The Imperfect Via: Modeling Challenges Impacting Simulation Accuracy May 25, 2025 - (0)
During DesignCon 2025, I had several side discussions about the findings presented in my DesignCon 2024 paper on dielectric anisotropy. A key concern raised was the discrepancy between measured results and simulations when converting the out-of-plane dielectric constant (Dkz) to in-plane Dkxy using my heuristic method. While Isola’s Tachyon 100G showed an average material anisotropy […]
