Product Description:

Engineered for mission-critical automotive radar systems (77GHz+), our double-sided PCB utilizes Rogers 4003C high-frequency laminate to deliver unmatched signal integrity and thermal reliability. This circuit board is purpose-built for ADAS (Advanced Driver Assistance Systems), collision avoidance, and autonomous driving sensors where millimeter-wave precision is non-negotiable.

Critical Features & Benefits:
✅ Rogers 4003C Core Material: Ultra-low dielectric loss (Df ≈ 0.0027 @ 10GHz) and stable Dk (εr = 3.38) ensure minimal signal distortion at 24GHz, 77GHz & 79GHz radar frequencies.
✅ Ultra-Low Z-Axis CTE (17 ppm/°C): Matches copper CTE to prevent via cracking & delamination under extreme automotive thermal cycling (-40°C to +150°C).
✅ Double-Sided Design: Cost-effective solution for complex RF routing + integrated control circuitry in compact radar modules.
✅ Moisture Resistance: Near-zero water absorption (<0.04%) maintains electrical stability in harsh environments.
✅ Automotive-Grade Reliability: AEC-Q200 compliant design principles for vibration/shock resistance and long-term durability.

Ideal Applications:

77/79GHz ACC (Adaptive Cruise Control) Radar PCBs

Blind Spot Detection (BSD) Sensors

Forward Collision Warning (FCW) Systems

Autonomous Vehicle Perception Modules

High-Resolution SAR (Synthetic Aperture Radar)
