2-Layer RO4350B LoPro PCB 0.95mm Thickness High-Frequency Board for 5G & RF Systems
(All PCBs are custom-manufactured. Reference images and parameters may vary based on your design requirements.)
1. Overview of RO4350B LoPro 2-Layer PCB
Rogers RO4350B LoPro PCBs are advanced high-frequency circuit boards engineered for demanding RF and digital applications. Combining Rogers' proprietary low-profile copper foil technology with a robust dielectric core, these 2-layer rigid PCBs deliver exceptional signal integrity, thermal stability, and low insertion loss. Designed for 5G infrastructure, cellular base stations, and satellite systems, Rogers RO4350B LoPro substrate ensures precise impedance control and reliable performance in harsh environments. With a dielectric constant of 3.48 (±0.05 at 10 GHz) and copper-matched CTE, RO4350B LoPro PCB minimizes signal distortion while surviving extreme thermal shocks.

Why Choose This PCB?
RO4350B LoPro PCBs excel in high-frequency environments where signal integrity and thermal management are critical. Their low Z-axis CTE prevents via cracking under thermal stress, while the dielectric constant stability (±50ppm/°C from -50°C to 150°C) ensures consistent performance across temperature extremes. With FR-4-compatible fabrication processes and global availability, these boards reduce design risks and accelerate time-to-market.
