Heike Schlessmann — Wed, 14 Oct 2026 07:24:42 +0000

An anniversary is a good time to look back. But it is even better to look ahead. That is why, to celebrate SEHO’s 50th anniversary, we are introducing a special edition of our selective soldering system SelectLine: The SelectLine-R.

“R” stands for “Ready” and sums up the concept: The SelectLine-R comes in a clearly defined, optimally tailored configuration, is available quickly, and is offered at an attractive anniversary price for a limited time.

Tradition meets high-tech: This anniversary model also makes a visual statement. The SelectLine-R is built with orange side panels as a tribute to the SEHO machine color from the early years. For those who prefer a more classic look, the machine is, of course, also available in today’s SEHO blue.

The Highlights of the SEHO SelectLine-R

Ready to produce

The SelectLine-R is designed for demanding high-mix, high-volume applications. Its features combine flexibility with high production capacity and cover a wide range of manufacturing requirements.

Ready for more output

Two soldering units and parallel processes ensure short cycle times and high throughput. The SelectLine-R is designed with this in mind: it becomes operational quickly, without a lengthy configuration phase.

Ready for any production mix

Whether you are producing small batches with a wide variety of products or high-volume series, the SelectLine-R adapts to your product mix. The miniwave ensures maximum flexibility for changing products and varying soldering tasks. The multiwave delivers when short cycle times and high production volumes are required.

Ready for reliable processes

To ensure reproducible soldering results, the SelectLine-R combines several SEHO technologies that are designed to work together. These include the gradient-controlled preheating process and automatic ultrasonic cleaning of the solder nozzles. Integrated process monitoring – such as flux function monitoring and automatic wave height control using the SEHO cross sensor – ensures a stable process.

Ready when you are

The key advantage of the SelectLine-R lies in its predefined configuration: You benefit from short delivery times and a particularly attractive price. It is ideal for companies looking to expand, modernize, or build new selective soldering capabilities on short notice.

And yet the system remains flexible enough to meet future requirements: Many of the SelectLine-C’s options and add-on modules can also be added or retrofitted at a later date.

SEHO SelectLine-R: Ready when you are!

A high-end system to celebrate our anniversary: powerful, available quickly, and offered at a special price for a limited time.

Innovation with Substance: SEHO Once Again Awarded with BSFZ Seal

Heike Schlessmann — Mon, 06 Jul 2026 11:00:02 +0000

Research and development have always been a central part of SEHO’s corporate philosophy. From the very beginning, SEHO has consistently invested in new technologies and driven numerous pioneering developments for electronics manufacturing – both through its own research and development work and in cooperation with strong partners from industry and research.

This commitment continuous to shape us today. Every year, we invest around 8 % of our turnover in research and development, placing us well above the industry average. Our activities focus on future-oriented technologies as well as the continuous advancement of our existing systems. After all, for us, innovation means more than developing new ideas – it means turning them into concrete solutions that provide measurable benefits for users in their daily production environment.

The fact that this is the right path is also reflected in the BSFZ Seal, which SEHO has received for several years now. The seal is awarded be the German Research Allowance Certification Office (BSFZ). It confirms, that a company conducts research and development and may visibly demonstrate its innovation competence to the outside world.

For SEHO, the BSFZ Seal is therefore not only an award, but also a confirmation of our continuous commitment: We take technologies further, question existing processes and develop solutions that make electronics manufacturing more efficient, more reliable and ready for the future.

We are proud of this – and at the same time, it motivates us to consistently continue on this path. With a passion for technology, a strong development team and the clear goal of actively shaping the electronics manufacturing of tomorrow.

SEHO Wins 2nd Place at the productronica Innovation Award 2025!

Heike Schlessmann — Mon, 01 Dec 2025 13:19:38 +0000

Thermographic monitoring of flux application sets new standards.

We couldn’t be more proud: Our technology for process-integrated, inline-capable monitoring of flux application, developed in collaboration with SIEMENS AG, Foundational Technologies Berlin, was awarded second place in the Future Markets Cluster at productronica 2025. This award is impressive confirmation of how relevant and forward-looking this development step is for electronics manufacturing.

A breakthrough for a process step that was previously impossible to monitor

The application of flux in wave and selective soldering is a key process step, but one that has been difficult to control until now. Too little flux leads to soldering errors such as incomplete penetration or cold solder joints, while too much can cause residues that can impair the function of the assembly.
Previous monitoring methods are generally based on random sampling or purely functional checks of the fluxer. They therefore do not provide any information about the actual application on the individual printed circuit board.

This is precisely where the new technology comes in: For the first time, it is possible to test every printed circuit board inline and automatically. Not only is the amount of flux applied monitored, but also its exact position.
The system utilizes the physical effect that heat is locally extracted from the assembly when the solvent in the flux evaporates. This makes wetted areas appear cooler.
A thermal imaging camera captures this pattern immediately after fluxing and evaluates it intelligently. The analysis is based on a reference model, either a thermographic image or a CAD-based digital twin.

The result is a reliable, highly accurate decision as to whether an assembly is correctly fluxed and approved for the soldering process.

More quality, more efficiency – and the path to autonomous manufacturing

The practical implications are enormous: Incorrect flux application is detected immediately rather than only becoming apparent after soldering, and the corresponding assemblies can be automatically removed from the production line.
This reduces waste, prevents unnecessary rework, and increases process reliability throughout the entire production flow.
At the same time, the technology forms the basis for future AI-supported optimization in real time. The thermographic data collected can be used in the future to automatically adjust process parameters and implement adaptive, self-regulating manufacturing.

As a result, the system not only closes a long-standing gap in process monitoring, but also opens up new possibilities for quality, efficiency, and automation, especially in areas with high requirements.

An award that stands for a strong team

This award is a special achievement for us at SEHO, as it demonstrates what can be achieved when expertise in manufacturing technology, software development, and research come together.
We would like to thank everyone involved for driving this project forward with passion and an innovative spirit, and of course we would like to thank the jury of the productronica Innovation Award for this outstanding recognition.

SEHO Nominated for the productronica Innovation Award 2025!

Heike Schlessmann — Tue, 21 Oct 2025 08:52:13 +0000

We are excited and proud that SEHO has been nominated for the productronica Innovation Award 2025 with its latest development for process-integrated monitoring of flux application in wave and selective soldering processes!

Automated control of flux application – a milestone in electronics manufacturing

With the inline-capable, process-integrated control of flux application, fully automated and seamless monitoring of this critical process step in electronics manufacturing is now possible for the first time. Developed in collaboration with SIEMENS AG, Foundational Technologies Berlin, the solution sets new standards in soldering process monitoring.

The new solution is based on thermographic detection of flux application and analysis of wetted areas in terms of their location and extent. Automatic decision logic evaluates the quality of the application and only releases assemblies for the soldering process if they meet the requirements.
Additionally, the system paves the way for AI-driven process optimization in real time, marking a significant step towards the smart factory.

Our Highlights at productronica 2025

Selective Soldering

The new PowerSelective-HD offers the perfect combination of flexibility, energy-efficiency and process reliability.
A new, innovative cluster preheating concept specifically heats only the relevant assembly areas, significantly reducing energy consumption. The new, flexible soldering unit accommodates several multi-nozzle tools simultaneously, thereby significantly increasing throughput. An eco mode ensures resource-saving operation, while additional integrated processes such as the selective brushing system and THT-AOI system offer maximum process reliability.

Wave Soldering

Increased efficiency and intelligent process control are also the focus in wave soldering. The segmented flux application enables potential savings of up to 50 % depending on the assembly layout: Only those areas of the assembly where solder joints are actually located are applied with flux. This reduces consumption and maintenance requirements, and also has a positive effect on the process. In addition to the energy savings achieved in the preheating area with innovative pulsar emitters, the newly developed tunnel insulation also significantly reduces resource consumption.

THT Inspection

AOI made easy: The SEHO AssemblyCheck component placement inspection system and the SEHO PowerVision THT-AOI system guarantee the high quality of your products right from the start!
