Semi flexible pcbselecting pcb materials for high-frequency applications
Understanding Dielectric Constant in High-Frequency PCB Materials When selecting printed circuit board (PCB) materials for high-frequency applications, understanding the dielectric constant (Dk) is crucial. The dielectric constant, also known as relative permittivity, measures a material’s ability to store electrical energy in an electric field. This property significantly impacts signal integrity, propagation speed, and overall performance…
