RO4350B PCB 2-layer 4mil Rogers 4350B High Frequency Laminate with Immersion Gold
Introduction
The 4mil RO4350B PCB is a high-performance, rigid printed circuit board designed for advanced RF and microwave applications. Manufactured using Rogers Corporation's proprietary RO4350B laminate, this PCB offers exceptional electrical performance, thermal stability, and cost-effectiveness. Rogers 4350B dielectric constant With 3.48 ±0.05 at 10 GHz/23°C and a low dissipation factor of 0.0037, the Rogers RO4350B PCB is engineered to meet the demanding requirements of modern wireless communication systems, automotive radar, and satellite technologies.
The Rogers 4350B material combines the electrical performance of PTFE/woven glass with the manufacturability of epoxy/glass, making it an ideal choice for multi-layer board (MLB) constructions. Its thermal coefficient of expansion (CTE) closely matches that of copper, ensuring excellent dimensional stability and reliable plated through-hole quality, even in severe thermal shock environments. With a high glass transition temperature (Tg) of >280°C and low water absorption of 0.06%, this PCB is built to withstand harsh operating conditions while maintaining consistent performance.
