Creating and setting the data

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.

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.

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.

Creating and setting the data

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) (option)

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

Board parameters (2)

64511-N1-00

S: Board Press Sequence (option)

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.

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.

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 screen that appears.

Y: Air conditioner interlock (option)

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.

m: Trans Height (mm)

After components are mounted, the machine permits the conveyor to carry out the board when the push-up unit is

lowered. If components have already been mounted on the reverse side of the board, 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 board. Enter a numeric value ranging from 0 to

50 mm showing how many millimeters the transfer height is lowered from the height of the bottom surface mounted

component or board warpage.

When this parameter is set at "0 mm", the transfer height lowers to the maximum down height.

o: Conveyor Motor Speed (%)

Change this parameter setting if you want to change the conveyor motor speed (board transport speed). The conveyor

motor speed can be increased up to "Standard+50%" (150% of "Standard" speed) or decreased down to "Standard-90%"

(10% of "Standard" speed) in 10% steps.

p: Carried Pos. Check

Enables/disables the conveyance position check. The standard setting is "Enable". When enabled, the board's position is

verified by the board vision camera which checks the board's 1st fiducial mark before the conveyed board is secured.

q: Carried Pos. Check Value (mm)

Enter a value that is used to judge whether or not the board position is corrected when checking the transfer position.

A value ranging from 0.0 to 5.0 mm can be entered.

If the mark position is beyond the set range, the board is moved by the mark shift amount.

(This parameter is enabled

only if the "o: Carried Pos. Check" item is set as "Enabled".)

r: Carried Pos. Detail Setting

Make this setting when a mark different from the fiducial mark or first point is used to check the transfer position. The

standard setting is "Disabled". (This parameter is enabled only if the "o: Carried Pos. Check" item is set as "Enabled".)

s: Carried Pos. Check Mark

Inputs the mark No. used for the conveyance position check detailed setting. The input value setting range is 0 to 128.

The recognition status of the mark used for the conveyance position check must be verified by performing a mark position

check, and the mark must then be registered in the mark information. (This parameter is enabled only if the "r: Carried

Pos. Detail Setting" item is set as "Enabled".)

t: Carried Pos. Check Mark X (mm)

Inputs the X-coordinate of the conveyance position check mark. (This parameter is enabled only if the "r: Carried Pos.

Detail Setting" item is set as "Enabled".)

u: Carried Pos. Check Mark Y (mm)

Inputs the Y-coordinate of the conveyance position check mark. (This parameter is enabled only if the "r: Carried Pos.

Detail Setting" item is set as "Enabled".)

v: Board Edge Offset Lower Left, w: Board Edge Offset Lower Right

If the board edge cannot be detected by the board detection sensor due to board shape, press the [Offset Teach] button to

enter a distance from the board edge to the sensor detection position through teaching. The initial value is "0.0". When

the board edge offset function is not used, remain the initial value. (For details about teaching, see "3.2.2 Board edge

offset" in Chapter 3.)
