The IsoClad 917 PCB is designed with Rogers' advanced non-woven fiberglass/PTFE composite materials, providing exceptional performance as a printed circuit board substrate. With a dielectric constant (Dk) of 2.17 or 2.20, IsoClad 917 laminates utilize a low ratio of non-woven fiberglass to achieve the lowest dielectric constant and dissipation factor available in its class. This unique formulation allows for flexibility in applications, making it suitable for conformal or wrap-around antennas. The longer random fibers and proprietary manufacturing process enhance the dimensional stability and dielectric constant uniformity, setting IsoClad 917 apart from its competitors.
Key Features
IsoClad 917 boasts impressive specifications, including a dielectric constant of 2.17 or 2.20 at 10 GHz and 23°C, along with a dissipation factor of 0.0013 under the same conditions. The temperature coefficient of dielectric constant (TcDK) is -157 ppm/°C, ensuring stability across a temperature range of -10°C to 140°C.
The laminate exhibits a strong peel strength of 10 lbs per inch and a low moisture absorption rate of just 0.04%. With a coefficient of thermal expansion (CTE) of 46 ppm/°C in the X-axis, 47 ppm/°C in the Y-axis, and 236 ppm/°C in the Z-axis, IsoClad 917 demonstrates excellent dimensional stability. Additionally, it meets UL-94 V0 flammability standards, ensuring safety in various applications.
