Embodiment 1
[0071] Example 1: Preparation of anisotropic conductive film
[0072] 30g solution (25vol%) of acrylonitrile butadiene rubber (weight average molecular weight=30000000g / mol) in toluene / methyl ethyl ketone (2:1 (v / v)), 15g bisphenol A type epoxy Resin, 33g of bisphenol A type epoxy acrylate resin, 5g of phosphoethyl (meth)acrylate, 1g of lauroyl peroxide, 1g of benzoyl peroxide, 8g of nickel with an average particle size (D50) of 5 μm The particles were blended with 1 g of copper-chromium oxide (Black 30C965, Shepherd) to prepare an anisotropic conductive film composition. This composition was coated on a polyethylene terephthalate film as a release film, and dried to prepare an anisotropic conductive film having a coating thickness of 35 μm.
Embodiment 2~7
[0073] Examples 2-7: Production of anisotropic conductive film
[0074] An anisotropic conductive film was produced in the same manner as in Example 1, except that the content and / or type of each component was changed as shown in Table 2.
