High-performance Advanced Driver Assistance Systems (ADAS) demand uncompromising signal integrity and thermal stability. The RO4700 0.6mm 1oz Immersion Silver 4-Layer PCB is an enterprise-grade solution specifically engineered for Automotive Surround View Camera Systems. Designed to bridge the gap between standard FR-4 limitations and the rigorous demands of high-frequency automotive sensors, this PCB ensures your imaging hardware operates with precision in the most volatile environments.
Advanced Rogers RO4700 Dielectric Strength
At the core of this circuit board is the Rogers RO4700™ series high-frequency material. Unlike traditional thermoset laminates, RO4700 is an antenna-grade material that provides a low dielectric constant ($D_k$) and a remarkably low dissipation factor ($D_f$). For 360-degree surround-view systems, this translates to minimal signal loss and reduced phase distortion, allowing for the crystal-clear, real-time data transmission required for autonomous parking and obstacle detection.
Precision Engineering for Automotive Integration
With a total thickness of 0.6mm, this 4-layer stackup is optimized for the compact, space-constrained housings of modern automotive camera modules. The 1oz (35µm) finished copper weight provides the perfect balance between high-density routing and thermal dissipation.
To ensure long-term reliability against oxidation and sulfurization, we utilize an Immersion Silver (ImAg) surface finish. This RoHS-compliant finish provides a superior flat surface for fine-pitch Surface Mount Technology (SMT) components, ensuring high-reliability solder joints that can withstand the constant vibration and thermal cycling inherent in automotive applications.

Why Choose This PCB for Surround View Systems?
-
Low Z-Axis Expansion: The RO4700 material features a low coefficient of thermal expansion (CTE) in the Z-axis, which protects plated through-holes (PTH) from fracturing during extreme temperature swings ($ -40°C$ to $+125°C$).
-
Signal Integrity: Optimized for high-speed video data, reducing EMI and cross-talk between the power and signal layers.
-
Durability: The Immersion Silver finish offers excellent shelf life and electrical performance, making it the preferred choice for high-speed digital interfaces like LVDS or Ethernet-based camera links.
