Calibration Procedure for Fine-Pitch
Placer portion of BGA-3000
INTRODUCTION:
The Fine-Pitch Placer portion of the BGA-3000 Rework System is a precision optical instrument that will
provide its user with the ability to accomplish precise, repeatable alignment of component leads or balls
with the mating land pattern on the PCB board. Accurate alignment and placement of any component are
dependent on the system’s optics being adjusted properly. The unit is calibrated at the factory, however;
calibration may be required due to shipping or rough handling. It is advised that the unit’s calibration be
checked prior to use to avoid any placement errors.
CALIBRATION VERIFICATION:
NOTE: Please read user’s manual prior to performing any calibration to insure familiarity with unit.
MATERIAL REQUIRED:
1.
Gun Sight Alignment assembly PN: 20066 (provided with system)
2.
Vacuum Cup size 0.4 PN: 19790 (provided with system)
CAMERA SETUP
1.
The camera has been pre-set at the factory to the following:
a.
“C” mount adapter has been locked with “C” mount fixing screws to 1 1/2
turns from fully home.
b.
Shutter speed has been set: NTSC/PAL
c.
White balance set to auto.
Note: Please do not change these settings
1 1/2 turns from fully
home.
SYSTEM SETUP:
1.
Assemble the unit as described in the user’s manual.
2.
Turn power on to the unit (refer to users manual if necessary).
3.
With the vacuum head assembly at the top position install the vacuum cup
size 0.4 PN: 19790 (Refer to DWG # 5 in Factory Calibration Procedure).
4.
Place the Gun Sight Alignment assembly PN: 20066 onto the board holder and position the center
of the gun sight pattern under the vacuum pickup head. (Lower the head until the vacuum cup
almost touches the gun sight alignment plate.) See FIG A and text below FIG A. If the removable
gun sight plate is still on the assembly remove it now. Set it aside and proceed to position pattern,
still on alignment assembly, in center of cup. After gun sight is aligned with vacuum cup move
head back to top position.
5.
Turn the “Z” adjustment knob fully counterclockwise and then 1/2 turn back clockwise.
