Abstract

The purpose of the present invention is to provide a feature which makes it possible to achieve significant lengthening of adhesive tape without having to add modifications to already-existing original cloth or adhesive coating mechanisms. The present invention is an adhesive tape structure (1) wherein a plurality of adhesive tapes (2) in which an adhesive layer (21) and a peel cover film (22) have been provided sequentially upon a base film (20) are joined via a joining tape (3) in which a pressure-sensitive adhesive layer (31) and a peel film (32) have been provided sequentially upon a joining base material (30). An end section of the base film (20) of the adhesive tape (2) and an end section of the joining base material (30) of the joining tape (3) are adhered together by a base material-side adhesive member (41), and an end section of the peel cover film (22) of the adhesive tape (2) and an end section of the peel film (32) of the joining tape (3) are adhered together by a peel-side adhesive member (42), so that the peel cover film (22) and the peel film (32) are peeled integrally.

Description

technical field

[0001] The present invention relates to a technique for increasing the size of an adhesive tape for solar cell tab wire bonding or the like. Background technique

[0002] Conventionally, long-sized adhesive tapes for bonding various electronic components and the like are known.

[0003] Such an adhesive tape is formed on a narrow and long release sheet, and is shipped in the form of a roll wound on a reel.

[0004] In addition, at the manufacturing site, the adhesive tape is pulled out from the reel for use, and when the adhesive tape is used up, the production line is temporarily stopped and the adhesive tape is replaced with the reel.

[0005] However, if the length of the adhesive tape is short, it is necessary to stop the production line every time the reel is replaced, which reduces the production efficiency.

[0006] Therefore, in recent years, so-called "lengthening" which makes the length of the adhesive tape which can be wound up on one reel as lon...

Examples

Embodiment 1

[0105] An adhesive layer and a peeling film were sequentially formed on a connection substrate made of black PET with a thickness of 50 μm to produce a connection tape.

[0106] The pressure-sensitive adhesive layer is composed of the following resin A.

[0107] That is, the composition of the resin A contains 100 parts by weight of a silicon-based resin (SD4584PSA manufactured by Toray Dow Corning Co., Ltd.), 0.7 parts by weight of a curing agent (BY24-741 manufactured by Toray Dow Corning Co., Ltd.), and a silane coupling agent. (A-187 manufactured by Momentive Performance Materials Co., Ltd.) 1 part by weight, platinum catalyst (NC-25 manufactured by Toray Dow Corning Corporation) 0.6 parts by weight.

[0108] This composition was applied to the joint base material with a rod coater, heated at 70°C for 5 minutes, and then heated at 150°C for 4 minutes to harden it to form an adhesive layer with a thickness of 20 μm.

[0109] In addition, as the release film, a release film...

Embodiment 2

[0111] As a material of the pressure-sensitive adhesive layer, a connection tape was produced on the same conditions as in Example 1 except that a material composed of the following resin B was used.

[0112] Here, the composition of resin B includes 30 parts by weight of phenoxy resin (YP-50 manufactured by Nippon Steel Chemical Co., Ltd.), 20 parts by weight of liquid epoxy resin (JER828 manufactured by Mitsubishi Chemical Corporation), and rubber component (Nagase Chemtech Co., Ltd. 10 parts by weight of SG80H manufactured by Co., Ltd., 40 parts by weight of hardener (Nobakyua 3941HP manufactured by Asahi Kasei Co., Ltd.), and 1 part by weight of silane coupling agent (A-187 manufactured by Momentive Performance Materials Co., Ltd.).

Embodiment 3

[0114] A connecting tape was produced under the same conditions as in Example 1, except that 5% by weight of a fused silica filler (FB-5D manufactured by Denka Corporation) was added to the above-mentioned resin A.
