A controller may receive a wire disconnection signal from a wire bonding
monitoring system and operate a wire clamp to clamp a disconnected wire.
A series of operations, which may include a wire drawing operation, a
wire tail forming operation and a ball forming operation, may be
automatically performed. A sensor may measure the length of the wire
drawn through the capillary and the location of a ball that may be formed
at a wire tail. An auxiliary clamp may be installed between the wire
clamp and the capillary for drawing the wire using sensor information.
