39. Wire Clamp
There is no convenient way to measure the clamp force. The user must therefore be alert to deformation of the
wire to identify excess force. When force is inadequate, the wire clamps will not hold the wire in the tool during
closed clamp conditions or will not break the wire after second bond.
Clamp force adjustment
Clamp gap adjustment
Clamp position
the wire should be straight between clamp and wedge tool.
Clamp problems:
Clamp is not open.
- open set screw for gap adjustment and increase the gap size.
- check clamp connector
Clamp is not closing
- check clamp force, increase clamp force
- open set screw for gap adjustment and increase the gap size
To clean wire clamp increase gap to 2mm, use alcohol or acetone to soak a clean paper,
put this paper in clamp gap, close clamp and pull the paper down, repeat that 5 times.
