Abstract :
Space charge profiles of printed circuit boards used in the telecommunication industry were observed under dc electric fields with increasing temperature. Hetero charge distributions were formed in specimens made of aramid paper and epoxy resin, and the electric field near each electrode was enhanced. The results also suggest that the internal charge profile depends on the treatment of aramid papers.
