3.1 Board parameters

Selecting the [Board] tab opens the screen that allows you to set or check the following

board parameters.

A, B: Board Size XY

Enter the length of the PCB in the XY directions in millimeters. The conveyor width (W-axis) will

be adjusted according to the Y length in automatic operation.

C: Board Size Height

Enter the thickness of the PCB in millimeters.

D: Board Comment

You can enter a comment for the PCB as necessary.

E: Prod. Board Counter

Enter the number of PCBs already produced. Set this value to "0" as a start.

F: Prod. Board Count Max.

Enter the number of PCBs that you want to produce. When this is set to "0", the machine continues

to produce PCBs as long as they are fed on the conveyor.

G: Prod. Block Counter

Enter the number of blocks on one PCB when producing multi-block PCBs.

H: Unloader Counter

Specify the number of PCBs transferred into the unloader. Set this value to "0" as a start.

Creating the PCB data

3. Creating the PCB information

I: Unloader Count Max.

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. If this is set to "0", the machine

continues production without checking the number of PCBs transferred out into the unloader. Enter

"0" in the following cases.

• The unloader being used provides a rack switching signal output.

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

J: Board Fix Device

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

"Edge Clamp" :

PCB is clamped on the conveyor with the edge clamps, push-in unit and push-up pins, without

using the locate pins.

"Locate Pin" (option) :

PCB is clamped on the conveyor only with the locate pins.

"Pin+PushUP" (option) :

PCB is clamped on the conveyor with the locate pins and push-up pins. This is the most accurate

and recommended method.

K: Pre Fix Timer sec

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.).

L: 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.

M: Conveyor Timer sec

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.

N: Alignment

Set to "UseAlign" to check the image of a component by vision recognition during component

pickup.

O: Vacuum Check

Set to "Check" to check whether a component is being picked up, by detecting the vacuum level, as

well as checking with the vision system.

P: Retry Sequence

The retry sequence when a pickup or recognition error occurs 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.

Q: Precede Pick

Set to "NotUse" in most cases. When 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.

V: Conveyor X Speed

This parameter specifies the conveyor X-axis speed. If components move or slide just after

mounted on the PCB due to the X-axis movement, set this parameter to a lower speed.

X: Conveyor Motor Speed (%)

Set the conveyor motor speed (PCB transfer speed). With respect to the machine setting speed, the

conveyor speed can be adjusted to 50% on the plus side and 90% on the minus side in 10% steps.
