Abstract
A conductive double-sided tape includes a conductive, nonwoven adhesive layer including an adhesive material, a nonconductive, nonwoven substrate having a plurality of passageways, and a plurality of conductive particles penetrating through the nonconductive, nonwoven substrate and the adhesive material. The nonconductive, nonwoven substrate is embedded in the adhesive material. The conductive particles have a D99 particle size larger than a thickness of the nonconductive, nonwoven substrate and the adhesive material.
