Rogers RO3003 PCB 1.78mm 3 Layer With Bare Copper

We are excited to announce our newly shipped 3-layer printed circuit board (PCB) featuring Rogers RO3003 high-frequency laminates. Engineered for commercial microwave and RF applications, RO3003 is a ceramic-filled PTFE composite known for its exceptional stability in dielectric constant (Dk) across varied temperatures and frequencies. This makes it particularly suitable for advanced applications such as automotive radar, ADAS, and 5G wireless infrastructure.

Key Features

Rogers RO3003 offers a dielectric constant of 3 ± 0.04 at 10 GHz and a low dissipation factor of 0.001, allowing for reliable performance in applications up to 77 GHz. With a thermal conductivity of 0.5 W/mK and moisture absorption of just 0.04%, this material ensures efficient heat management and durability. The coefficient of thermal expansion (CTE) is well-matched to copper, with values of 17 ppm/°C (X-axis) and 16 ppm/°C (Y-axis), ensuring excellent dimensional stability.
