Abstract

An anisotropically conducting adhesive includes an adhesive base material; and conductive particles which are dispersed in the adhesive base material and which have provided on the surface of the conductive particles a separating agent comprised of at least one ligand which is selected from the group consisting of triphenylphosphine and propionic acid, which decomposes during use of the anisotropically conducting adhesive in an adhesion process and which is non-polymeric. A method for producing a bonded, electrically conductive connection between a plurality of strip connectors includes (a) providing the foregoing anisotropically conducting adhesive; (b) positioning strip connectors on opposite surfaces of the anisotropically conducting adhesive; (c) applying pressure to the anisotropically conducting adhesive and the strip connectors; and (d) decomposing the at least one ligand of the anisotropically conducting adhesive.
