In the rapidly evolving landscape of Advanced Driver Assistance Systems (ADAS) and autonomous driving, signal integrity and thermal reliability are non-negotiable. The RO4700 Series High-Frequency 4-Layer PCB is an engineered solution specifically designed for the rigorous demands of automotive camera modules. By combining Rogers’ industry-leading ceramic-filled thermoset technology with a precision 4-layer build, this board ensures your imaging sensors deliver crystal-clear data under the most extreme road conditions.
Unrivaled Material Performance: Rogers RO4700
The heart of this PCB is the RO4700™ dielectric material. Unlike standard FR-4, RO4700 is a low-loss, ceramic-filled hydrocarbon material that offers superior high-frequency performance and mechanical stability. It provides a stable dielectric constant (Dk) across a wide temperature range, which is critical for automotive sensors that must operate reliably from frozen winters to blistering summer heat.
-
Low Dissipation Factor: Minimizes signal attenuation, ensuring high-speed video data from the CMOS sensor reaches the processing unit without distortion.
-
Thermal Management: With excellent thermal conductivity, this substrate effectively dissipates heat generated by compact, high-performance camera chips, preventing thermal throttling and sensor noise.
Precision Engineering for Automotive Integration
This 4-layer stack-up is optimized for the ultra-compact footprints required by modern automotive housings.
-
0.6mm Ultra-Thin Profile: The slim 0.6mm thickness allows for seamless integration into aerodynamic side-mirror cameras, compact rear-view housings, and sleek front-facing ADAS arrays.
-
1oz Finished Copper: This copper weight provides the perfect balance between high-current power delivery to the sensor and the fine-line precision needed for high-density interconnects.
-
Immersion Silver (ImAg) Finish: We utilize an Immersion Silver surface finish to provide a flat, planar surface for high-density SMT components. ImAg offers excellent conductivity and is ideal for high-speed signal paths, while also being environmentally friendly and compliant with RoHS standards.
Automotive-Grade Reliability
Automotive electronics face constant vibration, moisture, and thermal cycling. The RO4700 series is formulated to resist “CAF” (Conductive Anodic Filament) growth and offers a low Coefficient of Thermal Expansion (CTE) in the Z-axis. This ensures that via structures remains intact and electrical connections remain secure throughout the vehicle’s lifespan.
