4.7 GR&R Test
After completing the calibrations, perform a GR&R to check that the Process Lens PL is ready for
measurements.
What is GR&R?
Performing the GR&R procedure on a pasted or a simulated pasted board such as the CeTaq glass
target allows us to check that the Process Lens PL is:
1. measuring precisely with little variation.
2. of many dimensionally diverse targets.
3. when measured repeatedly.
What value does the Process Lens PL need to achieve?
The %GR&R of the Volume(%), Area(%), Height(mm), Offset X and Offset Y(mm) reported at the end
of the procedure should be less than 10%, a value which indicate that the variations in the measure-
ments attributed to the Process Lens PL is much smaller that the variations of all the parts measured.
A %GR&R of greater than 10% is an indication that there is an issue in achieving precision and the
root cause of measurement variation needs to be corrected.
What is needed?
●
Use a CeTaq glass board (with simulated paste deposits).
●
A working recipe of the board without bad marks.
Pre-condition before GRR test is carried out.
Recipe of CeTaq glass board is created including.
1. Fiducal teached and verified.
2. Bare Board Teach is teached and verified.
