With the increase of signal transmission frequency,the problem of signal integrity of transmission lines has become more and more prominent.In this paper,the effects of nicks,protrusion,circuit repairing on the electrical performance of signal transmission lines are studied.The results show that circuit nick and open have little effect on the impedance,insertion loss and return loss of transmission lines,but with the increase of the number of nicks and opens,they gradually have an impact on the return loss,and the impedance of both the nicks and opens will show abnormal mutations and become smaller after circuit repairing.With the increase of the number of repairing points,the influence of circuit repairing on insertion loss and return loss increases gradually.
