Outstanding Performance Features
Superior Signal Integrity RF-35 enables excellent signal integrity for high-speed digital and analog circuits with its precise dielectric constant and tight material uniformity. The ultra-stable εr of 3.5 ensures consistent impedance control across the entire frequency spectrum.
Ultra-Low Loss Design RF-35’s ultra-low moisture absorption rate and low dissipation factor minimize phase shift with frequency, making it ideal for applications where every fraction of a dB matters.
Dimensional Stability The dimensional stability of RF-35 is achieved through the use of woven glass cloth in its design development, ensuring reliable performance across temperature variations and mechanical stress.
Enhanced Manufacturability RF-35 demonstrates excellent peel strength for 1/2 ounce and 1 ounce copper (even compared to standard epoxy materials), making rework readily available when needed.
