The Rogers RO4003C laminate is the highlight of this PCB, combining ceramic-filled hydrocarbon materials with woven glass reinforcement. This material provides the electrical performance of PTFE laminates while offering the manufacturability of standard epoxy/glass materials, but at a much lower cost.

Features of RO4003C:

Dielectric Constant (Dk): 3.38 ± 0.05 at 10GHz, ensuring precise and stable signal propagation.

• Dissipation Factor (Df):
  • 0.0027 at 10GHz
  • 0.0021 at 2.5GHz, minimizing energy loss.

• Coefficient of Thermal Expansion (CTE):
  • X-axis: 11ppm/°C
  • Y-axis: 14ppm/°C
  • Z-axis: 46ppm/°C
  • Low Z-axis CTE ensures reliable plated-through-hole quality, even under severe thermal shock.

• Moisture Resistance: Absorbs only 0.06% moisture, ensuring consistent performance in humid conditions.
• Thermal Conductivity: 0.71 W/mK, improving heat dissipation in high-power systems.
• Operating Temperature: Stable from -40°C to +85°C, making it suitable for various environments.

Benefits of RO4003C:
