Adhesive tape structure and adhesive tape container

Abstract

The present invention provides a technique allowing a tremendous extension in length to be achieved for an adhesive tape without having to modify an existing base support or adhesive coating mechanism. The present invention is an adhesive tape structure (1) comprising a plurality of adhesive tapes (2) linked through linker tapes (3). A predetermined interval is provided between an extremity of an adhesive tape (2) and an extremity of a linker tape (3). In this state, an extremity of a base film (20) of the adhesive tape (2) and an extremity of a linker substrate (30) of the linker tape (3) are adhered together by a substrate-side adhesive member (41). At the same time, so that a release cover film (22) of the adhesive tape (2) and a release film (32) of the linker tape (3) can be released as one strip in the length direction of the tape, an extremity of the release cover film (22) and an extremity of the release film (32) are adhered together by a release-side adhesive member (42). The type of base resin for a pressure-sensitive adhesive layer (45A) of the substrate-side adhesive member (41) and the type of base resin for a pressure-sensitive adhesive layer (46B) of the release-side adhesive member (42) are different.

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

[0142] Using the above-mentioned adhesive tape and connecting tape, a Figure 5 (a) Sample of the adhesive tape structure of the structure shown.

[0143] In this case, as the substrate-side adhesive member, a silicon-based adhesive tape (Dexerials Co., Ltd. Society) system T4082S).

[0144] On the other hand, as the peeling side adhesive member, an adhesive made of acrylic resin (SK Dyne 1717 manufactured by Soken Chemical Co., Ltd.) with a thickness of 40 μm formed on a PET base material with a thickness of 38 μm was used. A silicon-based adhesive tape with a layer length of 5 cm.

[0145] Then, two adhesive tapes having a length of 50 m were bonded with the connecting tape having a length of 30 cm using the adhesive member on the substrate side and the adhesive member on the peeling side to prepare a sample of an adhesive tape structure.

Embodiment 2

[0147] A sample of an adhesive tape structure was produced under the same conditions as in Example 1 except that the thickness of the adhesive layer of the peeling-side adhesive member was 10 μm. it is Figure 6 structure shown.

Embodiment 3

[0149] A sample of an adhesive tape structure was produced under the same conditions as in Example 1 except that the thickness of the adhesive layer of the peeling-side adhesive member was 20 μm. it is Figure 6 structure shown.
