IsoClad 917 High Frequency PCB Flexible Low Loss RF Circuit Material

August 27, 2025

Introduction to IsoClad 917 High Frequency PCB

Rogers IsoClad 917 laminates use a unique non-woven fiberglass and PTFE composition to achieve the lowest dielectric constant and dissipation factor in their class. This innovative reinforcement allows the material to be bent, making it ideal for conformal or wrap-around antenna applications. The proprietary manufacturing process and longer random fibers provide superior dimensional stability and consistent dielectric properties compared to similar materials.

Key Features of IsoClad 917 PCB

Low Dielectric Constant (Dk) of 2.17 or 2.20 with tight tolerance (±0.03)
Ultra-Low Dissipation Factor of 0.0013 at 10 GHz for minimal signal loss
Highly isotropic properties across X, Y, and Z axes for uniform performance
Low Moisture Absorption of 0.04% for reliable operation in varied environments
Enhanced flexibility compared to traditional woven fiberglass materials
