Rogers RO4350B Low Profile Material
Rogers RO4350B LoPro redefines cost-effective high-frequency design with its proprietary reverse-treated foil technology. This innovation bonds foil directly to standard RO4350B dielectric, delivering reduced conductor loss (and thus improved insertion loss) while retaining all key benefits of standard RO4350B:
FR-4 Process Compatibility: No specialized via preparation (e.g., sodium etch) required - uses standard epoxy/glass fabrication workflows to lower manufacturing costs and lead times.
Hydrocarbon Ceramic Composition: Combines low dielectric loss with mechanical stability, making it ideal for mixed-signal (RF + digital) applications.
Environmental Compliance: Lead-free process compatible and UL 94-V0 rated, meeting global safety and sustainability standards.

Key Material Features
Feature Specification
Dielectric Constant (Dk) 3.48 ± 0.05 at 10GHz/23°C
Dissipation Factor (DF) 0.0037 at 10GHz/23°C
Thermal Performance - Decomposition Temp (Td): >390°C
- Glass Transition Temp (Tg): >280°C (TMA)
Thermal Conductivity 0.69 W/mK
Coefficient of Thermal Expansion (CTE) - X-axis: 10 ppm/°C
- Y-axis: 12 ppm/°C
- Z-axis: 32 ppm/°C (-55 to 288°C)
Flammability Rating UL 94-V0
Additional Attributes CAF (Conductive Anodic Filament) resistant; lead-free compatible
Core Benefits
  • Ultra-Low Insertion Loss: Enables reliable operation beyond 40 GHz - critical for high-frequency applications like LNBs and base station antennas.
  • Reduced PIM: Minimizes passive intermodulation for clear signal transmission in cellular infrastructure, avoiding call drops or data degradation.
  • Thermal Resilience: Lower conductor loss improves heat dissipation, while high Tg/Td withstands lead-free soldering and high-temperature operating environments (e.g., server racks, outdoor antennas).
  • Copper-Matched CTE: X/Y-axis CTE (10/12 ppm/°C) matches copper, eliminating solder joint stress during thermal cycling - ensuring long-term reliability.
  • Design Flexibility: Supports multi-layer scalability (for future complex designs) and 2-layer cost-effectiveness, with CAF resistance for durability in humid environments.
Some Typical Applications
  • Digital applications such as servers, routers, and high speed back planes
  • Cellular base station antennas and power amplifiers
  • LNB's for direct broadcast satellites
  • RF Identification Tags
PCB application examples
Summary
The 2-layer PCB with Rogers RO4350B Low Profile material is a versatile, high-performance solution for RF and high-speed digital applications. By combining low conductor loss, FR-4 compatibility, ENEPIG finish, and industry-leading reliability, it addresses the key challenges of modern electronics - from signal integrity at 40+ GHz to cost-effective volume manufacturing.
