Metals for the electronics & EMS industry
Solder, alloys and semi-finished products for reliable connectionsThe demands placed on materials in electronics production are high: precision, purity, processability - and as sustainable as possible.
We supply EMS service providers and electronics companies with tin- and lead-based materials that have proven themselves worldwide - in series production as well as in development.
Typical applications for electronic solders
Our materials are used in almost all areas of modern electronics production. These primarily include the SMT and THT assembly of printed circuit boards, the assembly of electronic components and cable assembly for devices and systems of all kinds.
Another key area of application is communication technology - for example in RF assemblies, signal processing units or network systems, where high-purity materials and reliable solders are crucial for signal quality.
The production of the bare circuit board (printed circuit board) - i.e. the carrier made of glass fiber, epoxy resin or similar with copper tracks and drill holes. It forms the "platform" for the subsequent electronics.
Mounting electronic components on the finished printed circuit board by soldering (SMT/THT)
SMT (Surface-Mount Technology):
Components are soldered directly onto the surface of the PCB. This process is now standard for complex electronic assemblies.
THT (Through-Hole Technology):
Components are inserted through drilled holes and soldered on the back - often for robust or high-performance components.
Reliable soldered connections are crucial for both processes. This is where our high-purity tin and lead materials and customized solder alloys come into play - for stable, reliable production.
Refers to the individual production and preparation of cables for installation in electronic or electrical systems. Cables are cut to size, stripped and fitted with connectors, ferrules or contacts - precisely tailored to the subsequent application. Pre-assembled cables are used in almost all sectors, such as industrial electronics, mechanical engineering and automotive engineering. High-quality materials and clean soldered or crimped connections are essential for reliable electrical connections.
Places the highest demands on materials, precision and long-term reliability. In medical devices such as imaging systems, patient monitors or implant components, electronic connections must not only function precisely, but also be biocompatible, corrosion-resistant and absolutely fail-safe. This is why high-purity metals and lead-free solders that meet strict standards and regulatory requirements are preferred.
Includes electronic signal processing and transmission in applications such as network components, mobile radio technology, satellite communication or signal amplifier systems. In these areas, low contact resistances, precise conductor structures and high-quality soldered connections are crucial for stable, low-loss signal transmission. The materials used must function reliably at high frequencies and in complex system environments.
Describes the development and production of extremely compact electronic circuits, such as those used in sensors, wearables, mobile devices or automated control systems. The processing of the finest structures, miniature parts and temperature-sensitive components is required here - the demands are correspondingly high.
Used wherever high electrical currents or voltages are controlled - for example in drive controls, inverters, battery management systems or charging infrastructure. The resulting thermal and mechanical stresses require high-strength, temperature-resistant alloys that ensure a stable long-term connection between components and circuit boards.
Combines precision mechanics with electronic evaluation - for example in laboratory equipment, industrial test systems or digital measuring tools. Here, electrical connections must be precisely defined, reproducible and interference-free in order not to impair the signal quality. This is why high-quality materials, contamination-free solders and precise processing methods are used. For pneumatic or hydraulic measuring systems such as pressure gauges, we manufacture insert solders from the groups SnCu, SnAg, SnAgCu, SnPb, SnIn, SnBiCu, BiSnAg and PbSnAg.
One of the most demanding industries when it comes to the reliability of electronic components. In airplanes, satellites and control systems, materials must function permanently under extreme temperature, pressure and vibration conditions. Only certified alloys and high-purity metals that are both mechanically resilient and stable over the long term are used here. Lead-free solders with defined melting behavior are particularly in demand, as they enable interference-free signal and energy transmission even under changing environmental conditions.
The right format for your process
In electronics production, not only the alloy, but also the format of the material is crucial for a stable and efficient production process. Whether solder bars for wave soldering systems, wires for manual and selective soldering, granulate for dosing processes or anodes for galvanic coatings - we supply you with materials that are precisely tailored to your systems, quantities and process requirements.

Technological change in EMS production
Electronics production is on the verge of a radical change: lead-free solders are increasingly replacing leaded variants - driven by legal requirements and rising environmental standards.
Challenge: Reliability despite higher thermal and mechanical loads
Development: New soft solder alloys for demanding series processes
Focus: Process reliability, conformity to standards & long-term performance
We supply EMS-compatible alloys with documented quality - developed for the requirements of today and tomorrow.
2006
RoHS I (Restriction of Hazardous Substances Directive) requires the transition from leaded to lead-free solders
2011
RoHS II is the revised version of the EU directive on the restriction of hazardous substances in electrical and electronic equipment with even stricter obligations
2025
The remaining special regulations for the use of certain hazardous substances (e.g. lead in solders) are gradually being phased out.
New requirements for lead-free solders
Legal requirements such as RoHS or REACH are forcing the reduction of substances that are harmful to health and the environment - this applies in particular to solders containing lead. This results in complex requirement profiles for modern soft solder alloys:
Low melting range (< 200 °C)
Protection of temperature-sensitive components during reflow & wave soldering
Constant soldering parameters
Wetting, penetration & flow behavior should remain comparable to leaded solders
Suitable for new processes
z. e.g. laser soldering, selective soldering, 3D printing processes
100% CMRT-compliant
Origin from conflict-free sources - documented & traceable
Take the leaching effect into account
Reduce material losses on blanks, tools and systems
GreenTin+
Pure tin made from 100% recycled material
GreenTin+ is an ecologically sourced material of the highest quality that can be purchased as pure tin in the form of bars, rods, wires and anodes.
Alternatively, it is also available as the main alloy component in all relevant lead-free electronic solders.
