processes in Selective Soldering Systems. The award was presented to the company during a Tuesday, Nov. 14, 2017 ceremony that took place during productronica in Munich, Germany. The SEHO PowerSelective and SEHO SelectLine selective soldering systems can be equipped with an automated selective brush system and an AOI system for immediate automatic cleaning and inspection of solder joints directly after the soldering process. All processes are integrated in ONE machine.

The ability to reduce production costs while maintaining consistently high quality is essential for electronic production. Solder balls represent a soldering defect that is considered particularly critical. There are numerous reasons for the formation of solder balls in selective soldering processes, ranging from poor process setup, up to the material used, such as the solder resist of the PCB. Solder balls can cause shorts leading to complete failure of the assembled product. Other typical soldering defects such as solder bridges, insufficient wetting or open solder joints also can severely affect the product quality and reliability.
Considering that manual cleaning or repair processes after soldering are not only expensive and time-consuming but also provide poor reproducibility, the target, therefore, is an automated and fully controlled zero-fault process.

With SEHO’s Integrated Additional Processes in Selective Soldering Systems, all processes – selective fluxing, preheating, soldering with selective mini-wave, multi-nozzle or even conventional wave soldering, selective brushing, AOI and cooling – can be performed in parallel for different boards. Therefore, the additional processes do not influence the cycle time. The advantages of the additional functions are obvious: Safe and reliable processes on the one hand, and reduced overall production costs on the other hand, as the integrated additional processes use the handling units of the soldering machines (conveyors, axes, grippers etc.) and in addition they do not require extra floor space.

Premiering in 2005, the Global Technology Awards program is an annual celebration of product excellence in electronics surface mount assembly. Premier products based on the finest examples of creative advancement in technology are chosen by a distinguished panel of industry experts.

Approaching the Smart Factory with Communicating Machines



SEHO focused on the complete networking of manufacturing lines at productronica 2017. Further highlights at the SEHO booth were presented from the field of wave soldering and reflow technology.

Instead of single machines, SEHO presented a complete production solution that provided users with ideas for optimizing their own manufacturing processes. All machines in the production line were linked with the SEHO mcServer, the machine communication server from SEHO.
The production solution continuously exchanged data – from placement control, to a flexible selective soldering process with automatically controlled removal of solder balls and integrated optical inspection –  to intelligent handling systems and automatic separation of defect assemblies by means of a robot.

mcServer allows complete monitoring of all integrated processes and machines, and provides real-time information from systems – including those installed at different production sites worldwide. Additional functions effectively support the operator, such as easy generation of production statistics, continuous traceability of production parameters for each product serial number, automatic monitoring of maintenance cycles or automatic notification in case of machine failures. Collected process and machine data are made available for other applications, such as customer networks or MES systems. Also, integration in Pulse or Hermes software architecture is easily possible.

High mix, and simultaneously high volumes, are possible with the new features for wave soldering systems. A new preheat concept from SEHO allows minimum distances between the boards, even with very different thermal requirements. In the soldering area, an innovative dual solder pot concept based on electro-magnetic waves allows product changeover within seconds.

A new development from the field of reflow soldering reduces maintenance times and optimizes energy consumption. Because of its innovative details, the SEHO MaxiReflow has won several technology awards in the past. As an alternative to the proven process gas cleaning system with cyclone technology, this innovative reflow system now also can be equipped with a new pyrolysis unit. What is special about this feature: the pyrolysis unit is completely integrated in the heating chamber which completely excludes any loss of energy.

The SEHO team would like to thank all visitors for a great productronica 2017!

You did not have the chance to see us during the show? No problem … all new machine features are available in our Technology Center and we are looking forward to welcome you there!

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.

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.
