What are The Materials Used to Make High Frequency PCB?

The performance of HF boards in wireless or other high frequency scenarios is dependent on the substrate material. For many applications, the use of multilayer FR4 materials improves dielectric performance. Commonly used boards when manufacturing HF PCBs include Rogers, ISOLA , Taconic, Panasonic, and TAYO boards.

High-frequency board parameter characteristics:

 a, The coefficient of thermal expansion of the HF PCB substrate and copper foil must be the same, if it is not the same, it will cause the copper foil to separate in the process of hot and cold changes.

 b, High frequency circuit board substrate water absorption should be low, high water absorption will cause the dielectric constant and dielectric loss in moisture.

 c, High frequency circuit board substrate dielectric constant (Dk) must be small and stable, generally speaking, the smaller the better, the signal transmission rate and the square root of the material dielectric constant is inversely proportional to the high dielectric constant is likely to cause signal transmission delays.

 d,  High frequency circuit board substrate material dielectric loss (Df) must be small, which mainly affects the quality of the signal transmission, the smaller the dielectric loss so that the signal loss is also smaller.

 e, High frequency circuit board substrate materials, heat resistance, chemical resistance, impact strength, peel strength must also be good. Currently more used high-frequency circuit board substrate is fluorine dielectric substrate, such as polytetrafluoroethylene (PTFE), usually known as Teflon, usually used in more than 5GHz. There are also FR-4 or PPO substrates, which can be used for products between 1GHz and 10GHz.

HF PCB are generally used in radar systems, satellites, antennas, cellular telecommunication systems-power amplifiers and antennas, live satellites, E-band point-to-point microwave links, Radio Frequency Identification (RFID) tags, airborne and terrestrial radar systems, millimeter-wave applications, missile guidance systems, space satellite transceivers, and other fields.
