Abstract
Electrically conductive elements on two substrates can be electrically interconnected by an adhesive tape containing electrically conductive equiax particles that are individually positioned in the adhesive layer in a predetermined pattern. Each particle is harder than the elements it is to interconnect, so that hand pressure causes the particles to penetrate into the elements, thus creating a reliable electrical connection. Particularly useful particles are glass beads having a metallic coating that is from 0.1 to 2 .mu.m thick.
