Product Description

RO4830 Ultra-Thin 0.2mm PCB: High-Frequency Board with 4/5 Mils Trace/Space for 77GHz Automotive Radar
(All PCBs are custom-manufactured. Reference images and parameters may vary based on your design requirements.)



1. Product Overview
This ultra-thin 2-layer PCB utilizes Rogers RO4830 thermoset laminate, delivering exceptional 77GHz performance at FR-4 processing costs. Specifically engineered for automotive radar sensors (76-81GHz), this 0.2mm board features:

1. 77GHz Optimized: 2.2dB/inch insertion loss at mmWave
2. Cost Efficiency: 40-50% savings vs PTFE laminates
3. Thermal Stability: -30ppm/°C TCDk
4. Manufacturing Simplicity: Standard FR-4 processes

Certified to IPC-Class 2 and UL 94 V-0 standards.
