Innovative semi-finished goods for the electronics industry
In the electronics and consumer goods sectors, consistent quality, dimensional accuracy, and flawless surfaces are essential for the function and design of modern products. With the isobaric double-belt presses from HELD Technologie, multilayer laminates, films, and composite materials can be produced continuously and with high precision—from PCB laminates and display structures to decorative high-gloss surfaces.
Whether smartphones, laptops, tablets, wearables, speakers, power control units (PCUs), or components for 5G infrastructure: modern electronic products require materials that are lightweight, high-strength, thermally stable, and suitable for high-frequency applications.
Precisely controlled temperature and pressure profiles create materials with optimal adhesion and surface quality, forming the basis for durable electronic components and sophisticated design products. HELD Technologie thus connects technical precision with aesthetic perfection in an increasingly material-driven industry.
Electro-laminates – the core of modern electronics
Electro-laminates form the foundation of every printed circuit board (PCB). They provide stability, insulation, and precise electrical properties. With HELD Technologie’s double-belt presses, copper-clad laminates (FCCL) and high-quality PCB materials can be produced reproducibly and efficiently. These materials are used in smartphones, tablets, laptops, wearables, and power control units (PCUs).
For applications in the 5G and high-frequency sector, our systems enable the production of laminates with low dielectric loss (Low Dk/Df), making them ideal for antenna modules and RF boards. In addition, electrical insulation films ensure the safe separation of sensitive circuits, while integrated Thermal Interface Materials (TIMs) ensure optimal heat dissipation.

For 5G: High-frequency laminates with low dielectric loss (Low Dk/Df) for antenna modules and RF boards.
Electrical insulation: Electro-laminates and specialised electrical insulation films ensure the safe separation of circuits and serve as insulating materials for PCBs and power electronics.
Thermal Interface Materials (TIMs): Electro-laminates can be combined with thermally conductive layers and form the basis for highly efficient heat dissipation in chips, GPUs preventing overheating and maximising performance.
Production of HPL/CPL decor surfaces
Applications: Premium surfaces for housings, keyboards, covers, and smart speakers.
For 5G: Decorative surfaces with optimised signal permeability.
Speaker membranes: Thin decorative laminates can also be used in acoustic design.
Organosheets (glass- or carbon-fiber reinforced thermoplastics) combine high strength with low weight and open up new possibilities in modern product design. With HELD’s isobaric double-belt presses, these materials can be produced continuously and with high precision. They are used in structural components of smartphones and laptops, where they enable stable, lightweight housings while also serving as mechanically robust carrier structures for 5G antenna modules. In addition, fiber-reinforced thermoplastics are ideal for high-quality speaker membranes, as they offer excellent vibration characteristics together with precise dimensional stability. As materials for structural and thermal-interface components, these composite semi-finished products provide both mechanical stability and thermal conductivity—an ideal solution for compact, high-performance devices such as smartphones, tablets, or gaming laptops.

Prepregs – high-performance composites for electronics and 5G technology
Prepregs are the backbone of modern electronics manufacturing. With HELD Technologie’s isobaric double-belt presses, endless prepregs with thermoset or thermoplastic resin systems are produced with precision, uniformity, and energy efficiency. These composite materials form the foundation for display covers, housing reinforcements, and PCB structures - everywhere stability, insulation, and heat dissipation are essential.
For the 5G generation, HELD prepregs serve as intermediate layers in multilayer PCBs, enabling high-frequency capable circuit boards with optimal electrical properties.
By combining epoxy or polyimide resins, they also play a crucial role in the electrical insulation of sensitive components in power electronics. In applications with high power density—such as AI processors, gaming hardware, data centers, or power semiconductor: prepregs with thermally conductive fillers ensure highly efficient thermal management.
They prevent overheating, secure maximum performance, and extend the lifetime of electronic systems an increasingly critical factor in consumer electronics as well.
With state-of-the-art press technology, HELD delivers precisely manufactured prepregs that combine quality, reliability, and innovation in electronic production for the long term..
Technical films and thin laminates form the basis of modern electronics and display technologies. With HELD Technologie’s isobaric double-belt presses, polyimide, polycarbonate, and PVC films can be produced with the highest precision and consistent quality; ideal for flexible displays, protective layers, and insulation films in demanding applications.
For 5G technology, polyimide films offer optimal properties as flexible substrates for RF circuits and antenna modules. Their combination of high dielectric strength, temperature resistance, and chemical stability makes them indispensable for electrical insulation in modern PCBs and electronic assemblies.
In addition, TIM composite films with thermally conductive layers enable efficient heat dissipation in high-performance chips, GPUs, and compact end devices.
In this way, HELD films make a decisive contribution to increasing the performance, reliability, and lifespan of electronic systems.
