A circuit board assembly has a circuit board and a high-speed cable. The high-speed cable has two signal lines, a ground conductor, an impedance-reducing conductor, and a covering material. The signal lines, the ground conductor, and the impedance-reducing conductor are mounted through the entire high-speed cable. The covering material wraps the signal lines, the ground conductor, and the impedance-reducing conductor, and has a conductive layer and an isolation layer as an inner layer and an outer layer respectively. The conductive layer has multiple loops electrically connected to the ground conductor and the impedance-reducing conductor. Thus, the impedance in the covering material, the ground conductor, and the impedance-reducing conductor is decreased, which prevents from attenuating the signal intensity during transmission at high frequency.
