Solution competence

EUTECT has built up this expertise primarily through a combination of process know-how, years of experience, system integration, understanding of materials and a high degree of specialisation in demanding soldering applications. This experience is particularly crucial in the fields of power electronics, automotive, medical technology and industrial electronics.

The following reasons for this expertise should be emphasised:

In-depth process understanding in selective soldering

EUTECT not only develops machines, but also complete soldering processes. In high-temperature soldering, parameters such as temperature profiles, heat input, wetting, flux behaviour and thermal load are particularly critical.

The deep understanding of the process results in a multitude of added values for the customer:

Precise temperature control
Controlled heat input for component protection
Reliable, stable, controlled processes suitable for mass production, designed for demanding soldering tasks
Reproducible results for complex assemblies
Low service and maintenance costs for modules and machines

Theses EUTECT has built up expertise in 30 years of process development for a large number of customers and application areas.

Focus on demanding applications

High-temperature brazing is primarily required where standard processes are not sufficient:

Power electronics
Applications with high thermal load
Sensors and industrial electronics
Assemblies with high reliability requirements

EUTECT works specifically in these high-end segments. This results in in-depth specialised knowledge and understanding of the customer application.

In-house development of soldering modules and process hardware

A key factor in being able to realise such customer requests is the in-house development of core technologies:

Mini-shaft, titanium mask, workpiece carrier and nozzle technology from a single source
Precise heating and temperature control
Regulated, specific, inductively pumped high-temperature soldering modules
Modular process integration in automation systems
In-house software development

This enables EUTECT to offer the entire process with all components from a single source.

Holistic approach instead of selling machines

EUTECT supplies functioning, validated soldering processes and machines that can be integrated into the customer's existing production structures without major commissioning work.

This includes:

Process development and evaluation
Material, solder and flux selection
Component analysis
Preliminary tests and process qualification
Stable series processes on delivery

This holistic approach is particularly important for high-temperature soldering in order to develop a reliable, efficient process for the customer.

Modular automation and integration expertise

High-temperature processes often have to be integrated into complex production lines.

EUTECT combines:

Soldering technology
Automation solutions
Software control
Process control and monitoring

This enables stable inline processes even with demanding thermal requirements.

FAQs

What is high-temperature brazing and when is it used?

High-temperature brazing refers to brazing processes with temperatures typically exceeding 350 °C, depending on the brazing alloy used. It is used when assemblies need to withstand high thermal or mechanical stresses, for example in power electronics, electromobility or in applications with elevated operating temperatures and long service life requirements.

What are the advantages of high-temperature soldering in electronics manufacturing?

High-temperature brazing enables brazed joints with high thermal and mechanical stability. The use of high-melting-point solder alloys improves creep resistance and reduces the probability of failure under thermal cycling. This is particularly relevant for long-life assemblies subject to high current densities and cyclic temperature stresses.

Why is process expertise crucial in high-temperature brazing?

During high-temperature soldering, components and printed circuit boards are subjected to high thermal gradients. Precise control of temperature profiles, heating rates and wetting time is essential to prevent delamination, component damage or insufficient wetting. EUTECT uses validated process windows to ensure stable mass production processes.

Which applications require high-temperature brazing?

Typical applications include power semiconductors, power supplies, electric motors and assemblies in automotive and industrial electronics. High-temperature soldering is essential, particularly in cases involving high operating temperatures, high current loads or safety-critical functions, in order to ensure long-term reliability and mechanical stability.

How can stable and reproducible soldering processes be achieved?

Reproducible processes require defined process windows, closed-loop control systems for temperature and solder flow, and continuous process monitoring. In-line systems with a nitrogen atmosphere and validated parameters, such as those used by EUTECT, ensure consistent quality in series production.
