Problems solved by technology
Such an anisotropic conductive material tape is sometimes wound and stacked in a reel shape and provided as a reel product. However, as the amount of the anisotropic conductive material tape used increases, the time until reel replacement is shortened, which may cause problems in terms of production efficiency.
In addition, there are cases where winding collapse occurs when the narrow-width anisotropic conductive material tape is made into a reel shape.

Embodiment 1）
[0045] (1) Fabrication of a laminate of a substrate film and an anisotropic conductive material layer
[0046] Add 50 g of phenoxy resin (high molecular weight epoxy resin) as a film-forming material, 20 g of epoxy resin, and 5 g of imidazole to prepare a 30% by weight solution of ethyl acetate, and add 5% by volume of Ni powder with an average particle diameter of 2.5 μm . Use a thin and blue colored transparent polyethylene terephthalate film with a thickness of 50 μm (breaking strength 25 kg / mm 2 , elongation at break 130%) is a substrate film with silicone treatment on both sides. The solution was applied to one side of the substrate film using a roll coater, and dried at 110° C. for 5 minutes to obtain a laminate of the substrate film and the anisotropic conductive material layer with a thickness of 50 μm.

Abstract
The present invention provides an adhesive material laminating body and a winding body thereof. In particular, the present invention provides an adhesive material laminating body having an adhesive material layer between a first base material film and a second base material film which are opposite, wherein the first base material film and / or the second base material film have adhesive layers on surfaces which are opposite to the surfaces facing to the adhesive material layer. The adhesive material laminating body of the present invention can prevent scatter of winding even if being wound on a winding core to form a winding body, in addition, replacements in the production can not be performed frequently, and performance stability of the adhered product can be improved.
Description
technical field [0001] The present invention relates to an adhesive material laminate and a wound body thereof. Background technique [0002] There is known an anisotropic conductive material tape which can achieve conduction between electrodes and bonding of substrates by sandwiching between opposing electrodes and applying heat and pressure. Such anisotropic conductive material tapes are sometimes wound and stacked in a reel shape and provided as a reel product. However, as the amount of anisotropic conductive material tape used increases, the time until reel replacement is shortened, which may cause problems in terms of production efficiency. In addition, winding collapse may occur when a narrow-width anisotropic conductive material tape is made into a reel shape. [0003] Therefore, in order to prolong the interval between the replacement time of the reel and prevent the decrease in workability caused by the collapse of the winding, an anisotropic conductive material ta...
