Abstract:
A circuit connection method, in which a protuberant electrode of an electronic component is connected to a terminal electrode of a circuit board for carrying said electronic component through an adhesive material containing at least one curable resin and inorganic particles, said circuit connection method being characterized in that an adhesive material in which inorganic particles whose specific surface area S (m2/g), as determined by the BET method, satisfies Equation (1) below and whose mean particle size D1 (&mgr;m) and maximum particle size D2 (&mgr;m) respectively satisfy Equations (2) and (3) below3&lE;17â€ƒâ€ƒ(1) D1>5â€ƒâ€ƒ(2) D2 >0.5(h1+h2)â€ƒâ€ƒ(3) (wherein h1 represents the height of the protuberant electrode in the electronic component, and h2 represents the height of the terminal electrode in the circuit board) are dispersed in a curable resin in an amount of 10 to 60 vol %, is used as the adhesive material.
