3.4.11 Retry
The Retry drop-down list specifies the tuning behavior of the Config during the retry
sequence at runtime. The retry order for Configs is specified in the Options tab (see
Section 3.5).
SELECTION DESCRIPTION
Disable (default)
The Config will be tried, but not fine tuned*; fine tuning differs from the more exhaustive tuning
process during setup (see Section 3.4.15).
Enable The Config will be tried, and fine tuned.
Enable & Apply
The Config will be tried and can be fine tuned. If tuned successfully the new settings will be
applied to the Config, overwriting the previous settings.
*Fine tuning adjusts the Light Power by ± .5 ms, in increments of .2 ms. It also adjusts the Size region ± 1 pixel, both high and wide.
This continues on all enabled Configs until the there is either a read or the timeout is exhausted.
NOTES
■ Enabled must be checked for a Config to be included in the retry sequence, regardless of the Retry
selection.
■ The Retry setting is ignored when the In-Sight protocol TUNE(<Config>) command is issued.
3.4.12 Color
The Color setting is optional in most Configs, for use when the optimal Light Mode for a
particular type of wafer mark is already known, or when the Bright Field and Dark Field
checkboxes will be disabled during tuning.
By default In-Sight will automatically determine the correct color of the mark as imaged
during the tuning process if both the Bright Field and Dark Field checkboxes in the Tune
dialog are enabled.
SELECTION DESCRIPTION
Auto (default) Automatically selects ‘White’ or ‘Black’ depending on the current Light Mode setting.
Black Specifies a black mark on a light background. Use when Light Mode is set to Bright Field.
White Specifies a light mark on a dark background. Use when Light Mode is set to Dark Field.
NOTE The Color setting is ignored when the selected Mark is a barcode.
3.4.13 Region
The Region defines the area in which the wafer mark is expected to appear in the FOV.
The mark must be sufficiently illuminated and entirely contained within the Region or the
read will fail. Generally, the mark may be rotated as much as ± 5 degrees within the
region without a significant decrease in readability.
NOTE When '2D Sym, T7 Data Matrix' is the selected Mark, the Region must be set no larger than 120
pixels high. If the Region height is set larger than 120 pixels, the read will fail.
