Definitions
- the present invention relates to an adhesive reel including a tape for circuit connection having a tape-like base material and an adhesive layer formed on one surface thereof, and a core on which the tape for circuit connection is wound.
- An anisotropic conductive film (ACF: Anisotropic Conductive Film) is used as a connection material for electrically connecting connection members having a large number of electrodes to produce a circuit connection body.
- the anisotropic conductive film maintains electrical continuity between opposing electrodes when connecting semiconductor devices such as ICs and LSIs and connected members such as packages to substrates such as printed wiring boards, LCD glass substrates, flexible printed substrates, etc.
- a connecting material that provides electrical connection and mechanical bonding so as to maintain insulation between adjacent electrodes.
- connecting materials such as non-conductive films (NCF: Non-Conductive films) are known.
- the connecting material includes an adhesive component containing a thermosetting resin, and conductive particles optionally mixed in the case of an anisotropic conductive film, and is formed on a substrate such as polyethylene terephthalate film (PET). It is formed into a film.
- An original material film of a film formed on a substrate is cut into a tape shape so as to have a width suitable for use, and this is wound around a core material to produce an adhesive reel (see Patent Document 1).
- Blocking is a phenomenon in which the adhesive layer is transferred to the back of the substrate when the tape for circuit connection is used by pulling it out of the reel.
- the necessary amount of adhesive layer can not be disposed at a predetermined position on the connected member, and there is a possibility that the electrical connection or mechanical fixation of the connection portion may be insufficient.
- the present inventors paid attention to the fact that the above phenomenon is likely to occur when the remaining amount of the circuit connecting tape wound on the reel was reduced, and examined the improvement measures. As a result, it has been found that this phenomenon may occur due to the joint between the circuit connection tape and the end tape.
- the end tape is a tape joined to the end of the circuit connection tape, and connects the circuit connection tape and the core.
- the end tape plays a role in reducing the adhesive layer which is discarded without being used. That is, the pressure bonding apparatus used for manufacturing the circuit connector has a predetermined distance from the mounting position of the adhesive material reel to the position where the pressure bonding operation is performed. Therefore, in the case of using a reel in which the circuit connection tape is directly wound around the core, the remaining adhesive layer is discarded without being used when the unwinding is completed and the reel is replaced with a new reel.
- the present invention has been made in view of the above-mentioned circumstances, and when pulling out the wound tape for circuit connection, the transfer of the adhesive layer to the back surface of the base material can be sufficiently suppressed and the connection reliability is excellent. It is an object of the present invention to provide an adhesive reel useful for producing a circuit connection.
- An adhesive reel comprises a tape for circuit connection having a tape-like base material and an adhesive layer formed on one surface of the tape, and a core on which the tape for circuit connection is wound.
- the tape for circuit connection is formed of an end tape joined to the end portion, and an adhesive layer is formed over the length of at least one winding of the core from the end of the tape for circuit connection toward the start end.
- a cover tape provided to cover the area.
- the circuit connection tape has a region where the adhesive layer is not formed over at least the length of one winding of the core from the end toward the beginning.
- the cover tape can be used to detect that the tape for circuit connection wound on the reel is small.
- the hue of the cover tape is preferably different from the hue of the adhesive layer.
- the circuit connecting tape and the end tape may be joined by a cover tape. That is, the cover tape may be extended to the end of the end tape to join the end of the circuit connection tape and the end of the end tape.
- the circuit connecting tape preferably includes an adhesive tape provided so as to cover the end portion and the end portion of the end tape.
- an adhesive tape and a cover tape may be used to bond the circuit connecting tape and the end tape.
- At least one surface of the end tape is preferably anti-slip processing.
- the transfer of the adhesive layer to the back surface of the base material can be sufficiently suppressed, and a circuit connection body with excellent connection reliability can be manufactured.
- FIG. 1 It is a perspective view which shows one Embodiment of the adhesive material reel which concerns on this invention. It is sectional drawing which shows the state with which the adhesive material reel of FIG. 1 was mounted
- FIG. 1 It is a schematic sectional drawing which shows an example of the circuit connection body in which circuit electrodes were connected. It is a figure which shows an example of the manufacturing method of a circuit connection body by a schematic sectional drawing. It is a schematic diagram which shows the terminal part of the anisotropic conductive tape which concerns on 2nd Embodiment of this invention. It is a schematic cross section which shows the process in which the anisotropic conductive tape which concerns on the comparative example 2 is pulled out from a reel.
- the adhesive material reel 10 shown in FIG. 1 includes a cylindrical core 1 and circular side plates 2 provided on both axial end faces of the core 1. As shown in FIG. 2, an anisotropic conductive tape 5 is wound on the outer surface 1 a of the core 1 to form a wound body.
- the adhesive reel 10 has an axial hole 10 a for mounting on the rotation shaft 25 a of the crimping device 25.
- the outer diameter of the winding core 1 is not particularly limited, but is preferably 4 to 15 cm in terms of handleability.
- the anisotropic conductive tape 5 includes a tape-like base 6 and an adhesive layer 8 formed on one surface of the base 6.
- the length of the base 6 is about 1 to 400 m, preferably 50 to 300 m.
- the thickness of the substrate 6 is about 4 to 200 ⁇ m, preferably 20 to 100 ⁇ m.
- the width of the substrate 6 is about 0.5 to 30 mm, preferably 0.5 to 3.0 mm.
