| 20090107625 | Anisotropic Conductive Film - An anisotropic conductive film is provided which can provide high bonding strength and good conduction reliability when anisotropic conductive bonding is made under the compression bonding conditions of a compression bonding temperature of at most 130° C. for a compression bonding time of at most 3 seconds. The anisotropic conductive film contains a polymerizable acrylic compound, a film-forming rein, conductive particles, and a polymerization initiator. The polymerization initiator contains two types of organic peroxides that do not produce oxygen gas resulting from the decomposition thereof and have different one-minute half-life temperatures. Of the two types of organic peroxides, one organic peroxide that has a higher one-minute half-life temperature produces benzoic acid or a derivative thereof when it decomposes. | 04-30-2009 |
| 20090178834 | ANISOTROPIC ELECTRICALLY CONDUCTIVE FILM AND CONNECTION STRUCTURE - An anisotropic electrically conductive film formed by a thermosetting acrylic resin composition is disclosed. The composition contains at least a thermosetting agent (A), a thermo-settable ingredient (B), an acrylic rubber containing hydroxyl groups (C), organic fine particles (D) and electrically conductive particles (E). The thermo-settable ingredient (B) may include a phosphorus-containing acrylic ester (b1). The weight averaged molecular weight of the acrylic rubber containing the hydroxyl groups (C) is not less than 1000000. The organic fine particles (D) include polybutadiene-based fine particles (d1). | 07-16-2009 |
| 20090280332 | Adhesive composition - An adhesive composition is provided which is capable of providing good adhesion strength to the polyimide surface of a flexible circuit board that is exposed on the metal wiring surface and between the traces even when the polyimide surface is relatively smooth. The adhesive composition contains a thermoplastic resin, a polyfunctional acrylate, and a radical polymerization initiator and further contains a monofunctional urethane acrylate having a urethane residue at its terminal end. The monofunctional urethane acrylate is represented by the formula (1): | 11-12-2009 |

The conductive particle includes a base particle ( | 03-04-2010 |
| 20110095235 | CONDUCTIVE PARTICLE, ANISOTROPIC CONDUCTIVE INTERCONNECTION MATERIAL THAT USES THE CONDUCTIVE PARTICLE, AND METHOD FOR PRODUCING THE CONDUCTIVE PARTICLE - There is disclosed a conductive particle used for an anisotropic conductive connection material for establishing conductive interconnection between e.g. a substrate and an electrical component. The conductive particle includes a base particle ( | 04-28-2011 |
| 20110110066 | ANISOTROPIC CONDUCTIVE FILM - A high adhesive strength and good conduction reliability can be realized when anisotropic connection is performed under compression conditions of a compression temperature of 130° C. and a compression time of 3 seconds using an anisotropic conductive film which uses a polymerizable acrylic compound capable of being cured at a comparatively lower temperature and in a comparatively shorter time than a thermosetting epoxy resin along with a film-forming resin. Consequently, an anisotropic conductive film has a structure in which an insulating adhesive layer and an anisotropic conductive adhesive layer are laminated. The insulating adhesive layer and the anisotropic conductive adhesive layer each contain a polymerizable acrylic compound, a film-forming resin, and a polymerization initiator. The polymerization initiator contains two kinds of organic peroxide having different one minute half-life temperatures. Of the two kinds of organic peroxide, the organic peroxide having the higher one minute half-life temperature produces benzoic acid or a derivative thereof by decomposition. | 05-12-2011 |
