3. Details of each parameter item
To continuously perform the production with excellent printing quality, it is absolutely required to properly set
conditions for each solder paste printer as described previously.
The following describes how the conditions for each operation affect the printing quality.
Each parameter item
3.3 Mark position 3.4 Alignment offset
3.5 Rolling
3.7 Detach pattern
3.8.1
Cleaning interval
3.6 Solder supply interval

3.1 Board clamp
3.1.1 Edge clamp pressure
n
Function
This parameter sets a level of the air pressure supplied to the cylinder which is used to catch a board and clamp it.
n
Setting range and initial value
This parameter can be set in a range of 0.001 to 0.225MPa.
The initial value is 0.225MPa.
n
Setting procedures
Adjust the edge clamp pressure with the regulator so that the board does not move or deform.
3.1.2 Backup jig
n
Function
This jig supports a board from the bottom when it is clamped.
n
Setting procedures
There are three kinds of backup jigs as described below.
• Matrix pin : Used with the push-up pins inserted into the matrix plate. (Printing of B-surface of double
sided mounted board, etc.)
• Flat surface backup : Used with the blocks (support jigs) placed on the matrix plate. (Mounted board with one
flat side)
• Vacuum gripper backup : Used for boards having a height of 0.5 mm or less. (This backup is set on the [Board] tab
screen.)
n
NOTE
Matrix pins and flat surface backup can be used together to support a board.

3.2 Board transfer
The YCP10 adapts a "servo transfer" that does not use the main stopper.
Unlike the transfer using the main stopper, since the positioning of the board stop position is performed by the
sensor response and servomotor RPM, the board stop position may vary depending on the transfer speed, board
material, surface treatment, shape, or weight.
In particular, when using bottom surface mounting boards, the board push-up may occur by the push-up
material during board clamp.
Therefore, functions to make the positioning of the board stop position stable are enhanced. Furthermore, in
addition to the functions to make the positioning stable, functions to make the transfer tact faster are also
provided. Make the settings appropriately according to the board.
c
CAUTION
Before starting the production, check the transfer sufficiently to make sure that any board push-up or drop does not
occur.

3.2.1 Transfer position check
n
Function
This function recognizes a desired mark by the board vision camera to correct the deviation amount of the transfer
position before board clamp.
This function increases the positioning accuracy of the board clamp.
n
Setting procedure
On the [Print]-[Board] tab screen, set "p. Carried Pos. Check" to "Enable" and set the values for related parameters.
(For details about how to set each parameter, see "3.1 Board marks and parameter setting" in Chapter 5.)

3.2.2 Board edge offset
n
Function
This function sets a deviation in response position of the board detection sensor when detecting the board notch or edge
shape so as to offset the board stop position.

Setting procedure
When using the board edge offset, set the value to “v. Board Edge Offset Lower Left” or “w. Board Edge Offset Lower
Right” on the [Print]-[Board] tab screen through teaching using the [Offset Teach] button.
The initial value is "0.0". When the board edge offset function is not used, remain the initial value.
To use the board edge offset function, follow the steps below.
1. Press the [Offset Teach] button on the [Print]-[Board] tab screen.
2. The screen appears, allowing you to select a board edge offset you want to perform the teaching. Select a desired
board edge offset and press the [OK] button.
