Abstract: Impedance design is an important part for PCB reliability design. This article will introduce design theory, theoretical arithmetic of Characteristic Impedance and strict impedance controlling. These are used to ensure impedance matching and achieve PCB reliability to make the product be in a steady state. Key words: Reliability; Characteristic
