Abstract
An apparatus and method of supporting lead fingers during a wire bonding process and method of preventing the bonding apparatus and clamping assembly from applying force against the die. The present invention includes the use of a movable arm with a portion that is positionable under a portion of the lead fingers of a lead frame during the wire bonding process to provide increased stability of the lead fingers and prevent the bonding apparatus and clamping assembly from applying force against the die. The present invention also provides for the transfer of heat from the heat block directly to the lead fingers during the wire bonding process. The present invention includes the use of a clamp for stabilizing lead fingers during the wire bonding process.
Claims10
Apparatus for supporting at least one lead frame element for a wire bonding process comprising:
- at least one support for positioning below said at least one lead frame element for said wire bonding process, a surface of said at least one support for contacting a bearing surface and for moving on a portion thereof, said at least one support including a portion for positioning at a location between lead fingers and a semiconductor device, the portion of said at least one support contacting a lower surface of said lead fingers located above the semiconductor device without providing support therefor;
- and
- a heating apparatus for heating said at least one support.
