Designed for extreme thermal stability, featuring advanced glass transition structures, high-frequency SMT packaging, and superior heat extraction technologies.
In the modern electronics landscape, thermal management has become the primary bottleneck for system reliability. As Swedish industries transition toward smart manufacturing, electrification, and high-frequency communication infrastructure, the demand for High-TG (Glass Transition Temperature) printed circuit boards has surged exponentially. The Glass Transition Temperature represents the temperature threshold at which the base polymer resin transitions from a rigid, glassy state to a flexible, rubbery state. Standard PCBs typically function with a Tg of 130°C to 140°C. However, for operations exposed to sustained elevated temperatures, standard boards fail due to delamination, warpage, and structural breakdowns of copper vias. High-TG PCBs (featuring Tg >170°C) prevent these issues, ensuring long-term mechanical stability and signal integrity under extreme thermal profiles.
Sweden has established itself as a global leader in high-tech manufacturing, telecommunications development, green energy transition, and advanced automotive engineering. Companies in cities such as Stockholm, Gothenburg, Linköping, and Malmö are pushing the boundaries of electronics design. For instance, automotive pioneers driving vehicle electrification require onboard charging systems (OBC) and battery management systems (BMS) that can withstand severe thermal expansion stresses. In addition, telecommunication providers rolling out massive 5G/6G infrastructures across Scandinavia require base station RF modules and high-speed processors that maintain tight impedance control even under sustained heat loads in remote locations.
Furthermore, Sweden’s aggressive carbon-neutral targets have spurred significant growth in renewable energy systems, high-voltage smart grids, and high-power EV charging infrastructure. These systems handle currents that raise the ambient and internal operating temperatures of electronic control assemblies. Utilizing High-TG PCBs prevents Z-axis coefficient of thermal expansion (CTE) mismatches, which can cause micro-via cracking and solder joint fatigue during rapid temperature cycling. Cynovex’s high-TG PCB fabrication and SMT capabilities are engineered specifically to satisfy these strict Swedish industrial standards (such as SS-EN ISO 9001 and high environmental compliance mandates).
When operating high-frequency systems such as DDR4/DDR5 memory modules and advanced motherboards, the dielectric loss and signal attenuation are directly impacted by the base laminate material's thermal properties. As the temperature of a standard board approaches its Glass Transition Temperature, its relative permittivity (Dk) and dissipation factor (Df) shift rapidly. This instability introduces timing jitter, crosstalk, and impedance mismatches, which degrade system stability.
Cynovex integrates high-TG substrates with low coefficient of thermal expansion (CTE) parameters to ensure that high-frequency lines maintain strict 50-ohm single-ended and 100-ohm differential impedance tolerances. This is particularly crucial for systems deploying high-speed DDR4 desktop and laptop modules, where routing density is tight and operating temperatures can exceed 85°C. By implementing advanced multilayer stack-ups using high-TG FR4 (such as Shengyi S1000-2M or ITEQ IT-180A), we ensure our board designs prevent thermal delamination, providing a reliable substrate for high-power processors, edge computing, and industrial control environments.

A high-performance PCB design is only as effective as its surrounding thermal management components. In server, HPC (High-Performance Computing), and heavy industrial automation applications, dissipation paths must be continuously active. Cynovex’s product portfolio addresses this reality by integrating advanced heatsink designs—such as copper bottom air coolers and integrated liquid cooling blocks—directly with high-TG SMT motherboard assemblies.
For example, in server blades where processors dissipate up to 300W of heat, relying solely on standard cooling setups will lead to thermal throttling and localized PCB hot spots. Hot spots induce localized Z-axis expansion on the board, which can rupture internal micro-vias. Implementing a system that pairs high-TG multilayer PCBs with custom cooper-bottom server coolers (such as our SP5 2U or LGA4926 solutions) provides a comprehensive thermal management approach. The high-TG PCB resists localized thermal stresses, while the copper heatsink absorbs and moves heat away from critical components, maintaining optimal semiconductor temperatures.

Exporting advanced electronics and PCB assemblies to Sweden requires compliance with European Union directives and national regulations. Cynovex ensures all products shipped to Sweden meet RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations, preventing lead, mercury, cadmium, and other hazardous materials from entering your supply chain.
Additionally, we assist Swedish importers with customs clearance, classification under the Integrated Tariff of the European Union (TARIC), and compliance with the Waste Electrical and Electronic Equipment (WEEE) directive. Our logistics partners provide direct shipping routes from our primary hubs to Stockholm Arlanda (ARN), Gothenburg Landvetter (GOT), and key regional warehouses, offering options for air freight, sea freight, and express courier (DHL/UPS/FedEx) delivery. We provide DDP (Delivered Duty Paid) and CIF (Cost, Insurance, and Freight) terms to simplify the import process, ensuring your goods arrive on time and fully compliant with Swedish regulations.
As electronic systems grow more compact and power densities increase, traditional FR4 materials are reaching their limits. The industry is moving toward high-TG substrates with low loss tangents (Df < 0.005) and low dielectric constants (Dk < 3.5). Cynovex is tracking this trend by evaluating next-generation PTFE and polyphenylene ether (PPE) resin blends. These materials deliver stable electrical performance at frequencies up to 77 GHz, making them suitable for advanced automotive radar, high-speed backplanes, and 6G telecom hardware.
We are also optimizing our lead-free reflow profiles. Because lead-free solders require higher peak temperatures (typically 245°C–260°C), the base laminate is subjected to high thermal shock. Our R&D team is refining multi-layer stack-up microvia designs and buried/blind via structures to ensure they can withstand consecutive reflow cycles without delamination or barrel cracking.
