RO4830™ Plus Laminates – High-Performance, Cost-Effective Millimeter-Wave PCB Material

October 16, 2025by kkpcba-Mason0

RO4830™ Plus thermoset laminates represent Rogers’ latest advancement in dielectric materials, specifically engineered for cost-sensitive millimeter-wave applications, including 76–81 GHz automotive corner radar sensors.

Electrical Performance Optimized for Automotive Radar

RO4830™ Plus laminates are woven-glass-free thermoset dielectric materials, providing:

  • Stable dielectric constant: ~3.03 at 77 GHz (measured via microstrip differential phase length method).

  • Low insertion loss: Only 1.5 dB/inch for 5 mil laminates, ensuring superior signal integrity in high-frequency radar circuits.

  • Reliable RF performance: Perfect for millimeter-wave automotive radar designs requiring minimal signal attenuation.

This combination of a low-loss thermoset resin system and very low-profile electrodeposited copper foil ensures high performance for radar PCB applications.

PCB Fabrication Advantages

RO4830™ Plus laminates are designed to serve as the cap layer on FR-4 multilayer boards, commonly used in 76–81 GHz automotive radar PCBs. Key fabrication benefits include:

  • Glass-free structure: Enhances laser drilling performance and CAF (Conductive Anodic Filament) resistance.

  • Compatibility: Works seamlessly with RO4400™ bondply and standard FR-4 epoxy/glass PCB processes.

  • PFAS-free: Environmentally friendly, compliant with modern safety standards.

  • UL-V0 flame rating and lead-free solder compatibility for reliable, safe manufacturing.

Key Features

  • Innovative thermoset resin platform

  • Very low profile (VLP) electrodeposited copper foil

  • PFAS-free, environmentally compliant

Benefits

  • Lower overall PCB manufacturing costs

  • Excellent insertion loss and laser drilling performance

  • High CAF resistance for long-term reliability

  • Consistent within-sheet dielectric constant for design predictability

RO4830™ Plus laminates combine high electrical performance, cost efficiency, and fabrication ease, making them an ideal choice for automotive radar sensor PCB designs operating in the 76–81 GHz range.
