Checking of placement result
Cause Troubleshooting
The target components are deteriorated
Check for any flaws or foreign bodies on the
surface of JIG_BGA.
The correct jig parts are not used. Check the jig parts.
Actual parts 1005C are used. Check the jig parts.
The head shaft is damaged Check for unsmooth sliding of the shaft.
The illumination of the multi-recognition
camera is wrong.
Execute the lamp-value illumination calibration.
Calibration
●If you perform above measures, but the accuracy verification result is not improved or you find any trouble
on the head shaft, please contact us.
Verifies the results registered as offsets in “Checking and reflection of placement.” The procedure is the
same as the one used in “Checking and reflection of placement.”
Though not necessarily required, this procedure will be used as a guideline for measuring the level of
accuracy of the machine.
●As for MCDATA (production program), use accuracy verification MCDATA.
(→ P.13-21-1
-1 ’■MCDATA type’)
●Accuracy verification MCDATA is intended for accuracy verification use, so refrain from reflecting in it the
each-position-angle offsets obtained from measurement results.
(→ P.13-21-1
-1 ‘■Reflection of verification data’)
The following causes are cited as possible causes when no improvements are seen in accuracy verification
results.
