Wire Break Z Offset
This option is used when ball or stud bumping. The tool is moved to the top of the ball bond and then
takes a step backwards to terminate the wire at the top of the ball.
The number entered controls the elevation of the tool before the Y motor takes a step back to terminate
or wipe the wire off the top of the ball bond.

Ultrasonic Positioning Utility (UPU)
In past years, tool height has been determined by design. To effect this end, tool height gauges have
been supplied with wire bonding machines, allowing the user to set the tool height at the designed bond
point. However, we have found that the designed tool height does not always allow the most efficient
transfer of ultrasonic energy from transducer to tool. This is due largely to the fact that no two bonding
tools are exactly alike. W
EST•BOND has developed the UPU to obtain this optimum transfer of ultrasonic
energy with every tool. Granted, each tool will continue to be different and will therefore require different
setup variables. The UPU just provides the best way to setup and transfer the maximum amount of
ultrasonic energy to each tool.
The UPU consists of a specially designed circuit to provide a measure for placement of each tool. This
raw data is crunched by a software routine which then displays a relative number on the machine’s LCD.
When adjusting the tool height, the goal is to obtain the highest possible numerical value for each tool
installed. As all tools are different, this value will be slightly different for each bonding tool.
