Device for pressure bonding an integrated circuit to a printed circuit board

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 first 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 first columnar member overlapped on the IC pressurizing member so as to bring an external surface of the first columnar member into contact within the IC pressurizing member groove;
• an intermediate member having first and second surfaces opposing each other, the first surface having a first intermediate member groove formed thereon and extending in the first direction, the second surface having a second intermediate member groove formed thereon and extending in a second direction perpendicular to the first direction, the intermediate member being overlapped on the first columnar member so as to bring an external surface of the first columnar member into contact within the intermediate member first groove;
• a first adjusting member for adjusting parallelism between the IC pressurizing member and the intermediate member;
• a first fixing member for fixing a relative position between the IC pressurizing member and the intermediate member;
• a second columnar member overlapped on the intermediate member so as to bring an external surface of the second columnar member into contact within the intermediate member second groove;
• a pressure receiving member having a pressure receiving member groove extending in the second direction and overlapped on the second columnar member so as to bring the external surface of the second columnar member into contact within the pressure receiving member groove;
• a second adjusting member for adjusting parallelism between the intermediate member and the pressure receiving member;
• and
• a second fixing member for fixing a relative position between the intermediate member and the pressure receiving member.

A pressure device for pressure bonding an IC chip on a circuit board and having a plurality of pressure mechanisms arranged close to each other, each of the pressure mechanisms comprising:

• an IC pressurizing member having an IC pressurizing member groove extending in a first direction, the IC pressurizing member being formed on a surface of the IC pressurizing member opposite to a surface of the IC pressurizing member abutting the IC chip;
• a first columnar member overlapped on the IC pressurizing member so as to bring an external surface of the first columnar member into contact within the IC pressurizing member groove;
• an intermediate member having first and second surfaces opposing each other, the first surface having a first intermediate member groove formed thereon and extending in the first direction, the second surface having a second intermediate member groove formed thereon and extending in a second direction perpendicular to the first direction, the intermediate member being overlapped on the first columnar member so as to bring an external surface of the first columnar member into contact within the first intermediate member groove;
• a first adjusting member for adjusting parallelism between the IC pressurizing member and the intermediate member;
• a first fixing member for fixing a relative position between the IC pressurizing member and the intermediate member;
• a second columnar member overlapped on the intermediate member so as to bring an external surface of the second columnar member into contact within the second intermediate member groove;
• a pressure receiving member having a pressure receiving member groove extending in the second direction and overlapped on the second columnar member so as to bring the external surface of the second columnar member into contact within the pressure receiving member groove;
• a second adjusting member for adjusting parallelism between the intermediate member and the pressure receiving member;
• and
• a second fixing member for fixing a relative position between the intermediate member and the pressure receiving member.
