Surface breakdown phenomenon of printed wiring board was investigated with increasing temperature from 23°C to 150°C. The experiment was carried out by do pulse voltage with the frequencies in the range of 50Hz to 150Hz. Printed wiring boards of epoxy resin laminate have been employed to investigate the effects of the surface temperature, electrode distance and the frequencies of applied voltage on the discharge quantity. The study revealed that the time to breakdown decreases with increasing the temperature, increasing the frequency of applied voltage and decreasing the electrode distance. The characteristics of discharge currents with increased temperature and the electrode distance were discussed by power spectral density of discharge current. The results show that the power spectral density of discharge currents increases with increasing the temperature, and decreasing the electrode distance.

Surface breakdown phenomenon of printed wiring board was investigated with increasing temperature from 23℃ to 150℃. The experiment was carried out by dc pulse voltage with the frequencies in the range of 50Hz to 150Hz. Printed wiring boards of epoxy resin laminate have been employed to investigate the effects of the surface temperature, electrode distance and the frequencies of applied voltage on the discharge quantity. The study revealed that the time to breakdown decreases with increasing the temperature, increasing the frequency of applied voltage and decreasing the electrode distance. The characteristics of discharge currents with increased temperature and the electrode distance were discussed by power spectral density of discharge current. The results show that the power spectral density of discharge currents increases with increasing the temperature, and decreasing the electrode distance.
