Abstract
An electrically conductive adhesive comprises electrically conductive particles mixed in a non-conductive base at such a mixing ratio that the conductive particles are not in contact with one another. When this adhesive is disposed between facing electrodes, it provides electric conductivity between the facing electrodes but maintains electric insulation in the lateral direction.
Claims5
An assembly comprising:
- a pair of members each having an array of electric conductors thereon, said members having respective portions thereof in superposed spaced-apart relationship such that terminal portions of the array of electric conductors on one member face respectively terminal portions of the array of electric conductors on the other member;
- and means adhering together said pair of members to electrically connect facing terminal portions of both arrays of electric conductors and electrically insulate adjoining terminal portions of both arrays of electric conductors, said means comprising an electrically non-conductive adhesive material adhering together said pair of members, and electrically conductive particles incorporated and mixed in said adhesive material, said particles being disposed in essentially a single layer and having a size sufficiently large with respect to the spacing distance between said members to electrically connect said facing terminal portions of both arrays of electric conductors, and said particles being spaced apart by said adhesive material distances sufficient to electrically insulate adjoining terminal portions of both arrays of electric conductors.
