摘要
阐述了导电胶的组成,介绍了渗流理论、隧道导电理论以及场致发射理论等电子导电胶导电原理,并根据导电方向的差异性,将导电胶划分为各向同性导电胶和各向异性导电胶两大类。对导电胶中填料形状与尺寸、复合型导电填料以及助剂等因素对导电胶导电性能影响的国内外研究进展进行了系统的介绍,并指出了电子导电胶的发展方向。
This paper describes electronic conductive adhesive （ECA） conductive principles consisting of seepage theory, tunneling theory and field emission theory. According to the difference of the conductive direction, ECA is divided into two categories： isotropic conductive adhesive and anisotropic conductive adhesive. Domestic and foreign research progress on the impact of the conductive particle shape and size, the composite of conductive fillers and additives on the conductivity of ECA are systematically introduced. The development direction of electronic conductive adhesive is also pointed out.
