  An electrically conductive cement which when used to bond electrically conductive mating surfaces provides substantially stable conductivity characteristics under high humidity conditions; comprised of a carrier that provides a volumetric shrinkage of more than about 6.8% (vol.) and a conductive filler including agglomerates, particles, powders, flakes, coated nickel particles, and coated glass spheres, having size and surface characteristics that maintain stable electrical contact by forming a moisture resistant contact with an electrical component lead. The carrier having a volumetric shrinkage between the uncured and cured states of greater than about 6.8% (vol) appears to effect a compaction of the filler particles causing the particles to be forced into enhanced electrical contact with the surfaces to be connected and to provide a measure of compaction between the particles themselves to enhance particle-to-particle conduction. The shrinkage of the polymeric carrier during curing places the interior particles under compression with sufficient force to urge the particles into engagement with one another as well as to cause the particles to penetrate non-conductive oxides that may be present on a component lead.

  一种导电粘合剂，用于粘合导电配接表面时，可在高湿度条件下提供基本稳定的导电特性；由体积收缩率大于约 6.8%（体积分数）的载体和导电填料（包括团聚体、颗粒、粉末、薄片、涂层镍颗粒和涂层玻璃球）组成，导电填料的尺寸和表面特性可通过与电气元件引线形成防潮接触而保持稳定的电气接触。载体在未固化和固化状态之间的体积收缩率大于约 6.8%（体积分数），似乎会对填料颗粒产生压实作用，使颗粒被迫与待连接表面形成增强的电接触，并在颗粒本身之间提供一定程度的压实，以增强颗粒间的传导。固化过程中聚合物载体的收缩会使内部颗粒受到足够的挤压，从而促使颗粒相互接触，并使颗粒穿透元件引线上可能存在的非导电氧化物。
