Induction soldering

At the Induction soldering 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 solder joint. Temperature, time, position and energy input can be controlled according to the specific process requirements.

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 soldering zone, adjacent areas are protected. Induction soldering It is also very well suited to automated manufacturing processes.

Induction soldering It 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.

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.

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.

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.

EUTECT induction brazing processes can be combined with different forms of solder supply. In addition to solder wire, these include, for example, solder pastes, SRS lead rings and preforms can be processed. This allows the solder supply to be tailored to the specific application and process requirements.

For wire-guided applications, the EUTECT Sensitive Wire Feeder (SWF) be used. The regulated solder wire feed ensures a controlled supply of solder, thereby facilitating reproducible process control.

Induction soldering provides good conditions for a high degree of repeatability, as key process parameters such as temperature, time, position and heat input can be defined and monitored. In automated systems, this enables reproducible process conditions to be established for successive brazing operations.

Yes. As the energy is directed specifically at the workpiece or the relevant soldering zone, there is no need to heat large assemblies or process areas. This is combined with short heating times. As a result, Induction soldering offer energy-related advantages over heating methods that operate on a less local scale.

Yes. Induction soldering is ideally suited to automated manufacturing processes. Process parameters can be defined, monitored and executed in a reproducible manner. EUTECT induction brazing modules can also be used with various Wire feed, dispenser and automation modules can be combined and integrated into bespoke manufacturing solutions.

Yes. The modular EUTECT systems can be configured to meet specific production requirements and integrated into automated production lines. Among other things, this allows for Handling, solder feeding, process monitoring and control be adapted to the existing production environment.

Key parameters include, amongst others, frequency and power, the duration of energy input, the temperature profile, the distance and position of the inductor, the inductor’s geometry, material properties, and the type and quantity of solder used. To ensure a stable process, these factors must be tailored to the component and the solder joint.

The induction coil, or inductor, has a significant influence on where and to what extent energy is coupled into the component. The geometry, distance, positioning and field concentration are therefore tailored to the specific solder joint. A design tailored to the specific application enables targeted heat input and contributes significantly to process stability.

Process quality can be ensured by recording and monitoring relevant process parameters. At EUTECT, the equipment available for this purpose includes, amongst other things, a high-speed pyrometer control system and the EUTECT Recording Inspection Camera (ERICa) and the Solder Guard are available. The systems thus support controlled and traceable process management. EUTECT

Yes. EUTECT systems are designed to ensure transparent process control and support 100 per cent traceability. Process parameters can therefore be used for quality assurance and traceability.

Both methods enable targeted, contactless energy transfer, but are based on different physical principles. In the case of Induction soldering Heating takes place via electromagnetic induction within the conductive material. In the case of Laser soldering In contrast, energy is introduced into the joint via laser radiation. Which method is more suitable depends, amongst other things, on the material, component geometry, accessibility, cycle time and process requirements.

Induction soldering This is particularly useful when rapid, locally confined and reproducible heat input is required. This applies in particular to automated applications with high demands in terms of process control, cycle time, energy efficiency and repeatability.
