This non-provisional U.S. patent application claims the benefit of priority under 35 U.S.C. §119 of Korean Patent Application No. 10-2006-0101026, filed on Oct. 17, 2006, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
BACKGROUNDWhen semiconductor chips are assembled as semiconductor packages, various types of wrapping materials may be used to transfer the semiconductor packages to a user safely. Conventionally, carrier tapes or trays may be used as the wrapping materials. The carrier tape protects the semiconductor packages included therein from external shocks, and allows the semiconductor packages to be handled more easily.
The user may withdraw the semiconductor devices from the carrier tape 10 to use the semiconductor packages. To do this, the cover tape 20 may be removed first, and the semiconductor devices included in the pockets 14 withdrawn. In
According to the conventional carrier tape 10, once the cover tape 20 is removed to withdraw the semiconductor devices, it may be impossible to use the cover tape 20 and carrier tape 10 again. As such, the conventional carrier tape may be discarded to become a cause of environmental contamination. Further, even if a defect occurs on only one portion of the plurality of pockets 14 and/or the cover tape 20, the entire carrier tape 10 and/or the cover tape 20 must be discarded.
SUMMARY OF EXAMPLE EMBODIMENTSExample embodiments may provide a carrier tape that may be recyclable so as not to become a cause of environmental contamination. Even when a defect occurs on recesses of a carrier tape, a corresponding part may be easily replaced. Thus, the carrier tape may be more economically and environmentally advantageous over the conventional art.
Example embodiments also may provide a method of wrapping semiconductor devices using the tape carrier.
According to example embodiments, there may be provided a carrier tape for receiving semiconductor devices, the carrier tape may include a frame tape having perforation portions, and a pocket. The pocket may have a recessed bottom, on which the semiconductor device may be received, and a stopper that may prevent the semiconductor device received in the recessed bottom from escaping from the pocket. The pocket may be capable of being attached/detached into/from the perforation portion.
A pair of stoppers facing each other may be disposed on an opening portion of the pocket. The semiconductor device may be separated by moving the stoppers so that the pocket and the carrier tape may be recycled.
The pocket may be inserted into the perforation portion to be attached into the frame tape.
The carrier tape may further include a reel, on which the frame tape may be wound.
A lip portion in parallel with the recessed bottom may be formed on at least a portion of the opening portion of the pocket with constant width. The lip portion may prevent the pocket from penetrating the perforation portion even if the pocket is forcefully inserted into the perforation portion of the frame tape.
The pocket may be removably inserted into the perforation portion of the frame tape, and the lip portion may be mounted on a peripheral surface of the perforation portion of the frame tape.
The stoppers may be disposed in parallel to the recessed bottom to prevent the semiconductor device from escaping from the pocket. The stoppers may be capable of rotating toward the recessed bottom and may be incapable of moving toward the opposite direction of the recessed bottom.
The pocket may be inserted into the perforation portion of the frame tape, and the pocket may include a protrusion at least on a side surface of the pocket for preventing the pocket from escaping from the frame tape.
According to example embodiments, there may be provided a method of wrapping semiconductor devices using a carrier tape, which may include a frame tape having perforation portions, and a pocket. The pocket may have a recessed bottom, on which the semiconductor device may be received, and a stopper that may prevent the semiconductor device received in the recessed bottom from escaping from the pocket. The pocket may be capable of being attached/detached into/from the perforation portion. The method may include attaching the pocket onto the frame tape, and inserting the semiconductor device into the pocket.

Referring to
A conventional carrier tape may have various widths according to the sizes of the semiconductor devices that are to be received, and a certain semiconductor device may only be received in a carrier tape having a corresponding width. However, according to example embodiments, the carrier tape 100 semiconductor devices of different sizes may be received by changing pockets 200 (

Referring to
Alternatively, the inner space in the pocket 200 may be adjusted according to the size of the semiconductor device that is to be received in the pocket 200. If the semiconductor device is small, a pocket having smaller inner space may be used to receive the semiconductor device, but still have the same outer appearance of the pocket 200. Therefore, the frame tape 100 may be used to receive semiconductor devices having various sizes to provide a more economical and easily automated alternative to the conventional carrier tape.
To attach the pocket 200 to the frame tape 100, the pocket 200 may be inserted into the perforation portion 110 of the frame tape 100.
In example embodiments, referring to
When the pocket 200 is inserted into the perforation portion 110 of the frame tape 100, the lip portions 230 of the pocket 200 may be mounted on peripheral surfaces of the perforation portion 110. Thus, the pocket 200 may be coupled to the frame tape 100.
To separate the pocket 400 from the frame tape 100, the edges of the frame tape 100 may be removed from the gap between the protrusion 440 and the lip portion 430. For example, side portions of the frame tape 100 may be extended to both side directions to separate the pocket 400, or both side surfaces 450 of the pocket 400 may be pressed to separate the pocket 400 from the frame tape 100.
Referring to
In
When the protrusion 440b is attached as above, the pocket 400 may be easily inserted into the frame tape 100. After inserting the pocket 400 into the frame tape 100, the other end portion of the protrusion 440b may be separated from the side surface 450 of the pocket 400 to prevent the pocket 400 from escaping from the frame tape 100. When the pocket 400 is to be separated, the other end may be pressed to contact the side surface 450 of the pocket 400 and the pocket 400 may be easily separated from the frame tape 100.
The carrier tape may further include a reel. The reel may be the reel 30 of
According to example embodiments, there is provided a method of wrapping semiconductor devices using a carrier tape receiving semiconductor devices, which may include a frame tape having perforation portions, and a pocket including a recessed bottom, on which the semiconductor device may be received, and a stopper preventing the semiconductor device from escaping from the pocket, and capable of being attached/detached into/from the perforation portion, the method may include attaching the pocket into the frame tape, and inserting the semiconductor device into the pocket.
Referring to
During insertion of the semiconductor device 500 into the pocket 200, the stoppers 230 may be folded toward the inside of the pocket 200, and then, unfolded. After inserting the semiconductor device 500 into the pocket 200, the stoppers 230 may be arranged in parallel with the recessed bottom of the pocket 200 to prevent the semiconductor device 500 from escaping from the pocket 200.
According to example embodiments, the carrier tape may be recyclable to be more environmentally friendly. Even if a defective portion is generated on the pocket, the corresponding portion may be easily replaced with a new one. Thus, it may be economically advantageous to use the carrier tape of example embodiments.
While example embodiments have been particularly shown and described with reference to the drawings thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of example embodiments as defined by the following claims.
