Abstract:
1. A board module having a plurality of electronic components mounted on a substrate via anisotropic conductive films, the module comprising: a glass substrate having a plurality of lines formed thereon; a first anisotropic conductive film affixed on the glass substrate; a second anisotropic conductive film or nonconductive film affixed on the first anisotropic conductive film; and electronic components disposed on the second anisotropic conductive film or nonconductive film, subjected to pressure bonding, and thereby connected to the lines at least via conductive particles included in the first anisotropic conductive film, wherein the first anisotropic conductive film has higher connection reliability than the second anisotropic conductive film or nonconductive film, the second anisotropic conductive film or nonconductive film has higher surface tack strength than the first anisotropic conductive film, and the first anisotropic conductive film has a higher melt viscosity than a melt viscosity of the second anisotropic conductive film or nonconductive film at a temperature for thermocompression bonding to connect the electronic components to the lines.
