Laminate and prepreg material targets high-speed digital designs by eliminating fiber weave skew through proprietary resin and reinforcement technologies. The material supports differential signaling at 224Gbps PAM4 and beyond, addressing timing mismatch caused by glass weave structures in traditional laminates. It delivers dielectric constant (Dk) of 2.80 and dissipation factor (Df) of 0.0007, stable across frequency up to 110GHz. Measured insertion loss is approximately 1.05dB/inch at 56GHz on 7-mil differential pairs with HVLP4 copper, with lower loss projected using HVLP5. The material supports standard FR-4 processing, including CO2 and UV laser drilling, with no fiber pull-out or residue. It provides peel strength greater than 5pli on HVLP4 copper and supports stacked microvia reliability through 500-cycle testing. Designed for applications including PCIe 7 and next-generation high-speed interconnects, the laminate enables consistent signal integrity without requiring panel rotation or routing compensation techniques.
