摘要： An electrically conductive cement having substantially stable conductivity and resistance characteristics under high humidity conditions comprises a mixture of two epoxy resins with the proportion of each epoxy resin adjusted to provide a volumetric shrinkage in the mixture in the 4 to 16% and a conductive silver particular filler including agglomerates having size and surface characteristics that maintain stable electrical contact with an electrical component lead. The epoxy mixture is preferably a combination of a high-shrinkage epoxy resin and a lower-shrinkage epoxy resin in the appropriate amounts of each so as to produce the desired volumetric shrinkage characteristic. The conductive particle filler is preferably an admixture of silver flakes, silver powder, and an effective amount of silver agglomerates. The agglomerates are irregularly shaped particles having multiple surface indentations and recesses to produce many rough-edged salients or ridges and having a particle length, width, and thickness aspect ratio of about 1:1:1. An effective amount of such agglomerates appears to effect penetration of surface oxides when establishing the cemented connection as a result of the volumetric shrinkage of the polymeric carrier upon curing.

摘要： 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.
