HF PCBs

HF PCBs (high-frequency PCBs) are specially designed for use in high-frequency applications. Their purpose is to transmit and process signals at extremely high frequencies and lightning-fast data transfer rates with minimal loss.
The key to their performance lies in the use of special materials that offer extremely low loss and minimal electrical attenuation. These materials are designed to conduct signals across the PCB with virtually no loss, ensuring outstanding signal integrity.

Another important aspect in the manufacture of HF boards is the precise control of trace impedances. Tight tolerances for trace widths and spacing ensure consistent signal integrity, which is essential for reliable performance in high-frequency applications.
To optimize the cost of projects that can result from using expensive high-frequency materials, manufacturers often turn to so-called hybrid designs. These consist of a mixture of normal FR4 material pressed with a double-sided core of high-frequency material. In this way, the advantages of high-frequency technology can be utilized without breaking the budget.
