ABSTRACT:
An interconnecting means is comprised of one or more conductive ink conductors screen printed onto a first substrate, the conductive ink being comprised of an insulating polymer medium having first and second groups of conductive particles therein, and an insulating layer of flowable adhesive in covering relationship to the conductors. The first group of particles are finely divided particles which are suspended in the medium and form a continuous conductive path along the length of the conductor. The second group of particles are agglomerates of large particles which are randomly scattered throughout the conductive path and project above the surface of the medium. Interconnection is effected by positioning the first substrate conductors in an overlapping conducting relationship to the conductors on the second substrate such that the flowable adhesive is deposited between the two substrates and applying pressure to the positioned conductors and surrounding areas. The adhesive flows from the positioned areas, exposes the protruding agglomerates, thus bringing the agglomerates into contact and electrical interconnection with the second substrate conductors accompanied by the adhesion of the remaining first substrate surface to the surface of the second substrate.
