In the rapidly evolving world of high-frequency electronics, the demand for reliable and high-performance printed circuit boards (PCBs) is greater than ever. At bicheng, we specialize in delivering cutting-edge PCB solutions tailored to meet the needs of advanced RF and microwave applications.

Why Choose Rogers RO3003?
Rogers RO3003 laminates are engineered to provide exceptional stability in dielectric constant (Dk) across a wide range of temperatures and frequencies. Unlike traditional PTFE glass materials, RO3003 eliminates the step change in Dk near room temperature, making it an ideal choice for high-frequency applications such as:

Automotive radar systems (77 GHz)

Advanced Driver Assistance Systems (ADAS)

5G wireless infrastructure (mmWave)

Dielectric Constant (Dk): 3.00 ± 0.04 at 10 GHz/23°C

Dissipation Factor (Df): 0.001 at 10 GHz/23°C

Thermal Conductivity: 0.5 W/mK

Moisture Absorption: 0.04%

Thermal Decomposition Temperature (Td): > 500°C

Coefficient of Thermal Expansion (CTE):

X-axis: 17 ppm/°C

Y-axis: 16 ppm/°C

Z-axis: 25 ppm/°C

Benefits of RO3003-Based PCBs

Low Dielectric Loss: Ideal for applications up to 77 GHz, ensuring minimal signal loss and superior performance.

Excellent Mechanical Properties: Reliable stripline and multi-layer board constructions with uniform mechanical properties across a range of dielectric constants.

Stable Dielectric Constant: Ensures consistent performance in bandpass filters, microstrip patch antennas, and voltage-controlled oscillators.

Low In-Plane Expansion Coefficient: Matches copper, enabling reliable surface-mounted assemblies and excellent dimensional stability.

Cost-Effective: Volume manufacturing processes make RO3003 laminates an economical choice for high-frequency applications.
