2) Packaging style
From the displayed "Packaging style" list, select a component supply device.
To change it, select a packaging style from the pull-down list.

Tray
3) Outer dimensions
Enter outer dimensions of component matched to each component type.
Enter them by referring to the component illustration shown in the lower left part of the form
screen. Note that there are 2 cases, namely, one where the lead is included and the other
where the lead is not included, depending on the component type.
The graphic data based on JUKI component feed angle definition 0° is displayed according
to "Component type."
Example: W = Outer dimension, horizontal
L = Outer dimension, vertical H: Component height
♦ Square chip ♦SOT ♦T-SOP
♦ Socket ♦BGA
If you enter the dimensions oppositely, that is, enter the width (horizontal) to the
“Length” field or vice versa, the system may not be able to center the component.
If a wrong component height is entered, a laser recognition error may be easily
caused by unstable laser measuring position.
4) Other
① Pick depth
Enter the height from the nozzle pick surface to the top surface of the component. Usually,
the default value is used for operation.
② Boss Height
Enter the boss height (projection height on the bottom surface) of the connector.
Usually, the default value is used for operation.
Component height＝Component height measured with laser－Boss height
If the picking surface of the nozzle is located at the lower position than the top surface of the
component, such as connector component, enter the distance from the nozzle tip to the top
surface of the component. In this case, the "Component height" will be the distance from
the nozzle tip to the bottom surface of the component.

Example:
5) Centering method
Specify the method of obtaining the center of the component.
Select this method according to the component (in consideration of specifications, accuracy,
and tact). However, available centering methods are limited depending on the component
type.

6) Package size
If the size of a portion on which the laser beam strikes of a component such as a boss LED
lens component is different from that of the package part (body) when the component is
recognized, enter the package size (PW/PL) here.
7) <OK> button and <Cancel> button
When you press the <OK> button, the system validates your editing and quits the “Form”
screen.
When you press the <Cancel> button, the system discards your editing and quits the “Form”
screen.
When you quit the “Form” screen, the system redisplays the “Placement” data screen if you
invoke the “Form” screen from the “Placement” screen, or the “Component” data list screen
if you invoke the “Form” screen from the “Component” data list screen.
If you quit the “Form” screen with any method other than buttons (by the menu command or
by selecting a tab), the system executes the same process as when you press the <OK>
button.
