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.
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.
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.
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
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.
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.
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.
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. 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Induction soldering is particularly suitable for delicate, miniaturised and precision assemblies with high quality requirements.
The SWF detects deviations in real time and adjusts the wire feed. This minimises errors and stabilises processes.
The SWF is a force- and travel-controlled wire feed system. EUTECT utilises this technology to ensure maximum process reliability.
The wire feed determines the amount of solder and the positioning. Precise feeding ensures stable processes and reproducible solder joints.
Induction soldering enables precise, contactless and locally confined heating. This improves process control and reduces thermal stress.
Induction soldering generates heat directly within the material through electromagnetic induction. This allows the soldering joint to be heated precisely, whilst adjacent components are spared.
Reliable cooling improves process stability, extends the service life of the coil and ensures reproducible results in serial production.
Copper, aluminium and nickel react differently to inductive heating. The induction coil must therefore be precisely matched to the material properties.
The frequency determines the penetration depth of the induced currents. High frequencies tend to heat the surface, whilst lower frequencies penetrate deeper into the material.
The geometry influences the field distribution and thus the heat generation. Even small changes can alter the heating behaviour and the quality of the solder joint.
The induction coil generates the electromagnetic field used in induction soldering. It determines how precisely and efficiently heat is introduced into the solder joint.
