Abstract: Double-sided reworkable pressure sensitive adhesive tape joins electronic device structures. The reworkable pressure sensitive adhesive tape has a pair of polymer carrier layers that are attached to each other using a thermoplastic adhesive. Opposing outer surfaces of the carrier layers are coated with pressure sensitive adhesive. The thermoplastic material that is used in attaching the carriers to each has a softening temperature that allows the thermoplastic material to be softened without significantly softening the carrier layers. When the thermoplastic material is softened, the structures that have been joined using the tape may be separated from each other. This divides the tape into two tape remnants. After cooling the tape remnants to restore cohesive strength to the pressure sensitive adhesive, the tape remnants can be cleanly peeled away from the structures. Additional reworkable tape may then be used to reattach the structures.
