Rogers RO3003 PCB is one of the most advanced high-frequency circuit board materials available today. Designed with a ceramic-filled PTFE composite, this substrate delivers exceptional electrical, thermal, and mechanical performance, making it a preferred choice for engineers developing RF, microwave, and high-speed communication systems.
At KKPCB, we specialize in manufacturing custom Rogers RO3003 PCBs, providing high reliability and precision solutions for demanding electronic applications.
1. Overview of Rogers RO3003 High Frequency Materials
Rogers RO3003 is part of the RO3000™ series developed for commercial microwave and RF applications. It features a stable dielectric constant (Dk = 3.0 ±0.04) and an ultra-low dissipation factor (Df = 0.001), ensuring minimal signal distortion and low transmission loss even at frequencies above 20 GHz.
Unlike typical PTFE-based materials, RO3003 offers superior dimensional stability due to its CTE (Coefficient of Thermal Expansion) of 17 ppm/°C in the X and Y axes, which closely matches copper. This compatibility ensures excellent layer-to-layer registration and via reliability, even in thermally demanding environments.

4. Thermal and Mechanical Stability
Rogers RO3003 offers exceptional mechanical strength and thermal stability, making it reliable for both static and dynamic environments:
-
High Tg (>280°C) ensures consistent dielectric behavior under high thermal stress.
-
Low Z-axis expansion (24 ppm/°C) ensures reliable plated through-holes (PTH) and prevents delamination.
-
Dimensional stability (<0.07 mm/m) maintains layer alignment during fabrication and reflow processes.
This ensures consistent impedance control, minimal signal phase shift, and superior reliability across temperature ranges from -55°C to +150°C.
