Abstract
A wire feed system for a wire bonding apparatus is provided. The wire feed system includes a spool for storage of a wire, a wire tensioner, and a wire guide adapted to form the wire into a predetermined configuration between the spool and the wire tensioner. The wire tensioner and the wire guide are supported such that relative movement between the wire tensioner and the wire guide during a wire bonding procedure is substantially prevented.
Claims25
A wire feed system for a wire bonding apparatus:
- a spool for storage of a wire;
- a wire tensioner;
- and
- a wire guide adapted to form the wire into a predetermined configuration between the spool and the wire tensioner,
- the wire tensioner and the wire guide supported such that relative movement between the wire tensioner and the wire guide during a wire bonding procedure is substantially prevented.
A bond head for a wire bonding machine, the bond head comprising:
- a spool for storage of wire;
- and
- a first moveable support structure configured for moving at least a portion of the bond head along a first axis, the portion of the bond head including the spool.
A wire bonding apparatus comprising:
- a bond head including a capillary adapted to receive a wire, the bond head movably supported for translation in an X-Y working plane during a wire bonding procedure;
- a wire tensioner for tensioning the wire received by the capillary as the capillary moves in the X-Y plane;
- and
- a wire guide adapted to form the wire into a predetermined configuration, the wire guide and the wire tensioner being supported with the bond head for movement with respect to the X-Y working plane so as to substantially inhibit relative movement between the wire guide and the wire tensioner during a wire bonding procedure.
A wire feed system for a wire bonding machine comprising:
- a slack loop device including an airflow mechanism adapted to direct a flow of air against a bonding wire received from a wire supply so as to form the wire into a slack loop configuration;
- and
- a wire tensioner adapted to receive the bonding wire from the slack loop device and apply tension to the bonding wire,
- the wire tensioner and the slack loop device supported such that relative movement between the wire tensioner and the slack loop device during a wire bonding procedure is substantially inhibited.
