Creating the PCB data

q Specify “Unloader Count/Max”.

In the Y/Y1 column of this parameter, specify the number of PCBs that can

be stored in one rack of the unloader. When the specified number of PCBs

has been produced and transferred out into the unloader, the machine

stops transfer of the production PCB until the unloader replaces the rack.

• Unloader Count

The number of PCBs transferred into the unloader is displayed in this

column. Set this to “0” as a start.

• Max

Specify the maximum number of PCBs that can be stored in one rack

of the unloader. If this is set to “0”, the machine continues production

without checking the number of PCBs transferred out into the

unloader. Enter “0” under the following conditions.

The unloader being used provides a rack switching signal output.

This setting data is to be used for the machine just before

reflowing.

w Set operating conditions.

Using the [Space], [INS] or [DEL] key, specify the necessary operating

conditions displayed on the lower half of the screen,

• Mount

Set to “Exec” to perform component mounting.

• VacCheck

Set this parameter to “Use”. Setting to “Use” allows the machine to

check whether components are being picked up during operation

based on the vacuum level, as well as checking with the vision

system.

• Alignment

Set to “UseAlign”. This setting allows the machine to check compo-

nent recognition during pickup.

• PcbFixDevice

Select the proper PCB clamping method according to the PCB to be

produced.

Locate Pin : A PCB is clamped on the conveyor only with the

locate pins.

Pin+PushUP : A PCB is clamped on the conveyor with the

locate pins and push-up pins. This is the most

accurate and preferred method.

Edge Clamp (option) : A PCB is clamped on the conveyor with

the edge clamps, push-in unit and push-up

pins, without using the locate pins.

• Pre-Fix Timer

The machine begins to clamp the PCB immediately after it passes

above the PCB sensor installed just before the main stopper. The

optimum clamping timing (delay time with respect to the sensor

detection) depends on the PCB size and conveyor speed.. Use this

parameter to set the clamp timing (0.0 to 1.9 sec.).

Creating the PCB data

• Trans-Height

After components are mounted, the machine permits the conveyor to

carry out the PCB when the push-up unit is lowered. If components

have already been mounted on the reverse side of the PCB, the push-

up unit must be lowered sufficiently to avoid interference from push-

up pins with those components. This parameter specifies the height of

the push-up unit at which the conveyor is allowed to carry out each

type of PCB. Enter the distance in millimeters from the point where

the push-up unit is raised to clamp the PCB. This distance can be 3 to

30mm.

• Conv. Timer

Set to “0.0” sec. for normal shape PCBs. If specially configured PCBs

(for example, PCBs with cutout parts or through-holes) are used and

the exit sensor cannot detect them reliably, try setting this timer in the

range of 0.0 to 9.9 sec. The conveyor motor continues turning for the

specified time even after the PCB sensor turns off.

• Precede Pick

When this is set to “Use”, the head assembly starts moving to pick up

and recognize components as soon as the preceding PCB has been

carried out and the next PCB is carried in. This will shorten the cycle

time.

• Conv. Y Speed

This parameter specifies the conveyor Y-axis (YT-axis) moving speed.

Set to “FAST” in most cases. If the mounted components move or

slide on the PCB due to the YT-axis movement, set this parameter to a

slower speed.

• Local Fiduc.

Set to “Use” when using the local fiducial correcting function, and

“NotUse” when not using this function. This parameter is available

only when the data is input in “Fidu. Info.” in the main window

menu. Refer to “5. Using the fiducial functions” in Chapter 6 for more

details.

• Local Badmark

Set to “Use” when using the local badmark function, and “NotUse”

when not using this function. This parameter is available only when

the data is input in “Local BadMrkInfo.” in the main window menu.

Refer to “6. Using the badmark functions” in Chapter 6 for more

details.

• Retry Seq.

The retry sequence can be selected from the following methods.

“Group” : Retry is repeated with the head which caused an error,

until component mounting specified as one group is

complete.

“Block” : Retry is performed with the head which caused an error

after component mounting in one block is complete.

“Auto” : Retry is performed with any free head after component

mounting in one block is complete.

• Sp. Function

This parameter is not displayed on standard machines. If the machine

has a special function, set to “Use” when using it, or “NotUse” when

not using.
