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.

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.

Automatic Nozzle Cleaning: Advantages for Efficiency and Quality

Heike Schlessmann — Mon, 02 Jun 2025 09:29:54 +0000

In electronics manufacturing, the quality of the soldering process is critical to the functionality and reliability of the finished assemblies. The solder nozzles play a particularly important role in the selective soldering process, as they are the key element between the solder and the product. “Precision” is the key word here.

However, dirty or poorly maintained nozzles can have a serious impact on the quality of the solder joints and the entire production process since they can lead to uneven or insufficient solder application, causing incomplete or poorly wetted joints.

Continuous care and maintenance of the solder nozzles is therefore essential. Although manual cleaning is a common method, it can be associated with various disadvantages that impair the production process in electronics manufacturing.

Compared to manual cleaning processes, automatic ultrasonic cleaning of solder nozzles offers numerous advantages that affect both the quality and efficiency of the selective soldering process.
The consistency and precision of the automated ultrasonic cleaning reduces soldering defects, minimizes downtime, and extends the nozzle life. It also reduces maintenance and saves money. Because the process runs independently of the operator’s experience, residues are reliably removed, and the nozzles are optimally prepared for the next use.

In an increasingly competitive industry, the automation of cleaning can be a critical factor in improving production processes and a company’s long-term competitiveness.

Automatic ultrasonic cleaning for mini wave solder nozzles is available for many SEHO selective soldering systems. Just contact us.

SEHO SelectLine-C: Increase Production Volume without Large Investment

Heike Schlessmann — Fri, 27 Sep 2024 09:36:53 +0000

Typically, to increase production volume in selective soldering processes, additional soldering units need to be added, or the machine must be equipped with a dual conveyor to allow parallel processing of boards. These measures, of course, are related to large investment.

Increase production volumes without large investments using the Synchro or SmartSplit production mode of the SEHO SelectLine-C.

Synchro and SmartSplit are software features that coordinate and control the production flow.
While Synchro is optimized for batch production, SmartSplit ensures highest production rates in mixed operation, thus allowing high mix – high volume production in selective soldering processes.

In both production modes, the soldering job is automatically distributed among the available process stations that are integrated into the individual machine. As a result, Synchro and SmartSplit enable the production volume amost to be doubled – without large investments.

All parameters required to use the SelectLine-C in Synchro or SmartSplit production mode can be easily programmed using SEHO’s offline teach progam. Creating soldering recipes is comfortable and quick. For an assembly, only the overall soldering task needs to be programmed. The software automatically divides the soldering task among the available process stations and calculates the fastest route to minimize handling and processing time.
