Backbend
This particular feature is an excellent aid in creating good loop shape when using a 454647E in the
4600E and 4700E modes. The position of the clamps on the 4500E mode allow greater control of the wire
requiring less finesse when it comes to loop motion. B
ACKBEND occurs immediately after the motor has
counted up the specified number of Z-B
EFORE-Y steps. An excessive amount of BACKBEND can easily peel
the first bond from the work. However, if used properly, B
ACKBENDING can add not only shape, but also
height to your wire loops. To achieve truly effective BACKBENDS, the operator needs to strike a balance
between the number of Z-B
EFORE-Y steps versus the number of BACKBEND steps.

Loop Elevation
The highest point the tool reaches in the looping procedure. It is important to remember that this
maximum tool height does not equate to loop height. As the tool begins it descent toward the work
surface, this high point of the wire will be pulled down with the tool. Wire loop height is dependant upon
many factors other than just L
OOP ELEVATION (contributing factors: Z-BEFORE-Y, BACKBEND, Y-OFFSET,
LOOP ELEVATION, NUDGE-UP, wire size, wire strength, wire material, bonding tool, clamp position, etc.).
