The evolution of Advanced Driver Assistance Systems (ADAS) demands hardware that can process complex environmental data with zero latency and high precision. The RO4360G2 1.6mm 2oz ENIG 4-Layer Automotive Collision Avoidance Radar PCB is engineered specifically to meet these rigorous demands, providing a stable, high-thermal-conductivity platform for microwave and millimeter-wave applications.
Optimized for Automotive Collision Avoidance
In the realm of automotive safety, signal integrity is non-negotiable. This PCB utilizes Rogers RO4360G2 thermoset laminate—a ceramic-filled hydrocarbon material designed to bridge the gap between performance and manufacturability. With a dielectric constant ($Dk$) of 6.15, it allows for significant circuit miniaturization, making it ideal for compact radar modules integrated into bumpers and side-mirrors.
The 4-layer stackup is meticulously designed to support 24GHz to 77GHz radar sensors, ensuring that collision avoidance systems can accurately detect objects, calculate distances, and trigger emergency braking in milliseconds.

Why Choose RO4360G2 for Radar Applications?
Superior Thermal Management
With a thermal conductivity of 0.81 W/m/K, the RO4360G2 outperforms standard FR-4 materials by a wide margin. In the high-heat environment of a vehicle’s engine bay or exterior housing, this PCB effectively dissipates heat generated by power amplifiers and high-speed processors, preventing thermal throttling and maintaining signal accuracy.
Enhanced Signal Integrity with ENIG Finish
The ENIG (Electroless Nickel Immersion Gold) surface finish provides a perfectly flat mounting surface for fine-pitch components and Ball Grid Arrays (BGAs) commonly found in radar chipsets. Unlike HASL, ENIG ensures consistent signal transition at high frequencies, reducing parasitic capacitance and maintaining the tight tolerances required for 4-layer high-frequency designs.
Rigid and Reliable 4-Layer Stackup
The 1.6mm thickness provides the mechanical strength necessary to withstand the high-vibration environment of automotive use. By utilizing a 4-layer configuration, we provide dedicated planes for power and ground, significantly reducing electromagnetic interference (EMI) and crosstalk—critical for the sensitive receivers in collision avoidance hardware.
