Wire bonding apparatus

A wire bonding apparatus, comprising:

• a loading portion configured to hold a substrate;
• a capillary on the loading portion and configured to draw out a conductive wire onto the substrate;
• a wire supply portion configured to supply the conductive wire to the capillary;
• and
• a wire holder between the capillary and the wire supply portion, the wire holder having a first clamp and a second clamp that are spaced apart from each other and are configured to clamp the conductive wire,
• wherein the first clamp includes a plurality of first contact surfaces and is configured to rotate about a first central extension line passing through a center of the first clamp, and
• wherein the second clamp includes a plurality of second contact surfaces spaced from the plurality of first contact surfaces and is configured to rotate about a second central extension line passing through a center of the second clamp.

A wire bonding apparatus, comprising:

• a loading portion configured to fix a substrate;
• a heater below the loading portion and configured to heat the substrate;
• a capillary on the loading portion and configured to draw out a conductive wire onto the substrate;
• a wire supply portion including a spool configured to supply the conductive wire and a plurality of guides configured to transfer the conductive wire from the spool to the capillary;
• and
• a wire holder between the capillary and the wire supply portion and configured to hold the conductive wire,
• wherein the wire holder includes a first clamp having a plurality of first contact surfaces and a second clamp having a plurality of second contact surfaces,
• wherein the first clamp and the second clamp are spaced apart from each other and are configured to clamp the conductive wire, and
• wherein each of the first and second clamps includes,
• a support body configured to rotate about a central axis of the support body;
• and
• a rotation shaft configured to protrude from one end portion of the support body along the central axis of the support body, the rotation shaft being integral with the support body and configured to rotate with the support body about the central axis the support body.
