How does induction soldering work?

In induction brazing, an induction coil generates an alternating electromagnetic field. This induces electric currents in the conductive workpiece, thereby generating heat. The geometry and positioning of the inductor allow the energy input to be precisely concentrated on the desired brazing joint. Temperature, time, position and energy input can be controlled according to the specific process requirements.

What are the advantages of induction brazing?

The key advantages include rapid, contactless energy transfer, short heating times, high energy efficiency, and precise, reproducible process control. As the heat is generated specifically within the brazing zone, adjacent areas are protected. Induction brazing is also particularly well suited to automated manufacturing processes.

For which applications is induction soldering suitable?

Induction brazing is particularly suitable for applications in which electrically conductive components need to be heated quickly, reproducibly and locally. The process can be used, for example, for electrical contacts, connection components, power electronics and other demanding assembly and joining tasks.

Which materials can be soldered using induction?

In principle, the process is suitable for electrically conductive materials. How well a specific component can be heated inductively depends, amongst other things, on the material, geometry, electrical and magnetic properties, as well as the frequency used and the inductor geometry. For this reason, the induction process is tailored to the specific brazing application.

How is the temperature controlled during induction brazing?

With EUTECT, pyrometric temperature control can be utilised. This involves measuring the temperature without contact and using the data for controlled process management. In conjunction with defined time, temperature and position profiles, the heat input can be precisely tailored to the specific soldering task.

Why is induction brazing suitable for temperature-sensitive components?

The induction field can be precisely focused on the relevant area of the solder joint. This means that the entire component does not need to be heated. The localised and rapid heating can reduce the thermal stress on adjacent components.

Induction soldering systems from EUTECT

The EUTECT induction soldering process offers numerous advantages over other soldering processes:

Energy efficiency: As the heat is generated directly in the material, the energy loss is reduced. This makes the process more efficient. The very short heating times also help to reduce energy requirements.
Precision: The induction soldering process applies the heat specifically to the soldering point and thus protects neighbouring areas. This is particularly advantageous for sensitive electronic components.
Speed: As heating takes place in a matter of seconds, process times can be shortened, productivity increased and processing times in production reduced.
Cleanliness: Contamination and vapours are minimised compared to other processes. This ensures a clean working environment and requires less post-processing.
Repeatability and automation: Process parameters such as temperature, time and energy supply can be precisely controlled and regulated in EUTECT systems. This ensures consistent quality for each individual soldering process. The process can also be easily integrated into automated production lines.
