Patent ID: 7025852

Claim:
A mounting method, comprising: applying a connecting material comprising a thermosetting resin, a latent curing agent, and a surfactant onto a wiring circuit board on which a bare IC chip is to be mounted, positioning the bare IC chip on the wiring circuit board, and applying heat and pressure to connect the bare IC chip to the wiring circuit board; wherein the connecting material is manufactured by a process comprising: uniformly mixing together the thermosetting resin and the latent curing agent to form a resin composition; and uniformly mixing 0.01 to 5.0 parts by weight of a surfactant with 100 parts by weight of the resin composition so as to allow the connecting material to have a surface tension at 25° C. of 25 to 40 mN/m and a viscosity at 25° C. of 10,000 to 500,000 mPa·s.
