Patent ID: 8816807

Claim:
An anisotropic conductive adhesive (ACA) arrangement, the ACA arrangement comprising: a thermosetting resin disposed between a connector of a first structure and a connector of a second structure; a plurality of ferromagnetic conductive particles dispersed through the thermosetting resin, wherein the plurality of ferromagnetic conductive particles are uniformly dispersed to form columns between the connector of the first structure and the connector of the second structure, and uniformly dispersed to form columns between the first structure and 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; interpad void regions substantially void of ferromagnetic conductive particles between the columns that are formed between the connectors of the first and the second structures and the columns formed between a neighboring set of connectors; and interpad void regions substantially void of ferromagnetic conductive particles between the columns that are formed between the connectors of the first and the second structures.
