  • Patent number: 5594985
    Abstract: The invention is to an extractor for removing pins from storage tubes having a plurality of electronic semiconductor devices therein. A movable arm has an extractor pin on one end and is pivotally mounted to a frame on the other end. A head assembly for receiving a storage tube with a pin therein is moved under the extractor pin, actuating a solenoid for causing the movable arm to move the extractor pin toward and forcing the pin to be ejected from the storage tube so that the semiconductor devices can exit the storage tube.

  • Patent number: 5575136
    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).
