PURPOSE:To prevent a conductive adhesive from protruding and to surely connect an electronic component to a board by a method wherein the electronic component is connected to the board by using a frame, for protrusion-preventing, which dams up the conductive adhesive. CONSTITUTION:An anisotropic conductive film 3 is sandwiched between an electronic component 1 and a board 11; a bonding tool 7 is lowered; the electronic component 1 is pressed to the board 11 by using the bonding tool 7; the electronic component 1 and the anisotropic conductive film 3 are heated; the anisotropic conductive film 3 is compressed. A resin adhesive 4 as the anisotropic conductive film 3 is spread a little to the outside; it comes into contact with a frame 12 and dammed up. In addition, the resin adhesive 4 is hardened; the electronic component 1 is connected to the board 11 in a state that an electric current can be applied. Thereby, the resin adhesive 4 which is compressed and spread can be dammed up by using the frame 12; it is possible to eliminate that the resin adhesive 4 becomes insufficient; the electronic component 1 can be connected to the board 11 wholly and surely. |
