Patent ID: 6978534

Claim:
A pressure device for pressure bonding an IC chip on a circuit board of the pressure device comprising: an IC pressurizing member having an IC pressurizing member groove extending in a predetermined direction, the IC pressurizing member groove being formed on a surface of the IC pressurizing member opposite to a surface of the IC pressurizing member abutting the IC chip; a columnar member overlapped on the IC pressurizing member so as to bring an external surface of the columnar member into contact within the IC pressurizing member groove; a pressure receiving member having a pressure receiving member groove extending in a predetermined direction and overlapped on the columnar member so as to bring the external surface of the columnar member into contact within the pressure receiving member groove; an adjusting member for adjusting parallelism between the IC pressurizing member and the pressure receiving member; and a fixing member for fixing a relative position between the IC pressurizing member and the pressure receiving member.
