A. The effective range for the master bad mark ① is until immediately before master bad mark ⑬.
The master bad mark ① determines whether the bad mark process ②/④ will be performed or
not.
B. When the placement ⑧ is to be determined by the group bad mark ② regardless of the result of
the master bad mark ① process, “254” shall be entered in the [B Group No.] cell.
C. The group bad mark ② determines whether the placement ⑧ will be performed or not.
D. The standard bad mark ④ determines whether the placement of the following each block will
be performed or not.
E. The effective range for the master bad mark ⑬ is until the end of the placement program.
The master bad mark ⑬ determines whether the bad mark process ⑭/⑯ will be performed or
not.
F. The standard bad mark ⑭ determines whether the placement of all the blocks after the step ⑮
will be performed or not.
G. The standard bad mark ⑯ determines whether the placement of the following block will be
performed or not.
Example Program for Multi-block PCB
An example of a multi-block PCB aiming to reduce cycle rate is shown below.
[Conditions]
1. The master bad mark A is used to determine whether the following bad mark processes will be
performed or not.
2. IC1 and IC2 shall be picked up continuously (multiple pickup process) to reduce cycle rate.

2-7-1-4 Repeat Programs and Bad Marks

Program>Placement&MarkData>Task>RepeatOffset
In producing multi-up panels, the same program is repeated for the number of boards. This
section describes programming of repeat programs and bad marks.
Example1:Four-board panel:
40mm
40mm
60mm
60mm
DC
B
A
Suppose the program for board A is as follows:
X Y
10.00 10.00
30.00 20.00
To repeat the above program for the remaining boards (B ⎝ C ⎝ D), the program will be as follows:
X Y Task Board
0.00 0.00 Start Block Placement
10.00 10.00 Multiple Pickup A
30.00 20.00 End Multiple Pickup A
0.00 0.00 End Block Placement
60.00 0.00 Repeat Offset B
60.00 40.00 Repeat Offset C
0.00 40.00 Repeat Offset D
Note: Offset values in a repeat offset step are always based on the original board position for which the
repeat program is created. (board A in the above example)
Note: Only the Task setting is required for the Start Block Placement/End Block Placement steps.
Effective Range for a Bad Mark Inspection
z Assign a bad mark step immediately before a repeat block
The result of the bad mark inspection is effective up to the end of the repeat block. When the bad
mark is present, the entire repeat block will be skipped.
Note: To assign a bad mark step, specify a bad mark code to [Code] of the step.
z Within a repeat block, assign only one bad mark step immediately after [Start Block Placement]
step
The result of the bad mark inspection is effective up to [End Block Placement] step. This
assignment is typically used for skipping a particular board of a multi-up panel.
