- Stretchable Inks: All essentials for producing stretchable Printed Electronics
Steve Paschky | Managing Director Sales & Marketing at SARALON GmbH Among the emerging areas for Printed Electronics (PE), wearables and automotive industries are rapidly adopting this technology on a commercial scale. These sectors are heavily investing in PE due to its several advantages mainly: PE supports invisible electronics PE eliminates the complexities of bulky electronics integrations PE allows direct printing on lightweight substrates, leading to substantial weight reduction #InMoldElectronics #WearableElectronics #TextileElectronics #StretchableElectronics #MedicalElectronics Stretchable electronics: A significant driver of Printed Electronics industry The transformative impact of PE is not only due to enabling experimentation with various ink materials and functionalities, but also encouraging the use of div erse substrate materials. More specifically in the wearables and automotive sectors, electronics printing on stretchable substrates is highly desirable: Stretchable electronics easily flex to fit complex car interior geometries. They offer excellent conformity to the human body ideal for health monitoring wearables and medical patches Fully integrated PE on textiles offer comfort and movement flexibility in smart garments They adopt easily to 3D shapes or thermoformed in the IME process perfect for automotive electronics To support these needs, Saralon GmbH has developed all the essentials for producing stretchable Printed Electronics. Stretchable Saral Inks© include Silver, Carbon-based and non-conductive inks for different stretchable and bendable substrates. On ink targets textile materials by containing larger silver particles to reduce unwanted permeation; the other is designed for printing on paper and thus doesn’t require high-temperature curing. Stretchable Saral Inks© are formulated to adhere to various substrates such as TPU, PC, PET, textile, paper, and other elastic or bendable materials. An inclusive system of compatible stretchable inks Stretchable Saral Inks© can be printed on top of each other, allowing for integrated printing in diverse combinations and stretchable overlays for healthcare and sports wearables, smart textiles, stretchable heaters, 3D smart objects, and high resistance stretchable Printed Electronics: Saral StretchSilver 800: for TPU and other plastics such as PC for thermoforming and IME Saral StretchSilver 500: Solvent-based stretchable conducting ink for textiles and other rough substrates Saral StretchSilver H2O 600: for sustainable paper and other bendable applications Saral StretchCarbon 100 for low-conductive bendable electronics (e.g. heaters) Saral StrecthDielectric 100 for encapsulation and protection of conductive layers Stretchable EL ink set for stretchable electroluminescent on TPU (e.g. wearables, security or promotional textile applications) Full compatibility of Saral Inks© is guaranteed leading to significant time and cost reduction in RnD at PE developers' end. All Saral Inks© are suitable for all types of screen printing and other printing processes, e.g., flexographic printing, pad printing, dispense and gravure printing. Ink adjustments based on request is also possible to meet the specific demands of innovative projects. Next, let’s move on to a brief overview of each ink, their properties and target applications. Saral StretchSilver 800: Solvent-based stretchable conducting ink for direct printing on TPU and other plastic stretchable surfaces. When printed on TPU and dried at 120°C for 10 min, it shows a good initial sheet resistance of 30 mΩ/sq/25 μm and very good adhesion on the surface. Printed Saral StretchSilver 800 conductive ink on PC withstands high temperatures, pressure, and elongation during the thermoforming process. This simplifies the fabrication of highly customizable and conformal 3D electronics for HMI applications e.g., in automotive and white industries. As the demand for IME continues to grow, manufacturers are looking for innovative ways to create products that meet both functional and aesthetic requirements. Presenting stretchability and thermoformability properties, SaralStretch Silver 800 offers greater design flexibility, easier electronics integration in 3D shapes and complex geometries, and significant weight and cost reduction due to the elimination of bulky conventional wiring systems. Compatibility with our screen-printable conductive adhesive – Saral SilverGlue Alpha 600 – makes it easy to apply SMD components on TPU/PC substrates and create stretchable/thermoformable hybrid electronics. Figure 1- Saral StretchSilver 800 printed on TPU Saral StretchSilver 500: Solvent-based stretchable conducting ink specifically designed for textiles and other rough surfaces. When printed on knitted fabric of PET/EL blend and dried at 120°C for 10 min, the initial sheet resistance is 25 mΩ/sq/25 μm. Bigger silver particle size in this ink prevents its penetration into the porous surface, resulting in good conductivity preservation upon stretch and after tension release. Performance tests conducted by STFI (Renown independent textile research institution in Saxony) benchmarking Saral StretchSilver 500 against an alternative stretchable ink available in the market indicated its superior properties in terms of stretchable conductivity, controllable printing thus process reliability and reproducibility. This ink is the optimised solution for smart textiles in sports, therapeutical, protective garments and other innovative applications. Figure 2- Saral StretchSilver 500 printed on textile Saral StretchSilver H2O 600: Water based stretchable conducting ink developed to withstand creasing lines in paper electronics thus doesn’t require high-temperature curing. Direct printed on paper and dried at 120°C for 2 minutes in oven, the ink shows a good sheet resistance of 40 mΩ/sq/25 μm. This ink is the specialty solution to the growing demand for more sustainable non-solvent and paper-based print applications. Due to its low temperature curing and bendability characteristics (creasing lines), Saral StretchSilver H2O 600 is ideal for paper-based and disposable electronics – smart labels for track-trace and logistics monitoring, medical applications e.g. lab-on-a-chip for diagnostics, diabetes sensors, etc. Figure 3- Saral StretchSilver H2O 600 printed on paper Saral StretchCarbon 100: Solvent-based stretchable carbon ink suitable for direct printing on different substrates such as TPU or bendable plastics. Characterized with high sheet resistance of 100 Ω/sq/25 μm (printed on PET and dried at 120°C for 5 minutes in oven), this ink is a promising candidate for stretchable electronic devices including resistors, sensors, or heating elements. Examples of such applications are wearables for sweat (moisture) sensing, heating bandages, and smart sportswear. Figure 4- Saral StretchCarbon 100 printed on TPU Saral StrecthDielectric 100: Solvent based stretchable insulating ink for protecting stretchable conductive layers. Saral StrecthDielectric 100 is fully compatible with all Saral Inks© therefore smoothly printable on top of and in combination with any of our silver- or carbon-based stretchable inks on paper, plastic, or textiles. After printing a transparent encapsulating layer is achieved that offers additional protection e.g. for electronic wearables. Recommended drying temperature is 120°C for 5 minutes.

- Paste Noise Absorber Technology for High Frequency Devices (110-170 GHz) and Packages
UJIWARA REI | Panasonic Electronic Materials Business Division | fujiwara.rei@jp.panasonic.com High-frequency devices, such as those used in beyond 5G and 6G technologies, require precise and reliable signal transmission for optimal performance. High-frequency signals are more susceptible to noise interference, which can degrade the quality and integrity of the transmitted data. Noise mitigation is crucial to ensure that the intended signal is accurately received and interpreted. Traditionally, noise-absorbing materials have been used as an effective method of making noise. Noise absorbing materials are generally sheet or sponge type. However, these types are difficult to apply beyond5G/6G devices which become smaller and more complicated. We are speaking in Boston on 12-13 June 2024 at The Future of Electronics RESHAPED USA Register now and come to hear our talk To solve this problem, we propose a noise-absorbing paste.

- Bridging the Divide: Transitioning from Lab-scale to Industrial-scale Equipment in Printed Electronics Development
Authors: Daan de Kubber, Jurgen Westerhoff, Ben Robesin SPGPrints b.v., Raamstraat 1-3, 5831 AT, Boxmeer, the Netherlands Printed electronics have gained significant attention for their potential to revolutionize various industries through cost-effective and scalable manufacturing processes. However, a critical challenge within this domain lies in the transition from lab-scale and pilot equipment to industrial-scale production. We want to shed light on the implications of this transition, emphasizing its impact on cost reduction, repeatability, and time to market. The initial stages of printed electronics development predominantly occur on lab and pilot equipment, where researchers and innovators prototype new applications. As these applications progress towards commercialization, the shift to industrial-scale equipment becomes inevitable. Rotary screen printing emerges as a prominent technique, providing high-throughput capabilities essential for large-scale production. We are Speaking at the Free-To-Attend On-Line Innovations Festival on 25 April 2024. Register to hear our talk, and meet us during the virtual networking. We have looked critically at this transition. Investments in Industrial-scale equipment, though substantial, ultimately leads to significant cost reductions in large-scale production. This is essential if manufacturers want to achieve sustainable, cost-effective printed electronics. Moreover, the transition to industrial-scale equipment like Rotary Screen Printing enhances repeatability and quality control. Lab-scale equipment often lacks the precision, required consistency and capacity for mass production. In contrast, industrial-scale tools offer robust control mechanisms, ensuring consistent output across large volumes. This shift results in higher product quality consistency, reducing defects and improving overall yield rates. A great example of a printed electronics application that is moving into high-volume industrialized scale are the printed e-paper displays by our partner Ynvisible. Their products are used on smart labels, IoT devices, retail signage and many more markets. Ynvisible even shares their know-how in scaling up printed electronics with other companies in the flexible solar and printable battery space. Printed ultra-low-power display for use in retail If we take the e-paper example and run it through our cost-per-print calculator you see that for a yearly production of 3.5 million e-paper displays the Rotary Screen Printing solution starts to become more profitable within 3 years of production. This shows that you need relatively high volumes to justify the investment in a full SPGPrints Rotary screen printing line, but it will pay off and will ensure steady profitable business in the long run. Of course SPGPrints also offers screen printing units that can be integrated into an existing or custom built line, changing the business case significantly. Next to owning the equipment SPGPrints (and our network of print service providers) offers Production-as-a-Service including application development consultancy. This is a calculation showing the cost per printed unit comparison between typical flat-bed screen printing and a full SPGPrints rotary screen printing line. It is imperative to acknowledge that transitioning equipment mid-development cycle extends the time to market. This delay arises from the need to recalibrate processes, optimize formulations, and adapt to the unique characteristics of industrial-scale equipment. This delay represents a critical trade-off, where time saved in large-scale production is weighed against the extended development phase. In conclusion, the transition from lab-scale and pilot equipment to industrial-scale production, like Rotary Screen Printing, plays a pivotal role in advancing printed electronics. While the cost reductions and enhanced repeatability are substantial benefits, it is important to recognize the inherent time-to-market trade-off associated with this transition. In this paper we will show some examples of how choosing for industrial-scale equipment at an early stage in development, saves time and money in the long run. Additionally, we will provide a calculation method to evaluate the most suitable production equipment for a specific application.

- Flexible Microelectronic Devices produced with Sputtered Coatings and Laser Patterning
Authors: Mike Simmons, Matthew Kleyn, Joseph Vlach, Liz Josephson; Intellivation LLC ljosephson@intellivation.com | Intellivation The demand for high-performance devices with enhanced functionalities continues to grow. Materials, such as graphene and MoS2, exhibit unique electrical and mechanical properties making them ideal for flexible electronic applications. To meet the rising demand and requirements for flexible 2D microelectronics devices manufactured using Roll to Roll technology, we use innovative manufacturing techniques including vacuum coatings in combination with laser technology. Laser patterning of sputtered coatings provides the ability to achieve high-volume production with precision, functionality and efficiency for a wide range of flexible applications. Sputter deposition is a widely used technique for depositing thin films onto substrates. For flexible 2D microelectronics, sputtered coatings serve as the foundation for building functional devices. Sputtering involves bombarding a target material with ions to eject atoms or molecules, which then deposit onto a substrate to form a thin film. This process allows for precise control over the thickness and composition of the deposited film, making it a preferred method for creating uniform and reproducible coatings. Sputtered layers were deposited using Intellivation’s R2R Lab system. Sputtering provides an excellent method for depositing coatings uniformly over large areas, while laser patterning can create discrete devices, circuits, and other types of discontinuous features required for manufacturing. Using these two techniques in combination provides unique capabilities, particular during product development. Photolithography requires multiple steps and is time consuming, it also requires geometric commitment of features at early stage of design. Laser patterning offers a direct and efficient way to create and define patterns on sputtered coatings including changes in geometry while providing consistent feature size and edge quality. Laser patterning uses a laser beam to selectively remove or modify specific areas of deposited films enabling the generation of intricate patterns with submicron-level precision. Control and precision of the laser is critical and the non-contact nature of laser patterning reduces the risk of contamination and damage to the underlying substrate, ideal for delicate 2D materials. This technique provides the ability to develop and then validate a design and process in small volumes and then easily transfer to large area roll-to-roll production without changes to the laser processing equipment. Deposition of the conductive material onto the substrate was done with Intellivation’s R2R thin film vacuum deposition Lab coater , it is then laser patterned or the laser is used to isolate regions to crystallize them for interfacing with subsequent layers. Once the substrate, layer stacks and laser variables are optimized, the next phase is to scale these devices to large area R2R processing. The combination of laser patterning and sputtered coatings has unlocked new possibilities in the high-volume production of flexible 2D microelectronics. This innovative approach addresses the demand for devices with enhanced performance, precision, and scalability. A roll-to-roll approach offers several significant advantages in terms of efficiency, cost and adaptability.
- Extending the pot life of silicones to several months: LEDs, 3D printing and beyond
How to extend the pot life of silicone to several months without changing its material properties? Ulrich Trog [Ulrich.Trog@joanneum.at | JOANNEUM RESEARCH] explains in this article how this is possible JOANNEUM RESEARCH offers the formulation of the appropriate compound based on feasibility studies of the silicones used by its customers. Licences for the Supresil™ technology are available. Platinum (Pt)-cured silicones are gaining in popularity, emphasising addition curing over traditional peroxide methods. This process ensures purity and efficacy, resulting in products with increased strength and superior aesthetics. The rise of Pt-curing marks a significant shift in silicone manufacturing techniques, promising unmatched quality and durability in a variety of applications. When crosslinking is initiated, the curing process starts almost immediately and the resulting silicone typically has a pot life limited to a maximum of a few hours at room temperature. This places significant practical and technological limitations on its use: short processing time manufacturing waste difficult reproducibility inflexible manufacturing process Our patented formulation greatly increases pot life via reversible inhibition of the crosslinking via hydrosilylation. After deposition, the inhibitors evaporate easily. Normal crosslinking occurs at mild temperatures, even below 80 °C, leading to a fast and complete curing.

Learn more https://www.techblick.com/electronicsreshapedusa Benefits reduces production costs: the pot life of silicone mixtures can be extended to several months and beyond enables (3D) printing: shelf stable, 1-component silicone inks can be formulated for use with a variety of printing processes like dispensing, screen-printing, aerosoljet-printing, inkjet printing and others no change in material properties: through the complete and trace-free removal of the inhibitor during the curing process there is no change in the material or its properties applicable to liquid Silicone rubber (LSR) and high consistency rubber (HCR) suitable for all Pt-cure resins: no curing at processing temperature and normal curing at curing temperature, orthogonal with other inhibitors environmental: reduction in waste generation in production process Application examples LED production: Supresil™ resins reduce the processing efforts and increase the yield of colour conversion materials without changing their optical properties. The Supresil™ inhibited silicones can be mixed with colour conversion phosphors in large batches, increasing the accuracy and consistency of the colour conversion composites through improved wetting and distribution of the dispensed material and a better dispersion of the phosphors. 3D printing: Standard LSR formulations are optimised for extrusion and injection moulding machines and are not suitable for 3D printing. By adjusting the rheological behaviour and extending the pot life using JOANNEUM RESEARCH‘s proprietary reversible curing inhibition, 3D printing is now possible. All material properties of the silicones are preserved (through complete and trace-free removal of the inhibitor): physical: shrinkage, Shore hardness, storage modulus optical: UV/VIS transmission, no „yellowing“, refractive index biocompatibility: relevant for medical grade resins / formulations unaltered production: viscosity, reproducibility Fig. 1: Comparison of curing dynamics of standard silicone resins with SupresilTM inhibited resins We are Exhibiting in Berlin!
