Description
High-speed circuit boards are circuit boards used for high-speed signal transmission. They are specially designed to process high-frequency and high-rate electrical signals to ensure the accuracy and stability of data during high-speed transmission. Their main characteristics include high frequency performance, low loss, and excellent heat dissipation.
