Note: If the contacting edges of panels are complicated as shown below, the pitch must be up to the

center of the overlapping edges. In this case, a part of the panels appears to extend beyond the

pitch range, but this will not cause a problem.

In “Rotated Multi-Panel PCB” given earlier in this manual, offset values are entered to create

repeat data for PCBs consisting of panels rotated at different angles. Please note that, with this

multi-panel PCB generation function, the panel pitch must be entered.

2-7-6-5 Head Substitution

Menu: Program>DataEditUtilities>HeadSubstitution

This function automatically generates a program that uses an alternative head in cases where a

particular head is no longer usable due to breakdown.

Note: When the data is saved after head substitution is performed, the original data will be lost. So, it is

recommended that the original data be saved in another name and then head substitution be

performed on that data.

Note: Executing the head substitution function will not alter feeder arrangement. In addition, the

number of nozzles used will not be increased.

Head, needs to be skipped

Specify a non-usable head. It is not possible to specify two or more

heads at the same time. If you want to specify two or more heads,

disable all the non-usable heads first in the system parameters, and

then execute the head substitution function for each of non-usable

heads repeatedly.

Note: To cancel them, select System > System Parameter > Parameter > Head/ANC Setup from the main

menu.

Substitute Placement The placement steps for which heads selected in “Head, needs to be

skipped” are designated will be deleted from the corresponding cycle

and assigned to another cycle. Here, select the priority condition to be

given when creating an alternative step instead of the deleted step.

(Priority to Multiple Pickup (Postpone) / Priority to Placement Order

(Next Cycle))

Note : In either case, if non-used heads having the same nozzle are

present within the same cycle, the program will be modified so that

substitute placement is performed using those heads.

● Priority to Multiple Pickup (Postpone)

The deleted placement steps are assigned collectively at the

end of the program. Multiple pickup is performed as much as

possible to reduce the placement tact time. Some restrictions

will apply to the postpone processing. Refer to [NOTE].

● Priority to Placement Order (Next Cycle)

If a head that uses the same nozzle as that of the non-usable

head is designated in the same cycle, the deleted placement

steps are inserted before the next cycle. This enables placement

with the placement order specified in the program taken into

account. However, if there is no head with the same nozzle in

the cycle, the deleted placement steps will be postponed to the

end of the program (multiple pickup). Some restrictions will

apply to the postpone processing. Refer to [NOTE].

Note: Postpone processing for substitute placement are restricted in the following cases.

① If two or more pairs of non-grouped fiducial marks are present, postpone processing will be

performed within the effective range of those fiducial marks.

② If two or more non-grouped bad marks are present, postpone processing will be performed

within the effective range of those bad marks.

③ In the case of repeat data, postpone processing will be performed within the repeat range.

④ If the program handles components exceeding 10.5mm in height, postpone processing will

not be performed in any cases, and the deleted placement steps are inserted before the next

cycle. In this case, if there is no head using the same nozzle, nozzle change will be performed.

2-7-6-6 Reduce the number of nozzle for use

Menu: Program>DataEditUtilities＞Reduce_the_number_of_nozzle_for_use

For a program with multiple-pickup process by several heads, this function converts the program

so that it needs less number of nozzles. This is convenient when you cannot prepare the necessary

amount of nozzle.

Note: This function cannot be used if a data check error is present.

Items:

Nozzle ID: Select a Nozzle ID to reduce the number for use.

The number for use: Current amount of nozzle for use is shown on the left, and specify the

reduced number on the right.

Example:

1) The original program has multiple-pickup process by Head 1 to 8 using ID-32 nozzles. 8 pieces

of ID-32 nozzle should be prepared for this program.
