Function: Used for testing the basic functions, connection between software and hardware is the
mainly function, details about testing as below, see the Figure 4.17.
4.5.1 Placement head
Figure 4.18
Choose nozzle 1, nozzle 2, nozzle 3, nozzle 4 to test separately, see the Figure 4.18.
(1) The “Blow” button will release a brief jet of air from the selected nozzle. Place a finger under
the nozzle to verify operation. A small increase in positive value should appear on the screen.
(2) The “Suck” button will engage vacuum for the selected nozzle. Place a finger over the nozzle to
block airflow, and press the button. If the unit is operating correctly, you will feel the vacuum, and
the “pressure” indicator will change from a positive to a significant negative value while vacuum is
present.
(3) The “Turn left” and “Turn right” buttons activate the rotational axis of the selected nozzle.
Because rotation of the smooth black nozzles is difficult to observe, it is easiest to verify function
by watching the motion of the vacuum tubes at the top of the head.
(4) Down, after click this option, selected nozzle will descend slowly. Releasing the button causes
the nozzle to return to its upper position.
(5) The “Flash” button activates the lighting for the downward-looking •camera. Press once for the
inner lights, again for the outer lights, again for both, and a fourth press will turn the lights off.
(6) The “Photograph” button verifies operation of the downward- looking camera by moving the
head back and displaying a photograph of the table.

(7) Vacuum value 1, 2, 3, 4, Based on the testing of nozzles, you can see pressure value of each
nozzle.
The “Move Head” button allows repositioning of the head in three ways.
By using the “Visual field” method, the head can be moved precisely by clicking on the portion of
the screen relative to the center crosshairs, which indicate the current position of the camera.
Because of the extreme closeup vision of the camera, only small moves are possible with each click.
With the “Mouse Vectors” setting, the screen turns grey, and represents the entire area of movement
possible over the table. Clicking in any region of the screen allows rapid, coarse movement of the
head. This can be convenient for speeding alignment, as well as for moving the head to a more
convenient general location for the task being performed.
The “Keyboard Jog” method allows movement in of the head along the X and Y axes in .1 mm
increments. Additional keyboard controls are noted on the screen. To exit this mode, press the
Escape key.
Z Axis: When in an alignment screen, the default “camera” setting allows the visual check of X and
Y coordinates. But the selection of one of the nozzles as an alignment method allows the manual
extension of the nozzle along its 12 mm Z-axis travel. This feature is useful not only to verify
operation of the Z-axis motor, but to determine the best values for “pick height” and “place height”
in the feeder settings of a P&P program.

Function, test rail PCB feeding, forward PCB feeding, backward PCB feeding and feeding speed,
see the Figure 4.19.

4.5.3 Host control
Figure 4.20
In the “Host Control” section, seven controls complete the manual test interface. See the Figure 4.20.
Start button status, on the left side of machine, it has one start button, press this button the status will
change
The “Flash” button activates the lighting system for the upward- looking camera. A second press
turns off the lights.
The
“Image”
button verifies operation of the upward-looking camera by displaying an image on
the screen. Because the camera focus is set to take very sharp pictures of the nozzles and any
components they are carrying, pressing this button may produce only a blurry image unless an
object (like the head) is present over the camera at the correct height. Pressing “Cancel” returns the
user to the main screen. (The Lens Rotation and Save buttons are used for nozzle alignment
purposes, and perform no valuable function in the Manual Test context).
The
“Feed Command”
activates the rail system for those units so equipped.
The “Buzzer” button sounds the internal warning tone for as long as it is pressed.
The “Clear X Y” button should only be used to correct an error condition displayed in the “XX
Status” annunciator position. When the status reads “Idle,” the system is functioning normally and
there is no need to use this button.
The
“Home”
button causes the X and Y drives to return the head to the machine’s home position,
and reset the X-Y geometry based on the physical limit switches in the unit. Use this button to
verify operation of the limit switches, and also to restore the home position in the event of an
accidental head crash into an object inadvertently left on the table.
The
“Vibration feeder”
check-box will activate the vibration feeder motor when checked.
Leave the box unchecked except for this brief test.
