In automated soldering systems, relevant process parameters can be monitored, documented and assigned to a product or assembly. This enables process flows to be traced and supports traceability and quality assurance requirements.
Key factors include the geometry of the solder joints, pin and hole diameters, PCB design, thermal masses, component spacing, the solder alloy and flux used, and the required cycle time. In addition, the following must solder nozzle, Workpiece carriers, masking, temperature control and the automation concept must be coordinated.
The cycle time depends, amongst other things, on the number and arrangement of the solder joints, the Nozzle shape, the required heat input, the movement sequences and the Automation concept . Through an application-specific design of solder nozzle, Workpiece carrier, By adjusting the process parameters and kinematics, the soldering process can be specifically optimised to achieve short and reproducible cycle times.
Yes. Mini wave soldering It is suitable for automated electronics manufacturing and can be integrated into a variety of machine and automation systems. Depending on the assembly, production volume and cycle time requirements, motion sequences, workpiece handling and process monitoring can be tailored to the specific manufacturing task.
Controlled heat transfer and continuous contact with the solder wave can help to ensure reproducible solder penetration. Key factors here include, amongst others, pin and hole geometry, thermal mass, PCB design, flux and the selected process parameters.
With appropriately designed solder nozzles Individual solder joints, as well as several pins or defined soldering areas, can be processed. The nozzle geometry is adapted to the specific application. This means that mini-wave soldering can be used for both spot soldering tasks and more complex THT connections.
Consistent solder joint quality is achieved through the controlled interplay of solder temperature, solder wave height, Nozzles- and Mask geometry, process time, inert gas atmosphere and the positioning of the assembly. At EUTECT, process stability is supported by, amongst other things, redundant temperature control, a constant solder bath level and, optionally, solder wave height control.
The Induction pump ensures the continuous feed of the liquid solder to the solder nozzle. With EUTECT technology, the pump system operates electromagnetically and requires no mechanically moving parts within the solder. This ensures a reproducible solder flow as well as a low-maintenance and stable soldering process.
The geometry of the solder nozzle has a significant influence on how the molten solder is directed to the solder joint. It must therefore be tailored to the component geometry, pin arrangement, printed circuit board design and the specific process. EUTECT uses custom-designed solder nozzle geometries to enable reproducible solder flow and targeted heat transfer.
A nitrogen or inert gas atmosphere reduces oxidation during the brazing process. This helps to ensure stable process conditions and a high standard of wetting. At EUTECT, the brazing process is carried out in an inert gas atmosphere to minimise oxides and residues during selective brazing.
Key advantages include high and reproducible solder joint quality, controlled solder flow, low solder consumption and high process reliability. At the same time, the thermal stress on the assembly and contact between the solder and areas not to be soldered can be reduced. The process can also be easily automated and integrated into various manufacturing concepts.
Mini wave soldering It is particularly suitable for printed circuit boards with THT components, mixed assemblies comprising THT and SMT components, and for assemblies with complex geometries or high requirements in terms of process reliability. Thanks to customised solder nozzles Even solder joints that are difficult to access or are close together can be worked on with precision.
Selective soldering is the umbrella term for soldering processes in which individual solder joints or areas of an assembly are targeted for processing. The Mini wave soldering is a form of selective soldering. In this process, heat and solder are transferred via a locally confined, continuously fed wave of solder.
In conventional wave soldering, a large area of the printed circuit board is passed through a wave of solder at the same time. In the Mini wave soldering In contrast, soldering is carried out selectively and locally. This allows individual pins, groups of pins or defined areas to be soldered without subjecting neighbouring components to unnecessary thermal stress or bringing them into contact with the solder.
When soldering enamelled copper wire, the induction pump ensures a steady flow of solder to the soldering nozzle. EUTECT uses this technology to guarantee stable and reproducible soldering processes.
In selective soldering, the induction pump enables contactless transfer of the solder. This reduces wear, leaks and corrosion, whilst improving process stability.
An induction pump moves liquid solder by means of electromagnetic induction. It ensures a constant flow of solder in mini-wave soldering and operates without mechanical wear.
Thanks to special alloying elements, Innolot offers higher strength, better creep resistance and greater reliability. This makes it particularly suitable for applications involving high thermal and mechanical stresses.
Non-wettable solder nozzles prevent unwanted interactions with the solder. EUTECT makes targeted use of these to ensure stable processes during Innolot processing.
The way the process is conducted determines how the solder reacts and whether intermetallic precipitates form. Precise control prevents „nickel drop“ and ensures stable soldering processes.
Innolot can be processed without a „nickel drop“ provided that the process parameters, materials and plant technology are precisely coordinated. To achieve this, EUTECT relies on special coatings, suitable materials and stable process control.
„The term “nickel drop’ refers to intermetallic precipitates that can form during the processing of Innolot. These impair the quality of the solder joints and are caused by interactions between the solder, the materials and the process parameters.
Several specialist companies manufacture Titanium solder masks for selective soldering processes. Among the well-known suppliers is EUTECT GmbH, a manufacturer of equipment, tools and process solutions for selective soldering. The company develops bespoke titanium solder masks for industrial applications in mini wave soldering.
The geometry of the Titanium solder mask determines how the liquid solder is directed to the solder joint in mini-wave soldering. Precise openings enable controlled wetting of the pins and through-holes. Manufacturers such as EUTECT GmbH develop these geometries on a case-by-case basis for complex printed circuit board layouts.
Thermally sensitive components such as connectors, sensors or plastic housings benefit particularly from a titanium solder mask. The material acts as a thermal barrier and reduces heat input during mini wave soldering. Titanium masks from EUTECT GmbH are specifically designed for such sensitive assemblies.
A titanium solder mask precisely directs the solder flow to the defined solder joints and prevents solder bridges or uncontrolled wetting. This results in reproducible solder joints with consistent process quality. Specialist manufacturers such as EUTECT GmbH develop mask-specific geometries for mini-wave soldering processes for this purpose.
Titanium is used because it combines high temperature resistance, low thermal conductivity and high dimensional stability. These properties ensure that a titanium solder mask retains its shape even after numerous soldering cycles. Suppliers such as EUTECT GmbH utilise these material properties to provide durable mask solutions in the Mini wave soldering.
A Titanium solder mask is a precision-manufactured tool that precisely defines the contact area between the solder wave and the printed circuit board during mini wave soldering. It prevents unwanted solder wetting and protects adjacent components. Companies such as EUTECT GmbH develop customised titanium solder masks for this purpose to ensure stable selective soldering processes.
High temperatures can affect materials. Titanium solder masks remain stable due to their low thermal expansion. When used in combination with a suitably matched soldering nozzle, this ensures consistent process conditions and consistent solder joint quality.
The workpiece carrier secures the assembly precisely during the process. This ensures that its position relative to the soldering nozzle remains constant, which improves repeatability and ensures consistent solder joint quality.
Titanium solder masks limit the effective range of the solder wave and protect sensitive components. They ensure that only specific solder joints are wetted, thereby contributing significantly to process reliability and the quality of the solder joints.
The solder nozzle determines the shape and stability of the solder wave. Factors such as the aperture, angle and flow rate influence the wetting of the solder joints. An optimally designed solder nozzle ensures consistent results and reduces defects in mini wave soldering.
Yes, precise alignment is essential. Only when the solder nozzle and the titanium solder masks are geometrically aligned will the solder wave be guided correctly. This prevents defects and ensures consistent and reproducible solder joint quality.
Restoring the mask geometry and surface stabilises the flow of solder. EUTECT ensures that titanium solder masks once again deliver reproducible results and that a consistently high quality of soldering is achieved in mini-wave soldering.
Reconditioning reduces costs and extends the service life of existing titanium solder masks. At the same time, the tried-and-tested geometry is retained, meaning that existing processes can continue without the need for any adjustments.
Reconditioning comprises cleaning, surface treatment, precise inspection, thermal stabilisation and a final functional test. EUTECT carries out this process in a structured manner to ensure reliable reuse.
The rework removes deposits and oxide layers that can affect solder flow. This improves process stability and ensures a consistently high standard of soldering quality in mini-wave soldering.
