<p>1477780 Electrical connections SEIKOSHA KK 30 July 1975 [14 Aug 1974 (2)] 31906/75 Heading H2E An assembly comprises a pair of members 1, 2 having portions in superposed spaced apart relationship, each member having an array 4a, 5a of electric conductors, terminal portions of one array facing those of the other member, and connecting means which adhers the members together so as to electrically connect facing terminal portions and electrically insulate adjacent portions. The connecting means comprises an electrically non-conductive adhesive material 7 having incorporated and mixed therein electrically conductive particles 8. The particles 8 are disposed in substantially a single layer and have a size sufficiently large with respect to the spacing of the members to connect the facing terminals and are spaced sufficiently by the adhesive material so as to electrically insulate adjacent terminals. As described, the particles 8 have substantially the same spherical shape and diameter and constitute less than 60% by volume of the connecting means. Insulating particles and/or electrically conductive fine particles may also be incorporated in the material 7, these particles having a size smaller than that of particles 8. The conducting particles may be one or more of the following powders: carbon, silicon carbide, reduced silver,-gold, palladium/silver, nickel and indium. The insulating particles may be one or more of: aluminium oxide, yittrium oxide, calcium carbonate, glass and plastics. The connecting means may be formed as a tape (Figs. 5 and 6, not shown) when the adhesive material may be of the type that is molten when heated, for example polyethylene terephthalate, polyethylene fluoride and polyamide (nylon), and the members being connected may be a printed circuit and a flat cable or a printing plate and a large size integrated circuit.</p> |
