3 Height Measurements, section 7.3

4 Blade Handling, section 7.4

5 Chuck Change, section 7.5

7.1 Z-Axis Safety

To ensure the Z-Axis safety, the System defines the Z Height Movement,

which is the lowest point that Z-Axis can travel while the X and Y Axes are

in motion. The Z Height Movement is the minimum of three values which

are all parameters in the Setup and Diagnostics workbook. These

parameters are entitled Z-Axis Safety Position, Z-Axis Return Height,

Calibration Start Position, and Pre Non Contact Height.

7.1.1 Z-Axis Safety Position

The Z-Axis Safety Position is an area on the Z-Axis set with reference to

the Workpiece used and its tape thickness. It is automatically calculated by

the following formula: [Chuck position - Substrate thickness - tape

thickness - Safe parameter].This parameter can be viewed in Setup and

Diagnostics > Dicer > Axes > Z > Axis Z Safety Position. If this value

is lower (from the top) than Calibration Safety Position or Pre Non Contact

Height, it is used for the Z Height Movement.

7.1.2 Z-Axis Return Height

The Z-Axis Return Height is the height at which the blade should move

above the workpiece while returning from the end of the finished cut to the

beginning of the next one.

This parameter can be viewed in Setup and Diagnostics > Dicer > Axes

> Z > Z-Axis Return Height. Its value should not be lower (from the top)

than the Z-Axis Safety Position.

7.1.3 Calibration Start Position

Calibration Start Position is the parameter which determines the safety

area above the Chuck that can be used for the Z Height Movement. This

parameter is set by the User.
