Patent ID: 7951700

Claim:
A flip chip packaging method for connecting a first electronic component including a plurality of connecting terminals and a second electronic component including a plurality of electrode terminals corresponding to the connecting terminals, comprising the steps of: mounting a solder resin composition including a solder powder and a resin on the first electronic component; arranging the connecting terminals of the first electronic component and the electrode terminals of the second electronic component to face each other; wherein the first electronic component is in a state to eject a gas when heated; ejecting a gas from a gas generation source included in the first electronic component by heating the first electronic component and the solder resin composition; and inducing the flow of the solder powder in the solder resin composition by inducing convection of the gas in the solder resin composition, and electrically connecting the connecting terminals and the electrode terminals by self-assembly on the connecting terminals and the electrode terminals.
