Abstract

An electrically conductive adhesive layer includes an adhesive material; a plurality of electrically conductive first particles dispersed in the adhesive material and having a first shape; and a plurality of electrically conductive second particles dispersed in the adhesive material and having a second shape different from the first shape. A ratio of a total weight of the first particles to a total weight of the second particles is in a range from about 2 to about 10. The adhesive layer has an average thickness in a range from about 5 micrometers to about 35 micrometers. An electrical conductance of the adhesive layer in a thickness, but not in an in-plane, direction is at least 5% greater than a comparative adhesive layer having the same construction except that it does not include the second particles.
