The copper pcb manufacturing by Hitech, raw material is FR4 TG180 S1000-2 finished gold plating. The thickness of the copper foil is an important factor that affects the characteristic impedance. The greater wire thickness, the smaller impedance, but the range of change is relatively small. In other words, thin copper foil is used to make fine wires to increase or control impedance.
