Dielectric constant (DK) refers to the ratio of the capacitance of a material charged between electrodes to the capacitance of a vacuum capacitor with the same structure. It usually indicates the capacity of a material to store electric energy. The current direction through the electrical signal on the circuit board is usually alternating positive and negative, that is, the process of continuously charging and discharging the substrate. In exchange, the capacitance will affect the signal transmission speed. When DK is large, it means that the capacity of storing electric energy is large, and the transmission speed of electric signal in the circuit will slow down. When DK is small, it means that the capacity of storing electric energy is small, and the transmission speed of electric signal in the circuit will become faster
