What is the significance of impedance for PCB circuit board, and why should PCB circuit board make impedance? This paper first introduces what is impedance and the type of impedance, then introduces why PCB circuit board should make impedance, and finally expounds the impedancePCB Circuit BoardThe significance of the specific follow Xiaobian to understand.
What is impedance
In a circuit with resistance, inductance, and capacitance, the resistance to alternating current is called impedance. Impedance is commonly expressed as Z, which is a complex number, the real part is called resistance, and the imaginary part is called reactance. The blocking effect of capacitance on alternating current in the circuit is called capacitive reactance, the blocking effect of inductance on alternating current in the circuit is called inductive reactance, and the blocking effect of capacitance and inductance on alternating current in the circuit is generally called reactance. The unit of impedance is Europe.
