Introducing the newly shipped RF PCB.Which is built is built on 31mil rogers DiClad 870 substrates. Designed with a focus on achieving lower dielectric constants, the DiClad 870 PCB offers exceptional electrical properties for a wide range of applications. It utilizes a unique composition of woven fiberglass and a higher ratio of PTFE content, resulting in reduced dielectric constants (Dk) and dissipation factors compared to other laminates in the DiClad series, all while maintaining a similar thickness.
Key Features:
The DiClad 870 PCB stands out with its impressive DK of 2.33 at both 10 GHz and 1 MHz, 50% RH. This ensures excellent signal transmission capabilities. Additionally, it exhibits an exceptionally low dissipation factor of only 0.0013 at 10 GHz and 0.0009 at 1 MHz, 50% RH, providing minimal signal loss.
Temperature fluctuations are not a concern as the DiClad 870 PCB offers a temperature coefficient of DK (TcDK) of -161 ppm/°C. It covers a wide temperature range of -10~140°C at 10 GHz, ensuring stable performance even under varying environmental conditions.
Moisture-related issues are minimized with this PCB, thanks to its moisture absorption rate of just 0.02%. This outstanding resistance to moisture ensures reliable operation in diverse environments.
The DiClad 870 PCB demonstrates excellent dimensional stability with a coefficient of thermal expansion (CTE) of 17 ppm/°C in the X-axis, 29 ppm/°C in the Y-axis, and 217 ppm/°C in the Z-axis. This stability guarantees precise performance and reliability.
