Part 1
• STN 1: Parts Pickup
Parts are picked from the feeder tape.
• STN 2: Large Parts Pickup Check
This station inspects large parts.
• STN 3: Pθ (Pre Theta)
Picked parts are checked to confirm that their theta orientation
is roughly where it should be, and rough corrections are made,
as follows:
Parts Orientation Corrective Rotation Angle
0˚ ~ 45˚ 0˚
45˚ ~ 180˚ 90˚
180˚ ~ 315˚ -90˚
315˚ ~ 0˚ 0˚
Further adjustments are made at station 6.
• STN 4: Inspection
The part is inspected and the corrections are computed.
• STN 5: No Function
• STN 6: Fθ (Fine Theta)
Using the calculations derived from the image in station four,
in conjunction with the coordinates obtained from reading the
fiducial marks on the board, final adjustments are made in
positioning the part.
• STN 7: Parts Placement
Using the previously obtained coordinate data, the part is
placed on the board.
• STN 8: No Function
• STN 9: Nozzle Check
The nozzle position in the Z axis is checked to ensure that the
nozzle has returned to its raised position.
• STN 10: Reject Parts Dump and Nozzle Position Check
Parts deemed by the vision system as defective or outside
dimensional tolerances are dumped at this station into the
reject box. The nozzle which was used is checked here also.

Part 1
• STN 11: Nozzle Change
A nozzle that is compatible for picking the next part is selected
and the nozzle change operation is carried out accordingly.
• STN 12: Nozzle Change Check
A check is carried out to confirm that the appropriate nozzle
has been selected.
If a nozzle change alarm has occurred then the head that has
caused the alarm will stop here.
6.2.5 Parts of the Board Loader System
The FCP IV-3 has three conveyor systems to transport boards and a
table to hold the board during production. These conveyors are
called the in conveyor, the main conveyor and the out conveyor. It
is possible to have one board on each conveyor. Although the
board usually moves from left to right as shown, it is also possible
for the board to move the other way. In this case, the names of the
conveyors remain the same, as do their loading capacities.

6.3 Changing the Original Table
The original device table (that is, the table which is used first) is selected
automatically when a new production program or table mode is selected.
The conditions under which the original table will change are listed
below.
6.3.1 Change Due to Change of Production Program
The original table is determined according to the table mode when
the new production program is selected, as follows:
• Changeover mode (1A 2B)
The original table changes depending on the setting in
Original_table in Machine data, as explained below.
Machine_data
37. Original_table (Non, Table1, Table2)
Non :The table other than the table used until now is
the original table. If table 1 had been used, table 2
will be the original table, and vice versa.
Table1 :When the program has been changed and
foreground transmission has been carried out
table 1 will be the original table.
Table2 :When the program has been changed and
foreground transmission has been carried out
table 2 will be the original table.
When Original_table is specified and many programs have
used the same devices, then parts must be replaced and the
original table specified manually.
• Device Change Mode (1A 2A)
The table other than the table used until now is the original
table. If table 1 had been used, table 2 will be the original table,
and vice versa.
• Joint Mode (JOINT)
There is no original table.
