Cable Assemblies - capabilities for our customized solutions
Creating high-quality cable assemblies requires extensive knowledge of connectors, cables and processing technologies. The ability to meet the technical demands of the customer applications in terms of the final cable assembly and to use the most cost-effective manufacturing methodology, based on a choice of various manufacturing locations in Eastern Europe and Asia, makes ASSMANN WSW the partner that gives its customers a significant advantage. ASSMANN WSW supplies a wide range of standard cable assemblies from stock and specializes in the production of customized cable assemblies based on common industry standards. In addition to using our own connectors in industrial cable assemblies, competitive products from wellknown manufacturers can also be used on customer request to ensure our cable assemblies can be used worldwide by our customers, our manufacturing facilities in Asia and Slovakia are UL certified. The array of cable assemblies required and demanded is just as great as the variety of customers from the individual industry sectors. The requirements placed on cable assemblies have grown in line with the ever-increasing quality demands of the industry. As a global manufacturer and supplier, we execute your individual projects from single wire assembly to complex cable harnesses.
Capabilities for Medical
In medical technology, every connection and stable temperatures matters. ASSMANN WSW offers a broad range of connector, thermal management and cable assembly solutions, designed to meet the high demands of sensitive and long-lasting applications. From flexible FFC connectors and cables, modular interfaces our customized solutions ensure stable signal transmission, mechanical robustness, and long service life even under challenging conditions. Every step follows a consistent quality process. Specialized materials (FDA), flame retardancy, and chemical resistance enable safe use of our cable assemblies even in sterile and safety-critical environments. Through customer-specific modifications such as contacts and their plating, sterilization-resistant materials, and enhanced contact reliability, we enable seamless integration of our connectors into medical devices. Certified quality according to international standards (e.g., ISO, UL, RoHS) forms the foundation for the safety and reliability of our products – a decisive factor for everyday medical use. From prototype to series production, our medical-grade connector solutions combine precise manufacturing with strict quality control – supporting the next generation of reliable and high-performance medical devices.
Custom-made coaxial cable
Technically evaluated. Implemented on a project-by-project basis. Not every connector combination is compatible with every cable type. Several technical parameters must be taken into account to ensure optimal signal transmission. Key Factors - Characteristic impedance (50 or 75 ohms) - Outer diameter and dielectric - Connection type: solder or crimp - Shielding configuration (important for shield attenuation) - Frequency range of the application - Mechanical requirements and operating environment We test every combination for technical feasibility and optimal performance to ensure a reliable solution for your project. Custom-made solutions Instead of standardized products, ASSMANN WSW manufactures coaxial cables exclusively according to individual customer requirements. Our services include: - custom cable lengths - custom connector combinations - project-specific testing procedures - prototype and series production This ensures you receive a connection solution precisely tailored to your application.
EMI/EMC Frames for shielding – the Electro Magnetic Compatibility
The EMC shielding EM shielding's are used to protect against electromagnetic emissions, even directly on the PCB, to ensure reliable operation. A suitable shielding design can ensure the reliable operation of RFID applications. For more complex circuit designs and applications, the shielding frame can also be constructed in several sections, with different cells, to ensure that the individual components are shielded directly on the PCB. The shielding not only protects against “incoming radiation,” but also prevents radiation from being emitted. An appropriate shielding design is therefore important to ensure the long-term reliability of the applications. The EMI Design EM shielding's for electronic housings, shielding frames for printed circuit boards, or even EM frames for testing rooms can feature different designs. One-piece frames for simpler applications, which are soldered directly onto the PCB, are used just as much as multi-piece variants made up of a frame and cover. With multi-piece variants, it is important to ensure that the connection between the frame and cover is as even and as large as possible. Only the best possible connection in the right design will achieve a correspondingly good shielding effect. The material used for the shielding is also an important factor that must be taken into account for the shielding effect, as different materials have different shielding effects. Only by combining the right material with the right design a suitable shielding effect will be achieved.
Skiving Heatsinks – Redefining Efficient Heat Dissipation: High-Performance Aluminum & Copper Heatsinks for Your Thermal Challenges
Skiving Heatsinks – Redefining Efficient Heat Dissipation: High-Performance Aluminum & Copper Heatsinks for Your Thermal Challenges When maximum cooling performance meets precision – skiving heatsinks are the best solution for powerful heat dissipation in the smallest possible space. This advanced technology for passive heat dissipation in demanding applications offers you high-precision, custom-manufactured skiving heatsinks. Skiving heat sinks impress with excellent thermal properties, high surface quality, and maximum customization – ideal for use in electronics, power electronics, LED technology, and industrial control systems. What is a Skiving Heatsink? In the skiving process, a fin structure is cut from a solid block of metal – usually aluminum or copper – by means of a precision machining process (skiving). The fins remain firmly attached to the base plate, ensuring outstanding heat transfer – completely free of air gaps as found in pressed-fin heatsinks, and without adhesives or solder joints. Skiving heatsinks can achieve fin ratios that are not possible with the extrusion process.
