When it is failed, execute the following procedures. If the parts are not defined with any
existing algorithms, please use the Smart Recognition function.
(a) When a whole parts body is not within the view, make [Body Size X] and [Body Size
Y] larger.
(b) When the view is out of focus, change the value of [Body Size Z].
(c) Select alignment type by hand, and create body size automatically. (Refer to 3.2)
3.2 Auto creation of Body Size without changing Alignment Type
To create only body size and lead data without changing alignment type, execute auto
creation of body size through the following procedure.
(1) Parts basic data
On the [Parts] screen, select parts data and enter the following information.
[Basic] tab ・・・ [Required Nozzle], [Package], [Feeder Type] etc.
[Pick] tab ・・・ [Feeder Set No.] etc.
[Shape] tab ・・・ [Body Size X], [Body Size Y], [Body Size Z]
* [Body Size X] and [Body Size Y] are used to roughly decide the camera area, so that they
don’t need to be exact values.
* The first image is applied with Light Main=ON, Light Coax=ON (When “Alignment Type”
is “Simple BGA” or “BGA”, Light Side=ON), and Lighting Level=7/8. Therefore, you
don’t need to make lighting settings for that.
(2) Pick up
Press the [PartsAdj] button to open the [Parts Adjust] screen. Specify a head number and
press the [Pick Up] button, so that the head picks up the parts.
(3) Execution of “Measurement size”
Set [Parts Find Best Target] to “Size,Light”, and press the [Find Best] button. [Body Size]
is automatically defined based on the parts image, and parameters of [Lighting Level] and
[Comp. Threshold] are tuned.
(4) Completion
When it is successfully completed, “Vision parameters optimized” is displayed in the result
area. [Body Size] after [Find Best] is displayed on the grid above. (Change of Body Size is
not displayed in the result area.） Also, [Monitor Mode] is automatically switched to
“Defined Shape”, and a parts recognition image and a defined shape are overlaid on the

vision window.
If it is failed, execute the following procedures. If the parts are not defined with any
existing algorithms, please use the Smart Recognition function.
(a) When a whole parts body is not within the view, make [Body Size X] and [Body Size
Y] larger.
(b) When the view is out of focus, change the value of [Body Size Z].
(c) Set alignment type to be a target of auto creation. (Refer to 3.1)

also when a value is set on [3D Co-Planarity Threshold].
(*3) Supported only for “Sp. Chip”, “Melf Chip”.
< Remarks >
* If auto-created parts size is too large to be recognized by the side view camera, [Parts] -
[Side View] - [Side View Camera] is automatically set to “Not Use”.
* Even when auto-created alignment type is not supported for co-planarity check, the
setting of [Parts] - [Vision] - [3D Co-Planarity Threshold] is not changed.
4.2 Alignment Type automatically created
Below is alignment types that may be created when [Parts Find Best Target] is set to
“Type,Size,Light”, and that can execute “Size,Light”. (If unsupported alignment type is
selected, items of “Size,Light” are not displayed in the [Parts Find Best Target] combo
box.)
