Unveiling the Impressive Properties of RT/duroid 6035HTC: Empowering High-Performance PCBs


The RT/duroid 6035HTC material, utilized in our PCB construction, boasts impressive properties that contribute to its high-performance capabilities. With a dielectric constant (ε) of 3.50±0.05 at 10 GHz/23℃, as determined by the IPC-TM-650 Clamped Stripline method, it ensures efficient signal transmission and reliable electrical characteristics. The dielectric constant (ε) design value stands at 3.6, making it suitable for frequencies ranging from 8 GHz to 40 GHz, as per the Differential Phase Length Method.


When it comes to dissipation factor, the RT/duroid 6035HTC exhibits a remarkably low value of 0.0013 at 10 GHz/23℃, according to the IPC-TM-650 test. This low dissipation factor ensures minimal signal loss and preserves signal integrity. Additionally, the thermal coefficient of the dielectric constant is measured at -66 ppm/℃ within the temperature range of -50℃ to 150℃, adhering to the IPC-TM-650 standard.

The RT/duroid 6035HTC material showcases excellent electrical insulation properties with a volume resistivity of 10^8 MΩ·cm and a surface resistivity of 10^8 MΩ, as determined by the IPC-TM-650 test. These characteristics guarantee effective electrical insulation and mitigate the risk of surface leakage.
