4.2.6 (B02) Recognition Data
(B02_01) Lighting system
"Front Ltg System" is selected as a lighting system for component
recognition.
(B02_02) Recognition data set
Select one of the following options to specify whether the recognition data
related to each individual component shapes should be set automatically or
manually.
Auto : The defaults (determined in advance) are automatically set.
Manual : Each recognition data can be set manually.
(a) Select "Auto" in normal cases.
(b) When "Auto" is specified in the "Recognition data set" text box,
each parameter is automatically set as follows.
The specified parameters in the table (the parameters specified when
"Auto" is selected) are defined individually in this manual (each data
item).

(B02_04) Recognition level
Set a recognition level for component checking.
Set "0" in normal cases.
• Data Input Range
00 to 99
(a) When "1" or a larger number is set, "Manual" should be selected in
the "Recog data set" text box.
(b) The following shows the contents of Recognition Level 1 or higher.

(B02_05) Front ltg recog algo
Specify a recognition mode.
Grid Pattern:
When "BGA/CSP (Simple)" is selected, this recognition mode can be
specified.
The electrodes consisting of meshes (grids), the bumps, etc., can be
detected.
Multi Pattern:
When "BGA/CSP (Complex)" is selected, this recognition mode can be
specified.
The electrodes, bumps, etc., arranged at random can be detected.
To set a parameter, select "Manual" in the "Recog data set" text box.
Note
Positioning is performed,
using only the detected
balls.
(No Ball Detection)
Positioning is possible even
when some of the balls
cannot be detected due to
deformations, etc.

(B02_06) Lighting pattern
Set a lighting pattern to be used for component recognition.

(1) Ltg pattern designation
Select one of the following options to designate a lighting pattern.
Auto : The lighting patterns are automatically set for all lighting
units.
Manual : The lighting patterns (On/Off patterns) can be set
individually for each lighting unit.
(a) When the recognition cannot be made correctly due to improper
lighting condition, set proper lighting patterns for the selected
component.
(b) To set a parameter, select "Manual" in the "Recog data set" text box.
(2) Back ltg
When "Manual" is selected in the "Lighting pattern" text box, select
one of the following options ("On" or "Off") as the lighting pattern for
back lighting recognition.
