/Electrically Conductive Tape With Monolayered Conductive Pressure Sensitive Adhesive
Abstract

An electrically conductive bonding tape includes a conductive first film between, and bonded to, conductive first and second adhesive layers. The first film and the first and second adhesive layers are conductive at least along a thickness direction of the bonding tape. Each of the first and second adhesive layers includes conductive particles dispersed substantially as a single layer in a substantially insulative adhesive material. The plurality of conductive particles in each of the first and second adhesive layers has an average particle size Pav and a standard of deviation Psd, such that Psd/Pav is less than about 0.2. Each of the first and second adhesive layers has an average thickness of no more than about 15% greater than the average particle size of the particles in the adhesive layer. An average surface roughness of opposing major first and second surfaces of the first film is less than 10 microns.
