High-Frequency PCB

Introduction to High-Frequency PCB

Blind Buried Circuits manufactures High-frequency PCBs, mainly used for high-speed communications, telecommunications, and RF microwave technology. The main reason to use HF PCBs for communication devices is that it offers a fast signal flow and 100 GHz or more frequency range based on the type of material. Most of the materials we use are of lower dielectric constant (Dk), lower dissipation factor (Df), and low levels of thermal expansion, which transmits electromagnetic waves with minimal losses.

Our PCB Capabilities

High-Frequency Printed Circuit Board Materials:

To achieve the optimal performance of our high-frequency PCBs at Blind Buried Circuits, our experienced manufacturing engineers select the suitable material depending on the application signal speed ranges and use the best substrate for your designs.


Regarding the cost of material, it is well known that Teflon is the most expensive material used to fabricate high-frequency PCBs. However, FR-4 tends to be slightly cheaper but limited to certain signal ranges. With limitations up to 1.6 GHz, FR-4 considerably drops the signal speed. In comparison, Teflon has a very low value for Dk, Df, and water absorption, making it survive in the most challenging environments.


Considering the frequency requirements, we use different substrates and Teflon for frequencies above 10 GHz. Our approved suppliers for high-frequency materials include Arlon, Taconic, Nelco, Isola, Rogers, and Teflon. They all are specialized in manufacturing low Dk and Df materials for high-frequency boards.
