  • Patent number: 5667073
    Abstract: The present invention provides a carrier tape for storage use of super-miniaturized electronic components, by which the reflection of irradiated light which might cause detection errors cab be prevented, the product inspection can be performed easily and quickly, and number of stored pieces and remaining un-used pieces can be easily and quickly counted, when the presence or absence of deformation--which might take place on the lead portion of the electronic components being stored in the carrier tape--is examined by the optical equipment on the lead portion kept on the carrier tape. The surface of said base component can be treated to form a film to prevent the light reflection or to absorb the light, such as by painting with resins or ink which doesn't reflect the light, or by immersion. Alternatively, the color of the base component is selected to be black.

  • Patent number: 5025923
    Abstract: A number of holes for individually receiving small-sized electronic parts such as chip capacitors and ceramic capacitors are formed in a strip of carrier tape to preserve these parts. The carrier tape is made of a strip of base material and a strip of double-sided adhesive tape stuck on one surface of the base material such that the area of each portion of the adhesive layer exposed through the holes is smaller than the area of each hole. The base material is made of an electrically conductive material. Alternatively, the base material may be made of a nonconductive material and the surface may be treated so as to be electrically conductive. Incisions are formed in the adhesive layer to facilitate removal of the adhesive in withdrawing the electronic parts from the tape. When the electronic parts are inserted in the holes, they are stuck on the adhesive layer, and then the tape is wound on a reel for storage.

  • Patent number: 4568416
    Abstract: Small-size electronic parts having leads are packaged with a carrier tape composed of a tape base having tape feed holes and a tape body of electrically conductive or nonconductive formed plastic attached to one side of the tape base. The carrier tape is unreeled from a supply reel, and the leads of the electronic parts are caused to pierce an upper surface and one side or both sides of the tape body. The carrier tape with the electronic parts retained on the tape body is wound around a takeup reel. With the method of the invention, small-side electronic parts with long leads can easily be packaged with a tape, the packaged electronic parts can easily be shipped and stored, and the electronic parts can easily be detached form the carrier tape.

  • Patent number: 4306928
    Abstract: A rolled strip of adhesive mounted on a reel is unrolled and punched with a cutter pressed against it or by passing between a punching roll and a receiving roll, the punched part being affixed to a band-shaped film of paper or plastic. The film having had a part of the punched adhesive pasted on it is wound up on a winding reel and the punched excess adhesive is wound up on another winding reel.
