High Frequency PCB Based On 5mil


5870 Substrates PCB Board

Introducing our newly shipped RF PCB which is based on rogers RT duroid 5870 material. Rogers RT/duroid 5870 high-frequency laminates are composite materials made of PTFE reinforced with glass microfibers. These laminates offer exceptional high-frequency performance with a low dielectric constant (Dk). The random orientation of microfibers in the PTFE composite ensures consistent Dk values. RT/duroid 5870 laminates are ideal for applications requiring high frequency and broadband performance, where minimizing dispersion and losses is crucial.



Dielectric Constant: Boasting a low dielectric constant (Dk) of 2.33 with a tight tolerance of 0.02 at 10 GHz/23°C, the RT/duroid 5870 PCB ensures optimal signal integrity and minimized dispersion.


Dissipation Factor: With an impressively low dissipation factor of 0.0012 at 10 GHz, this PCB guarantees minimal signal loss, making it an ideal choice for high-frequency and broadband applications.


Temperature Stability: The temperature coefficient of dielectric constant (TCDk) of -115 ppm/°C ensures consistent performance even in varying temperature environments.


Moisture Absorption: Benefit from superior moisture resistance, as the RT/duroid 5870 PCB exhibits a moisture absorption rate of just 0.02%, providing reliability in high moisture environments.


Dimensional Stability: Enjoy excellent dimensional stability with a CTE (Coefficient of Thermal Expansion) of 22 ppm/°C (X-axis), 28 ppm/°C (Y-axis), and 173 ppm/°C (Z-axis), ensuring reliable performance under changing thermal conditions.

Isotropic Design: The RT/duroid 5870 PCB features an isotropic design, delivering uniform electrical properties across different directions.
