Abstract
Abstract Electrically conductive adhesive tapes (10) comprising at least one carrier web (12) having a low-adhesion face bearing thereon an adhesive layer (18) having substantially uniform thickness and a Lap Shear Value from aluminum of at least 0.2 MPa, said tape being formed having a plurality of conductive particle (16) containing sections (14) selected from pockets and perforations, each section (14) containing a plurality of electrically conductive particles (16) in contact with the adhesive layer which is otherwise substantially free from electrically conductive material.
