Abstract
Abstract The inventive interconnector, which is used for electrically connecting two arrays of electrodes on two circuit boards, etc., is a striped sheet composed of alternately arranged strips of an insulating adhesive hot-melt resin and strips of a conductive adhesive hot-melt resin composition. The interconnector is prepared by stacking a film of the insulating resin coated on one surface with the conductive composition, integrating the stack into an integral block and slicing the block in a plane perpendicular to the surface of the stacked films. Alternatively, the interconnector is composed of a matrix of an insulating adhesive hot-melt resin and regularly distributed spots of a conductive adhesive hot-melt resin composition. Such an interconnector can be prepared by stacking alternately numbers of the above mentioned striped sheets and sheets of the insulating adhesive hot-melt resin one on the other, integrating the stack into an integral block and slicing the block in a plane perpendicular to the running direction of the conductive strips in the conductive sheets.
