With the continuous improvement of chip integration,the interconnect wire spacing becomes smaller and smaller,so the device is more vulnerable to electrostatic damage.In order to improve the ability of the printed circuit board(PCB)to resist electrostatic discharge(ESD)and electromagnetic pulse(EMP)in practical applications,a polymer voltage-induced rheostatic film is prepared and embedded into the PCB to form a pulse absorption network,so that the entire circuit board has the ability to resist transient pulse and realize the whole system protection against ESD and EMP.The measured results of ESD protection show that compared with the ordinary circuit board,the full resistance pulse circuit board has faster response speed and higher release efficiency to the electrostatic pulses;the transmission line pulse(TLP)test results show that each point with the circuit board of the voltage-induced rheostatic film has the overvoltage pulse absorption capacity,and the current discharge capacity can reach more than 50 A.
