1. Introduction of CuClad 217
Rogers CuClad 217 laminates are cross plied, woven fiberglass and precisely controlled PTFE composite laminates that offer low dielectric constant values of 2.17 or 2.20. CuClad 217 laminate's cross plied construction provides in-plane electrical and mechanical isotropy. CuClad 217 uses a low fiberglass/PTFE ratio to provide the lowest dielectric constant (Dk) and dissipation factor available in fiberglass reinforced PTFE based laminates. Together, these properties offer faster signal propagation and higher signal/noise ratios.
