Introduction of RO4003C
Rogers RO4003C materials are proprietary woven glass reinforced hydrocarbon/ceramics that combine the electrical performance of PTFE/woven glass with the manufacturability of epoxy/glass. These laminates provide tight control over the dielectric constant (Dk) and exhibit low loss, utilizing standard epoxy/glass processing methods at a fraction of the cost of conventional microwave laminates. Unlike PTFE-based materials, RO4003C does not require special through-hole treatments or handling procedures.
RO4003C materials are non-brominated and are not rated UL 94 V-0.
Features of RO4003C
Dielectric Constant: DK 3.38 ± 0.05 at 10GHz
Dissipation Factor: 0.0027 at 10GHz
Thermal Conductivity: 0.71 W/m/°K
Thermal Coefficient of Dielectric Constant: +40 ppm/°C (ranging -50°C to 150°C)
CTE Matched to Copper: X-axis 11 ppm/°C, Y-axis 14 ppm/°C
Low Z-axis CTE: 46 ppm/°C
Tg: >280°C
Low Moisture Absorption: 0.06%
