Sensitivity of the resistance of adhesive joints formed of frequently used electrically conductive adhesives with isotropic electrical conductivity (ICAs) to loading with short current pulses of high amplitude has been examined. It has been found that the resistance increases with the increase of pulses amplitude and with the temperature at which experiments are carried out. It is assumed that the increase is caused by the increase of the thickness of insulating barriers between particles caused with chemical products originated by temperature degradation of resin is surroundings of contacts between particles. Heating of contacts is caused with the passing current.
