High-Frequency Materials for PCB Design: Properties, Applications, and Selection Criteria
Abstract High-frequency printed circuit boards (PCBs) are essential components in modern wireless communication systems, radar, satellite technology, and high-speed digital applications. The performance of these PCBs heavily depends on the dielectric materials used, which must exhibit low dielectric loss, stable permittivity, and optimal thermal properties. This article explores the key characteristics of high-frequency PCB materials,…
