Capabilities — High Frequency PCBs

To achieve optimal high-frequency performance, we use specialized substrate materials tailored to the required signal speeds of the application.

From a cost perspective, FR4 is the most affordable option, while Teflon is the most expensive. However, FR4 has limited high-frequency performance, with significant signal degradation beyond 1.6 GHz.

With advancements in PCB materials, several new substrate types now offer excellent high-frequency performance. These materials, including Teflon, exhibit low Dk, low Df, minimal water absorption, and high durability, making them ideal for both rigid and flexible circuits operating in demanding environments.

For frequencies exceeding 10 GHz, Stream PCB uses these advanced substrate materials, ensuring superior signal integrity and reliability for high-frequency applications.
