6.2 Component Library
The component library data must be edited for the components that can be
handled by the flux dispensing unit.
When the "Control Data" tab is pressed in the "Component Library" edit
window, the corresponding tab sheet appears inside the window.

[1] Control Mode
"Placement (Normal)" or "Dipping Placement" can be selected from the
"Control Mode" combo box.
Placement (Normal) :
When this option is selected, the machine
performs normal processing of component
placement.
Dipping Placement :
When this option is selected, the components
are dipped in flux.

Operation mode settings.
Outward Recog. : Ball + Outline → Flux application → Outline
Bump Recog. : Ball → Flux application → Ball
•
Outward Recog. mode
In the case that the bump can not be recognized after the flux
application, then this mode is used.
Perform the bump recognition and outline recognition before the flux
application, and again perform the outline recognition after the flux
application.
Based on the position relationship resultant from the outline recognition
before and after the flux application, calculate the bump position and
perform placement.

Bump Recognition mode
In the case that the bump can be recognized even after the flux
application, then this mode is used.
Perform the bump recognition in each of "2. Component Recognition
(Bump, Outline)" and "4. Component Recognition (Outline)" steps.

Descent dclr [%]
Enter a deceleration rate for the second L-axis descending stroke.
The figure below shows the L-axis control system related to the drum
surface on which flux is dispensed.
Note
"Placement Descent 1 [%]" is applied as a deceleration rate of the
