AI Overview
3.38) for signal layers and standard epoxy/glass (
4.5) for inner/bottom layers, enabling high-performance designs, such as 4-to-8 layer stacks for radar and telecommunications, at a lower cost than full PTFE boards.
Key Features & Advantages
- Performance + Cost: Combines low-loss, stable dielectric constant (3.38±0.05 at 10 GHz) of RO4003C with economical FR-4, suitable for high-frequency, cost-sensitive designs.
- Thermal Stability: Excellent thermal conductivity (0.71 W/m/°K) and high (), ensuring reliability in high-temperature environments.
- Fabrication: Compatible with standard FR-4 PCB fabrication processes (no sodium etch needed), simplifying manufacturing.
- Surface Treatment: Generally, immersion gold is used to ensure high-quality surface adhesion.
Typical Hybrid Stackup Structure
- Top/Bottom Layers (RO4003C): Used for RF/microwave signals.
- Inner Layers (FR-4): Used for power, ground, and digital signals to keep costs low.
- Structure: Common configurations include 4-layer (e.g., 20mil RO4003C + FR-4) or 6-layer designs.

What is the difference between FR3 and FR4 PCB?
FR3: Combines phenolic resin and paper with epoxy resin, providing better performance than FR2 but still inferior to FR4. FR4: Made of woven fiberglass with an epoxy resin binder, offering superior strength, thermal stability, and electrical insulation. It is the industry standard for most PCB applications.

What are the disadvantages of using FR4?
Limitations: Despite its advantages, FR-4 falls short in applications requiring high-frequency precision or superior heat management. Its higher dielectric loss is a disadvantage in high-speed circuits where signal integrity cannot afford to weaken.
