What circuit boards are needed for 5g base stations

Which PCB material should be used for 5G?

The choice of PCB material for 5G applications depends on the frequency, power level, circuit size and function. Designers have choices for sub-strate materials from basic epoxy/glass (FR-4), mid-loss materials and, ultimately, high end microwave/millimeter wave materials.

What should be considered when designing a 5G PCB stack-up?

Material considerations will be the top aspect that will have to be evaluated for designing and building the high frequency PCB stack-up. The 5G PCB will have to address all the specifications when carrying and receiving signal transmissions, pro-viding electrical connections, and offering controls for specific functions.

How does PCB material affect 5G design?

PCB material parameters such as copper surface roughness, dielectric constant variations, thermal dissipation, passive intermodula-tion, coeficient of thermal expansion and thickness variations will affect 5G designs more than previous generations that had less stringent performance criteria.

Can a PCB withstand 5G?

PCB materials used for dielectric materials and core substrate layers will need to adequately handle the high speeds required for 5G technology. If the materials are inadequate, copper trace peeling, delamination, shrinking, and warping can result as problems that can cause deterioration of the PCB.
