RO3003G2 2-Layer PCB 0.2mm Thin Board with Immersion Gold for Automotive Radar Applications
1.Introduction to RO3003G2 Material
RO3003G2 high-frequency laminates represent Rogers' advanced solution for millimeter-wave automotive radar needs. Developed based on industry feedback, these ceramic-filled PTFE composites feature:
Specially formulated resin/filler system for reduced insertion loss
Homogeneous construction with VLP ED copper (16/17/18 ppm/°C CTE)
Enhanced thermal stability (-35 ppm/°C Dk coefficient)
Ultra-low dielectric loss (0.0011 @10GHz)
This makes RO3003G2 ideal for 77GHz radar modules where signal integrity is critical.
2.Features
Thermal Stability: Tg of 257°C, withstands 288°C thermal stress.
Mechanical Strength: Bending strength of 410.2 N/mm² (machine direction).
Electrical Performance: Volume resistivity of 6.6×10? MΩ·cm, dielectric constant of 4.12.
Moisture Resistance: 0.11% absorption rate.
High-Frequency Suitability: Low dissipation factor (0.0072 at 1MHz).
3.Benefits
Industry-leading insertion loss performance
Minimized Dk variation in finished PCBs
Supports high-density via designs
Reliable operation in automotive temperature ranges
