This process updates the value of Chuck to NCH/Button Delta under

Saw > Dicer > Cutting Blocks in Setup and Diagnostics screen.

7.4.3 Blade Dressing

Blade Dressing is performed in order to prepare a Blade for use. Blade

Dressing has three main purposes:

• Expose the new diamonds

• Shape the blade

• Reduce runout

There are three methods of Dressing a Blade:

• Using a Dressing Workpiece (wafer or block) mounted on the Cutting

Chuck

• Performing Override cutting on the same substrate under process

• Using the Dress Station that enables the user to perform Blade

dressing as part of the dicing process (For more details about this

option, refer to

section 9.3.)

When the Dressing algorithm has been selected in a Recipe and a Blade is

changed, the System automatically performs Dressing according to the

method specified in the After Change Treatment parameter (Blade

category). If the After Change Treatment parameter is set to None, no

automatic Dressing is performed, but the User can perform manual

Dressing if required.

7.4.3.1 Comparison Between Dressing with a Dressing Workpiece and

Override

The two major differences between dressing with a Dressing Workpiece

and Override are:

• Dressing is performed on a specially designated workpiece, whereas

Override is performed on a production workpiece

• Only one speed can be defined for the entire length of the cut in

Override. That speed is less than the speed used for a normal cut.

Table 7-1 describes in detail the differences between the two methods.

Note: It is recommended to perform a Chuck to Non-Chuck Delta

Measurement procedure only with a blade that has been dressed or worked

with.
