16-1 Creating programs and data
Two types of optional dispense heads are available: a high-end dispense head, and a standard dispense
head.
The high-end dispense head features a screw pump format to discharge the dispense material, and it is
therefore called a screw type dispense head.
The standard dispense head features an air pressure format to discharge the dispense material, and it is
therefore called a pneumatic type dispense head.
The following describes data creation and operation steps when the screw and pneumatic type dispense
heads are installed.
Note: This screw type dispense head can be installed only on the “high-precision type 4-axis head”. There are
no restrictions regarding the installing of pneumatic type dispense heads.
Note: The screw type dispense head installation priority is head No. 4→3→2.
For example, when installing one screw type dispense head, install it on the head No. 4. Accordingly,
when installing two screw type dispense heads, install them on the head Nos. 4 and 3.
16-1-1 Data creation
The following describes how to create placement & mark (program), dispense data, syringe data, and
dispense nozzle data.
16-1-1-1 Placement & mark (program)
Menu： Placement & Mark (program)
Action:
① Create a fiducial mark process step at the top of the placement & mark (program).
② Create a laser PCB warpage measurement step next to the fiducial mark process step.
Note: When using the dispense head, be sure to perform the laser PCB warpage measurement before
dispensing. If the laser PCB warpage measurement is not performed, the nozzle pushes the PCB, causing
the nozzle to break.
① Create a fiducial
mark process step.
② Create a laser PCB
warpage measurement step.
③ Create a dot
station step.
④ Create a PCB
dispensing step.
⑤ Create a component
placement step.

Note: The creation of this [Action] ② Laser PCB warpage measurement step is not required when [PCB data: 2]
> [PCB Warp Check by Laser] > [Check Method] > [Dispensing] > [Auto Check] (explained later in this
manual) is selected.
③ Next, create a dot station step.
In this step, the test dispense is performed on the paper sheet on the dot station and this is captured
by the teach camera to automatically adjust the dispense diameter to the set diameter (dispense
area).
In [Code], select [Dispense code] that is created with the dispense data described later. In the [X], [Y],
[Z], and [θ] cells, leave the value “0”.
In [Head], select a head, on which the dispense head is installed. Select “Dot station” in [Task].
Note: When [Eject time after a pause] and [Eject dot count after a pause] of the syringe data described later are
set, the pre-dispense can be performed on the dot station after paused for several seconds and the
pre-dispense onto the PCB is not needed.
④ Next, create a PCB dispense step.
In [Code], select [Dispense code] that is created with the dispense data described later.
In [X] and [Y], enter coordinates of the dispense point on the PCB.
In [Head], select a head, on which the dispense head is installed. Select “Dispense” in [Task].
Note: Multiple dispense point offsets from [X] and [Y] of the above reference dispense point on the PCB can be
set with the dispense data described later.
⑤ Next, create a component placement step when necessary.
Note, however, that component placement is not possible with the D10 dispenser.
