Product Description

High-Performance 6-Layer RO4350B+FR-4 PCB with 1.0mm Thickness for 5G, Automotive Radar & RF Applications
(All PCBs are custom-manufactured. Reference images and parameters may vary based on your design requirements.)
 

1. Overview of RO4350B+FR-4 6-Layer PCB

This advanced 6-layer rigid PCB combines Rogers RO4350B high-frequency laminate with High Tg 170°C FR-4 to deliver exceptional performance for demanding RF and microwave applications. Designed for 5G base stations, automotive radar systems, and satellite communication devices, it offers ultra-low signal loss, impedance control (50Ω on top layer), and superior thermal stability (Tg >280°C). The hybrid stackup leverages RO4350B PCB's low-loss ceramic-hydrocarbon composite for critical RF layers and cost-effective FR-4 for internal cores, ensuring optimal electrical performance while maintaining FR-4-like manufacturability. With a compact 50mm x 38mm footprint and 1.0mm total thickness,  RO4350B with FR-4 PCB is engineered for high-density, high-reliability designs in harsh environments.
