RO3006 PCB 25mil - The Perfect Choice for High-Frequency Applications

  • January 17. 2024

In the world of printed circuit boards (PCBs), choosing the right material is crucial for achieving optimal performance. One material that stands out from the rest is the RO3006 PCB 25mil. Manufactured by Rogers Corporation, this PCB is specifically designed to offer exceptional electrical and mechanical stability, making it the ideal choice for high-frequency applications. In this blog, we will delve deep into the features, benefits, and applications of this remarkable PCB.


The Rogers RO3006 PCB is made from ceramic-filled PTFE composites, which contribute to its outstanding performance. One of its key features is its dielectric constant (Dk) of 6.15 +/- 0.15 at 10 GHz/23°C. This stable Dk ensures consistent electrical properties over a wide range of temperatures, eliminating the step change in Dk that occurs in PTFE glass materials near room temperature. Additionally, the PCB has a low dissipation factor of 0.002 at 10 GHz/23°C, making it highly efficient in transmitting signals.

Another notable feature of the Rogers3006 PCB is its high thermal conductivity of 0.79 W/mK. This property allows for effective heat dissipation, making it suitable for applications that require thermal management. Moreover, the PCB has a high thermal decomposition temperature (Td) of over 500°C, ensuring its reliability under extreme temperature conditions. Additionally, with a moisture absorption rate of only 0.02%, the PCB remains stable and reliable even in humid environments.


The RO3006 high frequency PCB offers several benefits that set it apart from other PCB materials. Firstly, its uniform mechanical properties make it perfect for multi-layer board designs with a range of dielectric constants. This allows for greater flexibility in circuit design while maintaining consistent performance. Additionally, the PCB is suitable for use with epoxy glass multi-layer board hybrid designs, further expanding its applications.

The low in-plane expansion coefficient of the RO3006 25mil laminate PCB is another significant benefit. It matches closely with that of copper, enabling reliable surface mounted assemblies. This property is crucial for applications that are sensitive to temperature changes. Moreover, the PCB exhibits excellent dimensional stability, ensuring the integrity of the circuit over time.

Furthermore, the RO3006 printed circuit board is manufactured using a volume manufacturing process, resulting in economical laminate pricing. This makes it a cost-effective choice for large-scale production.
