ABSTRACT:
The invention is to an apparatus and method for re-working defective carrier tapes in which semiconductor devices are sealed in carrier tape by cover tape. A defective carrier tape (10) is moved through a track (16a) in a tape and reel machine (15). A defective cover tape (32a) is wound onto de-reel pulley (32) as it is removed from the carrier tape (10) through window (16b) in track (16a). A new cover tape (23) is applied to carrier tape (10) through window (16b) and is then sealed to carrier tape by heat elements (25). In the process, the carrier tape is unwound from a first reel (18) onto a second reel (19) without removing semiconductor devices from the carrier tape (10).
