A high speed PCB is a printed circuit board designed to handle signals at higher frequencies, typically above 1 GHz. This capability allows for faster data transmission rates and improved performance in digital electronics. High speed PCBs are essential in devices such as smartphones, computers, and networking equipment, where rapid signal processing is crucial.

The design of high speed PCBs requires careful consideration of various factors, including trace width, impedance, and material selection. Unlike standard PCBs, which may function adequately at lower frequencies, high speed boards must address challenges related to signal integrity and electromagnetic interference (EMI). Understanding these differences is key for any PCB designer aiming to create effective high speed circuits.
