With the aim to make the production process in electronic manufacturing more efficient and to reduce production costs sustainably, SEHO extended its range of automation solutions in recent years.

The products range from board handling with conveyor systems to connect various machines and work places in production lines, buffer systems, turn stations, e.g. for changing the direction in manufacturing lines, lift stations, as well as transfer units and many more.
Work places made by SEHO are ergonomically designed and individually adjustable in height to be adapted to different operators. All of the connected stations such as buffers or conveyors adjust their height automatically.
In addition, a particular focus is on cobots and robots that are housed in a multifunctional production cell. This cell can be equipped individually so that the robot may take over several tasks: For component placement, for assembly and disassembly of component downholders, for loading and unloading of carriers, for precise positioning of boards for AOI and electrical tests, and for removal of reject parts.

Combined with the innovative soldering systems from SEHO, users benefit from complete solutions that are perfectly matched both technically and in regards to production flow. SEHO assists customers with creative ideas in the planning phase to best meet the individual production challenges, and constructs and manufactures the production line to provide customized automated solutions.

A production process free from defects, with every step being reproducible and traceable, is the target of quality assurance in electronics production worldwide. In many cases, manual rework processes are not allowed due to quality related reasons and cost issues. It is time consuming and cost-intensive, and hidden costs need to be considered, such as productivity rates or personnel training. Because of this, assemblies with defects often go through the production process a second time. However, in this case the entire board is exposed to the thermal load, not only the faulty solder connections, which can effect the overall product reliability.

An automated zero-fault production concept can provide a cost-effective solution. Automated process control and integrated automated rework enable a soldering process free from defects and completely documented.

ElectronTechExpo 2018 in Moskow turned out to be an outstanding success for SEHO. Together with the representative AssemRus, SEHO demonstrated the GoSelective-LS – the entry level selective soldering system that offers high-end technology such as an electrodynamic soldering unit and a complete range of automated process control features.

Electronics production continues to face new manufacturing challenges. In addition to high quality requirements at low production costs, there are an increasing number of product variants and the need for flexible reactions to fluctuation in demand. SEHO soldering systems offer the optimal solution when both matter, with high soldering quality and outstanding flexibility.

The GoSelective-LS selective soldering system is designed for stand-alone production of small and medium sized volumes with a very compact footprint. To ensure an ergonomic work flow and the shortest cycle times, the GoSelective-LS is equipped with a loading and unloading station for carriers up to 20” x 20”. Here, boards can be assembled in one carrier while a second carrier is being processed in the machine.

With the GoSelective-LS, all process steps are completely automated. The machine features a precise axis system that reliably positions the drop jet fluxer, preheat unit and soldering unit during the process. Depending on the requirements, the electro-magnetic soldering unit may be used for flexible mini-wave soldering processes, or can be equipped with a multi-nozzle tool for dip soldering with short cycle times.

SEHO North America, Inc. highlighted a full line of market leading soldering systems at the IPC APEX EXPO 2018.

The new SelectLine-20 selective soldering system features both the highest flexibility and highest production volumes with five stations working in parallel, for assemblies up to 20” x 20”. Moreover, the system is able to process long boards up to 59” in length, depending on the application. Its outstanding modular design and innovative technical details ensure clear cost benefits.

The SelectLine-20 machine concept incorporates a fluxer station featuring the highest precision with automatic position correction and fiducial recognition. To increase production volumes, several fluxer heads can be installed. The distance between the fluxer heads can be programmed through the software to ensure maximum flexibility.
The preheat area provides various stations that can be individually equipped with a convection module or quartz heaters for bottom-side heating as well as infrared heaters for top-side heating.
Highest flexibility also is achieved in the soldering area. The high performance electro-magnetic soldering units can be used for flexible miniwave soldering as well as for multiwave soldering processes to reduce cycle times significantly. Additionally, the system features SEHO’s unique Synchro mode that nearly doubles production volume without major investments.

As a particular highlight, the SelectLine-20 can be equipped with SEHO’s award-winning additional processes: An automated selective brush station to remove any residues after the soldering process and an AOI station for immediate inspection of solder joints. The advantages are obvious: Safe and reliable processes on the one hand, and reduced overall production costs on the other hand, without the need for extra floor space.

All of SEHO’s selective soldering systems feature 100 percent process control, with flux quantity control, wave height control and automatic tool measurement, process visualization, mcServer and many more value-added features. In doing so, they provide uncompromised superior accuracy and soldering quality. Additionally, SEHO’s automatic ultrasonic nozzle cleaning function guarantees reliable processes and maximum machine availability.

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 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 can now also 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.

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.

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.

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.
