Definitions
- the present invention relates to a sheet for an embossing tape used as a material for an embossing tape for packaging chip parts, I (:, electronic parts, etc.).
- Injection trays, vacuum forming trays, magazines, embossed carrier tapes, etc. are used as packaging forms for chip parts, I-electronic parts, etc., and embossed carriers are used to improve mounting efficiency. Tapes are widely used. However, in recent years, electronic components have become more complex, more precise, and smaller, and the packaging and mounting of electronic components has also become faster, resulting in the problem that the embossed carrier tape is broken during high-speed mounting.
- the present invention solves such a problem.
- the present inventors have analyzed the mechanism of the fracture of the embossed carrier tape and found out that the fracture is caused by tearing from the flange corner or sprocket hole of the embossed bottle. It was just. Disclosure of the invention
- the present invention relates to an embossed carrier tape sheet having a tear strength according to j]: s (Japanese Industrial Standards) 1 K 1 7 8 8-3 of 105 N / mm or more.
- Sheet of the present invention JIS- K- 7 1 2 8- 3 by tear strength should be at 1 0- 5 N / mm or more, c tear strength 1 properly is 1 1 5 NZmm more preferred 0 If the thickness is less than 5 NZmm, when the tape is used as an embossed carrier tape, it is easily broken such that the sprocket hole or the flange corner at the top of the pocket is torn.
- the thickness of the sheet is not limited as long as the tear strength by IS-K1 7 1 2 8-3 is not less than 105 N mm2, preferably in the range of 0.1 to 3.0 mm It is. If the overall thickness is less than 0.1 mm, the strength of the pocket part obtained by molding the sheet as a packaging container is insufficient, and if it exceeds 3.0 mm, air pressure molding, vacuum molding, hot plate Molding such as molding becomes difficult.
- the structure is not particularly limited, whether it is a single layer or a multilayer composed of two or more layers.
- a preferred structure is a single layer that is entirely conductive.
- One having a base material layer and having a conductive layer on at least one surface is also one of the preferable structures.
- Most preferred is a three-layer structure in which conductive layers are laminated on both surfaces of the base material layer.
- the sheet of the present invention preferably has at least one surface that is in contact with the electronic component.
- the sheet of the present invention does not necessarily have to be conductive depending on the type of electronic components to be stored, but in many cases the sheet is conductive to prevent the electronic components from being damaged by static electricity. Is desirable.
- the conductivity of the surface is less than 10 12 ⁇ , preferably in the range of 10 12 to 10 4 ⁇ .
- a resin having conductivity in the conductive layer for example, a conductive resin made of a thermoplastic resin and carbon black, a conductive inorganic filler, conductive fibers, or the like may be used.
- an antistatic agent may be used on the surface, or may be used in combination with a conductive resin.
- the sheet of the present invention can use a thermoplastic resin.
- Thermoplastic resins include polyvinyl chloride resin, polyester resin, polystyrene resin, and A
- BS resin Polypropylene resin, Polyethylene resin, Polyphenylene -In addition to tellurium resin and polycarbonate resin, various copolymers containing styrene, ethylene, propylene, vinyl chloride, etc. as main components are listed, and these can be used alone or in combination.
- resins may have conductive fillers such as carbon black, antistatic agents, plasticizers and other processing aids, various reinforcing agents, anti-glare agents, inorganic fillers, etc. Etc. can be added.
- thermoplastic resin As a method of processing the above-mentioned thermoplastic resin into a sheet shape, there are known extrusion molding, calendar molding, and the like. In the case of further multilayering, a feed block using a plurality of extruders is used. It is possible to use various methods such as a hot-dip method, a multi-manifold method, an extruded laminating method, a dry laminating method, and a gravure coating method.
- the sheet can be formed into an embossed carrier tape by forming it into an embossed shape by a forming method such as pressure forming, vacuum forming, hot plate forming or the like.
- a forming method such as pressure forming, vacuum forming, hot plate forming or the like.
- the sheet is slit to a width of 24 mm, and a 24 mm width embossed carrier tape having a pocket size of 12 mm X 15 mm X 5.5 mm is molded by an EDG carrier tape molding machine. Obtained.
- a skin layer resin is poly mosquitoes Bone preparative resin Panra wells L one 1 2 2 5 (Teijin Chemicals Ltd.) and force one Bonbura Tsu a click Ketchenbura click EC (Lion AKZO Co.) 1 2 Weight 0 / 0 was previously kneaded and pelletized with a 50 mm bent type twin screw extruder to obtain a conductive resin compound.
- Sheets and embossed carrier tapes were obtained in the same manner as in Example 1 except that polyethylene terephthalate resin (abbreviated as PET in Table 1) was used.
- PET polyethylene terephthalate resin
- Polystyrene resin (abbreviated as FS in Table 1) is used as the skin layer resin.
- a three-layer sheet having a thickness of 400 m and a conductive resin composition layer of 30 m on both sides was obtained.
- an embossed carrier tape was obtained in the same manner as in Example 2.
- Example 5 Example 5
- styrene-methyl methacrylate copolymer resin (abbreviated as MS in Table 1)
- MS styrene-methyl methacrylate copolymer resin
- Comparative Example 1 in which a sheet of 0 m and embossed carrier tape were obtained.
- a conductive resin compound obtained by kneading and pelletizing was obtained.
- a sheet and an embossed carrier tape were obtained in the same manner as in Example 1 except that the compound was used.
- a sheet and embossed carrier tape having a thickness of 500 m were obtained in the same manner as in Example 5 except that styrene-methyl methacrylate copolymer resin TP-SX (Electrochemical Industry Co., Ltd.) was used.
- TP-SX Electrochemical Industry Co., Ltd.
- a sheet and an embossed carrier tape were obtained in the same manner as in Example 4 except that the polystyrene resin Torostyrene HRM20 (Toyo Styrene Co.) was used as the base layer resin.
- Torostyrene HRM20 Torostyrene Co.
- a sheet and an embossed carrier tape were obtained in the same manner as in Example 2 except that a polystyrene resin, toluene, polystyrene HRM20 (Toyo Styrene Co., Ltd.) was used as the base layer resin.
- the obtained sheet tear strength was measured in accordance with JIS K7-128-3, and the embossed carrier tape was subjected to a heat graph tensile test to set the gap between the chucks to 32 mm.
- Table 1 shows the evaluation results of the tensile test performed at a tensile speed of 10 cm / min.
- a carrier tape strength of 60 N or more was obtained, but in the comparative examples, the strength was less than 50 N.
- a mounting test for an embossed 100-pocket was performed using a mounting machine of 0.1 sec. In the example, no trouble occurred in which the embossed carrier tape was broken, but in each comparative example, a trouble occurred in which the embossed carrier tape was broken. table 1
- a sheet for embossed carrier tape having a tear strength according to JIS-K-7128-8-3 of 10 SN / mm or more can be suitably used for high-speed mounting.
