Abstract
Recent evaluations and early application trials have demonstrated that Flexiramics®, a European‑developed ceramic microfiber nonwoven reinforcement, can deliver measurable benefits in XY thermal spreading and RF/mmWave stability when integrated into advanced substrate and packaging materials. These results represent a new development in reinforcement architectures for high‑frequency and high‑thermal‑load electronics, offering an alternative to traditional woven glass fabrics.As devices move into the 28–110 GHz domain and thermal densities continue to rise, the limitations of glass‑reinforced dielectrics are becoming more pronounced. Woven glass introduces anisotropy, resin‑rich pockets, and local dielectric variation, all of which can affect signal uniformity and thermal performance. These constraints are increasingly visible in multilayer substrates, advanced packaging, and next‑generation RF systems.Flexiramics addresses these challenges through a continuous ceramic micro‑network that can be incorporated into existing polymer matrices and lamination processes.Recent test data and early customer evaluations indicate three key areas of impact:• XY thermal dissipation - application trials show that the ceramic network supports more efficient lateral heat spreading, helping reduce hotspot formation. This is designed to support improved thermal stability in high‑density architectures• RF/mmWave stability - initial RF measurements demonstrate stable dielectric behaviour across 30–110 GHz, with reduced sensitivity to local reinforcement effects. This is particularly relevant for communication, radar, sensing, and advanced packaging applications• Beyond glass - by eliminating woven‑fabric artifacts, Flexiramics provides a more uniform reinforcement environment. Early evaluations indicate more predictable electrical behaviour across the panel compared to glass‑based systemsBeyond technical performance, Flexiramics contributes to broader European strategic objectives. The platform is developed and manufactured within the EU, supporting regional supply‑chain resilience for advanced materials. Its scalable production approach enables both early‑stage prototyping and industrial‑scale deployment.The presentation will share new evaluation data, application examples, and insights from ongoing collaborations, illustrating how a new reinforcement architecture can help Europe advance toward more capable, efficient, and reliable electronic systems.
