Introducing our newly shipped PCB built on the RO4003C substrates. A high-performance laminate that combines the electrical properties of PTFE/woven glass with the manufacturability of epoxy/glass. The proprietary woven glass reinforced hydrocarbon/ceramic materials of RO4003C offer exceptional electrical performance and cost-effective circuit fabrication.
RO4003C laminates are available in various configurations utilizing 1080 and 1674 glass fabric styles, all meeting the same stringent electrical performance specifications. These laminates provide precise control over the dielectric constant (Dk) and low loss, while employing the same processing methods as standard epoxy/glass laminates. Unlike PTFE-based microwave materials, no specialized through-hole treatments or handling procedures are required, simplifying the manufacturing process.
Featuring a dielectric constant of DK 3.38 +/-0.05 at 10GHz and a dissipation factor of 0.0027 at 10GHz, the RO4003C PCB ensures accurate and reliable signal transmission. It exhibits a thermal conductivity of 0.71 W/m/°K, contributing to efficient heat dissipation. The PCB demonstrates a low coefficient of thermal expansion (CTE) with 11 ppm/°C for the X axis, 14 ppm/°C for the Y axis, and 46 ppm/°C for the Z axis. It also possesses a high Tg value of >280 °C, ensuring stability under elevated temperatures.
