Abstract

Regarding mechanism of electrical conduction through anisotropically conductive adhesive films (ACF), one model was already proposed by the authors. It was that there were two kinds of electric current passing through ACF: one passing through electrically conductive particles and the other passing through direct contacts between circuits; the current passing through conductive particles did not change so much even after high temperature and high humidity treatment but the current passing not through conductive particles significantly reduced after the treatment mentioned above. In this paper the expression of the relationship between electrical resistance and number of particles on a terminal is obtained by least square method. The above-mentioned two kinds of electrical resistance are figured out one by one with use of the expression. The proposed model is proved by it.
