Press the emergency stop button and attach the glass QFP to Head 1.

Attach the glass QFP to the nozzle of Head 1, with the pin-pattern-printed surface

facing down (toward the camera), and then press the [OK] button.

NOTE

Handle the glass QFP carefully and protect it from dust and grime. Dust, grime or nicks on the glass QFP surface

may cause recognition errors or result in poor adjustment.

Make sure the nozzle picks up the center of the glass QFP.

1. Camera parameter adjustments

Cancel emergency stop and press the [Execute] button to start

calibration.

The head assembly moves to a position above the single-vision camera and the

camera scale is automatically calibrated.

Check the calibrated results.

When the scale calibration is complete, a dialog box appears asking whether to save

the results. Check that the results are within the typical range (shown in table below)

and press the [Yes] button to enable the results.

Remove the glass QFP from the nozzle.

When the dialog box appears after saving the data, press the emergency stop button

and remove the glass QFP by hand from the nozzle. Then press the [OK] button in the

dialog box.

CAUTION

If you press the [OK] button while the glass QFP is still being held by to the nozzle, the glass

QFP will be automatically dumped and possibly damaged. Always first remove the glass QFP by

hand and then press the [OK] button.

2. R-axis accuracy offset

R-axis accuracy offset is the angular offset of the R-axis that rotates each nozzle shaft to

mount a component. This section explains how to measure R-axis accuracy offset with

the multi-vision camera and single-vision camera (option). The same glass QFP as for

camera scale calibration is used.

When measuring the R-axis accuracy offset of Heads 3, 5 and 7 (YV100Xg family), an

error occurs unless head offset adjustments have been performed on those heads. So,

before measuring the R-axis offset, perform head offset adjustments on Heads 3, 5 and 7

by referring to sections 3.1 and 3.2 in this chapter. In addition, when using SOP compo-

nents to measure the R-axis offset of Heads 2, 4, 6 and 8, also first perform head offset

adjustments on those heads by referring to sections 3.3 and 3.4 in this chapter.

CAUTION

Head offset adjustments performed before measuring the R-axis accuracy offset are temporary

settings. Be sure to perform head offset adjustments on all heads after the R-axis accuracy

offset measurements are complete.

NOTE

When measuring the R-axis accuracy offset of Heads 3, 5 and 7, a glass QFP is used so the "Adjust Mode" must

be set to "Adjust Mode2" (see sections 2.5 and 2.6 in Chapter 2). When measuring the R-axis accuracy offset of

Heads 2, 4, 6 and 8, SOP components are used so the "Adjust Mode" must be set to "None". In both cases, the

PCB data called "MCH_SETUP" must be loaded into the machine (see section 2.7 in Chapter 2). You can check

the currently selected PCB data and "Adjust Mode" displayed on the status bar.

For how to start the adjustment utility, see section 2.4 in Chapter 2.

Press the [Multi Camera] button in the adjustment utility menu

window.

The multi-vision camera adjustment dialog box appears.
