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.

Abstract

The present invention discloses an anisotropic conductive film. The anisotropic conductive film comprises preset amount of color composite inorganic pigment (CICP). The CICP causes easy confirmation for existence of the anisotropic conductive film after the film is pre-compressed on a circuit component without electric performance deterioration or thermal performance deterioration of the film.

Description

technical field [0001] The present invention relates to an anisotropic conductive film. More particularly, the present invention relates to an anisotropic conductive film comprising a colored composite inorganic pigment (CICP) which makes it easy to confirm the properties of the anisotropic conductive film after pre-pressing the film to a circuit element such as a PCB. exist without degrading the electrical and thermal properties of the film. Background technique [0002] The anisotropic conductive film refers to a film-like adhesive in which conductive particles such as metal particles or metal-coated plastic particles are dispersed. Anisotropic conductive films are widely used in various fields including circuit connection in the field of flat panel displays and component assembly in semiconductor devices. When the anisotropic conductive film is inserted between the circuits to be connected, followed by hot pressing under suitable temperature, pressure and time condition...
