Patent ID: 8071425

Claim:
A flip chip mounting method for disposing a semiconductor chip having a plurality of electrode terminals so as oppose a circuit board having a plurality of connection terminals and connecting the connection terminal of the circuit board and the electrode terminal of the semiconductor chip electrically, the flip chip mounting method comprising: deforming a porous sheet so as to have a box shape covering the semiconductor chip; adhering the semiconductor chip to an inside bottom part of the porous sheet having a box shape; applying a solder resin composition that contains solder particles, a convection additive and a resin as main components onto the circuit board or the semiconductor chip; positioning so as to dispose the porous sheet on the circuit board; heating the resin composition to a temperature at which the solder particles are melted so as to generate gas by boiling or decomposition of the convection additive; and connecting the connection terminal and the electrode terminal electrically by allowing the melted solder particles to flow in the resin composition so as to self-assemble and grow the solder particles before the gas is released, passes through the porous sheet and is scattered.
