Introducing a 2-layer rigid PCB made of IsoClad 917.
IsoClad 917, a Rogers laminates product, revolutionizes printed circuit board substrates with its non-woven fiberglass/PTFE composites. With a dielectric constant (Dk) of 2.17 or 2.20, IsoClad 917 offers the lowest Dk and dissipation factor in its class. Engineered with a low ratio of non-woven fiberglass/PTFE, this laminate delivers remarkable performance and dimensional stability for a wide range of applications.
Key Features of IsoClad 917:
Low Dk and Dissipation Factor: IsoClad 917 boasts a Dk of 2.17 or 2.20 at 10 GHz/23°C, ensuring reliable signal transmission and minimal energy loss. With a dissipation factor of 0.0013 at 10 GHz/23°C, this laminate minimizes signal attenuation, resulting in efficient signal integrity.
Thermal Stability: IsoClad 917 offers a TcDK of -157 ppm/°C ranging from -10°C to 140°C, ensuring consistent electrical performance across varying temperature conditions. This stability makes it ideal for applications where temperature fluctuations are common.
Strong Peel Strength: With a peel strength of 10 lbs. per inch, IsoClad 917 provides excellent adhesion and reliability, ensuring the integrity of the PCB even under demanding conditions.
Low Moisture Absorption: IsoClad 917 exhibits low moisture absorption of 0.04%, making it suitable for applications in humid environments without compromising its electrical performance or dimensional stability.
Isotropic and Dimensionally Stable: The non-woven fiberglass reinforcement of IsoClad 917 provides isotropic properties, ensuring uniform electrical performance in all directions. Additionally, the longer random fibers and proprietary manufacturing process contribute to greater dimensional stability and dielectric constant uniformity, surpassing competitors in similar classes.
