3-Layer F4BM265 PCB 6.2mm Thick DK2.65 ENIG Wangling F4BM Laminates
Product Overview
Our newly shipped 3-Layer F4BM265 PCB is a high-frequency, high-reliability printed circuit board designed for demanding RF and microwave applications. With a 6.2mm thickness, low dielectric constant (Dk = 2.65), and ultra-low dissipation factor (0.0013 at 10GHz), this F4BM265 6.2 mm PCB is engineered for superior signal integrity, thermal stability, and long-term performance in critical environments.
Constructed using F4BM265 laminate—a PTFE-based material reinforced with fiberglass—this PCB offers enhanced dimensional stability, reduced signal loss, and excellent thermal management. It is ideal for radar systems, satellite communications, base station antennas, and high-frequency passive components.
