Checking of Placement Results (Same as Reflection of Placement
Results)
This process is not always necessary; however, the machine’s real accuracy can be measured.
If the accuracy verification result is not improved in spite of a repetition of reflection, this may be
arisen from the following causes.
Cause Troubleshooting
The target components are deteriorated. Check for any flaws or foreign bodies on the
surface of JIG_BGA.
The correct jig chips are not used. Check the jig chips.
Actual components 1005C are used. Check the jig chips.
The head shaft is damaged. Check for unsmooth sliding of the shaft.
The illumination of the line camera is
wrong.
Execute the lamp-value illumination calibration.
