(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.
Undetected Ball

(B02_06) Lighting pattern
Set a lighting pattern to be used for component recognition.
Fig. 20
(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.

(3) Front ltg 1 (Ring (Dn))
When "Manual" is selected in the "Lighting pattern" text box, select
one of the following options ("On" or "Off") as the lighting pattern for
the lower ring lamp for the front lighting system.
(4) Front ltg 2 (Coax)
When "Manual" is selected in the "Lighting pattern" text box, select
one of the following options ("On" or "Off") as the lighting pattern for
the coaxial lamp for the front lighting system.
(5) Fron ltg 3 (Ring (Up))
When "Manual" is selected in the "Lighting pattern" text box, select
one of the following options ("On" or "Off") as the lighting pattern for
the upper ring lamp for the front lighting system.
(B02_07) Image capture method
Select one of the following options as a method to capture an image of
the picked component.
Disable : A proper method is automatically selected.
Single : The image of the component is
captured at the camera center position.
When the image is captured, the height
position of the nozzle end is regarded as an
element of no importance.
Single (Descent) : When an image is captured, the height
position of the nozzle end is kept at a
position lower than the underside of the
linear measure sensor.
This method should be taken for the area
array components, etc., that might be
interfered by the lighting linear measure
sensor.
To set a parameter, select "Manual" in the "Recog data set" text box.
