Abstract: Preparation methods of an anisotropic conductive adhesive film are provided. One of the preparation methods includes heating a solid-state light-curing resin, a solid-state thermosetting resin and a solid-state elastomer to form a mixture. A liquid-state light curing active monomer and plasticizer are added to the mixture. A leveling agent, antioxidant and insulating nanoparticles are added separately to the mixture. Conductive particles are added to the mixture. A light curing agent, latent heat curing agent and coupling agent are added to the mixture to produce a light-beat dual curing anisotropic conductive adhesive. The conductive adhesive is coated on a plastic film base material to form a semi-finished product. The semi-finished product is cured and dried to form a cured conductive adhesive layer, so that an anisotropic conductive adhesive film is produced. The anisotropic conductive adhesive layer is cut, and the anisotropic conductive adhesive film is rolled.

Abstract: An autorotation and revolution magnetic stirring device for producing conductive golden particles comprises a mounting holder, a rotary electric motor, a flask, a magnetic stirrer, and a magnetic rotor. The rotary electric motor is fixed to the mounting holder. The flask is rotatably mounted to the mounting holder. The rotary electric motor provides rotary power to make the flask rotate. The magnetic rotor is put into the flask. The magnetic rotor rotates due to the magnetic force from the magnetic stirrer. In the present invention, the solvents in the flask rotate due to the rotary of the flask and the rotary of the magnetic rotor. “Revolution” and “autorotation” exist at the same time, so the solvents are stirred more adequately and more evenly so as to obtain an excellent surface treatment effect.
