Claims13
An anisotropic, electrically conductive adhesive film comprising an electrically insulating adhesive, electrically conductive particles dispersed in the insulating adhesive, and transparent spherical glass particles dispersed in the insulating adhesive wherein the particle size distribution of the glass particles, defined by a cumulative volume ratio of the maximum particle size of the glass particles found in a cumulative volume that represent 75% of the particles by volume to the maximum particle size of the glass particles found in a cumulative volume that represent 25% of the particles by volume, is 1 to 2.
An electronic assembly comprising an electronic component bonded to a circuit substrate by an anisotropic, electrically conductive adhesive film, wherein the adhesive film comprises an electrically insulating adhesive, electrically conductive particles dispersed in the insulating adhesive, and transparent spherical glass particles dispersed in the insulating adhesive, wherein the particle size distribution of the glass particles, defined by a cumulative volume ratio of the maximum particle size of the glass particles found in a cumulative volume that represent 75% of the particles by volume to the maximum particle size of the glass particles found in a cumulative volume that represent 25% of the particles by volume, is 1 to 2.
