•
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
first L-axis descending movement.
