Operation 6-23
6.9.4 Workpiece Alignment
Prior to creating your dispensing program, you should setup workpiece alignment and define the number
of fiducials to be used in your program. Workpiece alignment refers to the position of the board or part in
relation to the Dispensing Head X- and Y-axes. Even if the board is slightly askew, FmXP can use
workpiece alignment to adjust the patterns and dispense correctly. Once you have established workpiece
alignment parameters, workpiece alignment will be performed at the beginning of each production run
and at the beginning of each new board in the run. Checking for workpiece alignment can be eliminated if
speed is a factor. In that case, correct workpiece alignment and symmetry are assumed.
To Setup Workpiece Alignment:
1. Select
Setup Workpiece Alignment from the Configuration menu and make sure there is a
checkmark in the box next
to Workpiece Angle first. See Figure 6-18.
! If you select
Learn Workpiece Angle first, you will be prompted to define the
workpiece orientation in the X- or Y-axis when you begin programming.
! FmXP compares the defined axis to the dispensing head axis to adjust for workpiece
alignment.
" NOTE If Setup Workpiece Alignment is not activated, you will be asked if you want to Learn
Workpiece Angle first?
each time you begin a new programming session. However, to
ensure workpiece alignment, it is a good idea to activate this feature in the Configuration
Menu.
