Protection of spacecraft electronics against ESD effects using nanoconductive insulators

This paper develops the concept of possibility of using nanoconductive dielectrics in printed circuit boards instead of traditional ones. The symmetrical multivibrator was taken as an example of typical digital device and the computer simulations were performed using the LTspice software. Nanoconductive dielectrics have less electrificability, thus provide fewer electrostatic discharges (ESD) caused by the action of electron irradiation. Based on the results of computer simulations and calculations the dielectric parameters of the printed circuit board for which ESD are physically impossible were determined. It was shown that the change in the output parameters of the multivibrator does not exceed 5%. Therefore, it is possible and necessary to use nanoconductive dielectrics in the on-board radio electronic systems and equipment of space vehicles. According to our data, such dielectrics discharge-free, also conductivity raised to 10^-9 Ω^-Ω^-1 does not affect the operation of the electronics.
