Rogers RT/duroid 5880 RO4450F 3-layer PCB 3.3mm Immersion Gold Finish Multilayer Board

Rogers RT/duroid 5880 RO4450F 3-layer PCB 3.3mm Thick Immersion Gold Finish Multilayer Board

Product Overview

Our newly shipped RT/duroid 5880 3-layer PCB is engineered for high-frequency applications requiring exceptional signal integrity, low loss, and superior dielectric stability. Designed with a 3.3mm thickness, this PCB features a 3-layer construction using RT/duroid 5880 and RO4450F bonding ply, ensuring uniform electrical performance across a wide frequency range. The immersion gold (ENIG) surface finish enhances corrosion resistance and provides a reliable surface for soldering and connectivity.

With a finished thickness of 3.3mm, immersion gold surface finish, and strict IPC-Class-2 compliance, this Rogers duroid 5880 PCB ensures reliability in high-frequency environments. The low dissipation factor (0.0009 at 10 GHz) and tight dielectric constant tolerance (±0.02) make it suitable for Ku-band and beyond.
