Title: Controlled self assembly of anisotropic conductive adhesives based on ferromagnetic particles

Abstract: An anisotropic conductive adhesive (ACA) arrangement is disclosed, including a thermosetting resin disposed between a connector of a first structure and a connector of a second structure, and a plurality of ferromagnetic conductive particles dispersed through the thermosetting resin, wherein the plurality of ferromagnetic conductive particles form columns between the connector of the first structure and the connector of the second structure, and wherein a density of the ferromagnetic particles in the columns is substantially higher than a density of the plurality of ferromagnetic particles away from the columns.
