Creating and setting the data

C: Board Size Height (mm)

Enter the board thickness (mm).

D: Board Comment

Enter a comment on the board. You can leave this field blank.

E: Solder Name

Enter the name or comment on the solder to be used. You can leave this field blank.

F: Board Datum Position

Set the reference position on a board select by selecting from "Center", "Front Center", "Rear Center", "Front Left", "Front

Right, "Rear Left" or "Rear Right" as shown below. On standard machines, this is set to "Front Left" as the default. All

coordinate positions on a board are specified relative to the "Board Datum Position" coordinates.

TIP

The board has "Origin XY", "Fiducial (Mark)" and "Board Check Position" parameters as its setting positions .

G, H: Origin X, Y (mm)

If the fiducial mark on a board uses an origin different from the Board Datum Position, set the positional offset (mm) here

as the Origin XY.

I: Spin Timer (sec)

Set to "1" second for normal shape boards. If specially configured boards (for example, boards with cutouts or through-

holes) are used and the conveyor exit sensor cannot detect them correctly, try setting this timer between 0.0 and 9.9

seconds. The conveyor motor continues turning for the specified time even after the board sensor turns off.

Board parameters (2)

64411-L3-10

J: Board Vacuum

This parameter is enabled only for machines equipped with an optional vacuum gripper. Set to "NotUse" in most cases.

When curved boards or thin boards are to be printed, setting this parameter to "Use" actuates the vacuum gripper to fix

the board from the backside. When this parameter is set to "Use", also specify an appropriate time (msec) in the "Vacuum

Timer" and "Board Vacuum Sequence" parameters.

K: Vacuum Timer (msec)

When the "Board Vacuum" parameter is set to "Use", set the timer (msec) here to initiate the next action after the push-up

plate has moved up. This parameter is enabled only for machines equipped with an optional vacuum gripper.

L: Board Vacuum Sequence

This parameter is enabled only when the "Board Vacuum" parameter is set to "Use". Set to "Before Clamp" to turn on the

vacuum gripper before clamping a board. Set to "After Clamp" to turn on the vacuum gripper after clamping a board.

M: Edge clamp

The edge clamps secure the board in the printing position by laterally pushing on the board edge. Set this parameter to

"Use" in most cases. If printing on boards which cannot be clamped from the edge such as thin ceramic boards, set to

"NotUse" and use a vacuum board gripper instead.

N: Edge Clamp Pressure

Set an edge clamp pressure level (0.05 to 0.225MPa) that is optimal for the board. This pressure is set to 0.225MPa as the

default.

If multi-block boards or thin boards warp upwards when force is applied by the edge clamp, reduce the edge clamp air

pressure. Conversely, increase the air pressure if you want to clamp heavy boards more securely.

NOTE

When data (edge clamp pressure: 0.4MPa) set by the YGP (earlier model) is loaded, it is automatically be converted

to 0.225MPa in the YSP.

O: Board flap

Set whether to use the board flap that presses on the board edge from above.

Usually, set this parameter to "Use". Using the board flap corrects the upward warp of a board that might occur when

clamped.

Q: Board Press (option)

The board press unit holds down the board surface to correct the overall warp. Set this parameter to "Use" when using

the board press unit (option) or to "NotUse" when not using that unit. (This parameter is available only for machines

equipped with an optional board press unit.)

R: Press Timer (msec)

When an optional board press unit is used, set the length of time to press on a board.

S: Board Press Sequence

When an optional board press unit is used, set whether to start pressing on a board before or after the edge clamp is

actuated.

T: Push Up Speed (%)

Specify the ascent/descent speeds for the push-up plate in percentage. Setting to "100" is acceptable in most cases, but

reduce it if you want to lessen the impact when the push-up jigs or pins move up against the board.

U: Print Execution

Select the operation mode from "Exec" or "Skip".

Exec : The machine performs solder printing.

Skip : The machine operates without applying any force.

Creating and setting the data

V: Alignment

Select the processing method after fiducial mark recognition. Set to "UseAlign" in normal operation, and the machine

immediately stops when a mark recognition error occurs. When this is set to "IgnoreErr", the machine continues operation

even if a mark recognition error occurs.

W: Print Feedback

Always set this parameter to "Use" when producing boards. (If you want to check the squeegee head movement without

controlling the printing pressure, set this parameter to "NotUse".

X: Board Distortion Tol.

This parameter specifies the allowable distortion limit when checking the distortion component in the board fiducial

recognition position and local fiducial mark recognition positions on the board. The distortion check is not performed

when this parameter is set to "0.00".

If the distortion component calculated by recognizing the board fiducial marks or local fiducial marks during automatic

operation exceeds the allowable limit specified here, an error message box appears as shown below and the machine

stops. After closing the error message box, you can select whether to print solder on the board or to convey the board

out without printing solder according to the dialog box that appears.

Y: Air conditioner interlock

When an optional temperature control unit is used, set whether or not to enable the interlock mechanism that functions

if an abnormal temperature is detected.
