PCB Finishing Position
The PCB Finishing Position is selected in this text box.
Output
The component placement is performed on the downstream side.
Note
The PCB nishing position should be xed on the downstream side.

PCB Top [mm]
When some components are placed previously on a PCB by the input
machine, etc., and transferred to the main machine, be sure to enter the
thickness of the tallest component of all in the text box.

Notice
(a) When components are placed previously and the main machine
is operated with "0.00" (no previously placed components) in
this text box, some of the previously placed components may
interfere with components to be placed newly.
(b) It is advisable that placement data should be created such that
shorter components are placed before the tallest one.
