Problems solved by technology

However, in order to connect two carrier tapes without hindering the detachability of the cover tape, it is necessary to precisely adjust the bonding position, and it is difficult to mechanize, so manual work has been done by humans.
In addition, in order to quickly attach to the exact position, considerable proficiency is required, and the working efficiency largely depends on the proficiency of the operator, so it is difficult to obtain a fixed working efficiency
Furthermore, if the adhesive tape is processed by adding dotted and linear cracks or the like in order to facilitate alignment, the work efficiency will be somewhat improved, but the production cost of the adhesive tape will increase, and the adhesive tape will become expensive, which will become a problem

Embodiment 1

[0123] Use a mixing roller to masticate the natural rubber (cryllium rubber) to obtain a masticated rubber with a Mooney viscosity ML1+4 (100°C) of 70. 100 parts of the obtained masticated rubber, 50 parts of terpene resin (trade name "YS Resin PX1150", manufactured by YASUHARA CHEMICAL Co., Ltd.) were uniformly dissolved in 400 parts of toluene to obtain a binder (1).

[0124] The obtained adhesive (1) was coated on a 25 μm uniaxially stretched PP film (trade name “MCMD-AS”, manufactured by FUTAMURA CHEMICAL CO., LTD.) so that the thickness after drying was 25 μm, and the Adhesive tape (1).

[0125] From the obtained adhesive tape (1), cut out the first direction with the main stretching direction of the base material as the plane, the second direction with the main stretching direction of the base material as the plane, and the plane with the main stretching direction as the second direction. The side parallel to the first direction (side (first direction)) is the long side...

Embodiment 2

[0130] 100 parts by weight of an acrylic copolymer with butyl acrylate / acrylic acid (weight ratio: 100 parts by weight / 3 parts by weight) as constituent monomers, 5 parts by weight of an isocyanate-based crosslinking agent (trade name "CORONATE L", NIPPON POLYURETHANE Industry Co., Ltd.) was diluted with ethyl acetate until the non-volatile content was 30% by weight to obtain a binder (2).

[0131]An adhesive tape ( 2 ) was produced in the same manner as in Example 1 except that the adhesive ( 2 ) was used instead of the adhesive ( 1 ).

[0132] The adhesive tape (2) for carrier tape connection (2) and the film (2) for carrier tape connection were obtained in the same manner as in Example 1 except that the adhesive tape (2) obtained in Example 2 was used instead of the adhesive tape (1). .

Abstract

The invention relates to an adhesive tape, a carrier tape connecting thin film, a carrier tape connecting method and a connected carrier tape. The invention relates to an adhesive tape which is characterized in that a face of a substrate is provided with an adhesive layer. Tear-resisting strength in a first direction of the face and tear-resisting strength in the second direction which is perpendicular to the first direction are characterized in that when the tear-resisting strength in the second direction is 1, the tear-resisting strength in the first direction is less than 0.75.

Description

technical field [0001] The present invention relates to an adhesive tape for connecting an end portion of a carrier tape for supplying electronic components to an electronic component mounting machine with an end portion of another carrier tape, a film for connecting a carrier tape including the adhesive tape, and a film using the same The connection method of the carrier tape and the connection of the carrier tape. Background technique [0002] Small electronic components mounted on printed circuit boards by electronic component mounting machines are conveyed, stored, and supplied mainly by carrier tape or embossed carrier tape, which is formed by punching holes in a paper base material, in the holes obtained The embossed carrier tape is formed by placing the above-mentioned small electronic components and attaching the bottom tape and the cover tape to both surfaces of the base material. The embossed carrier tape is formed by forming depressions on the base material such a...
