What to do if the GR&R fails?
●
Measure again: fiber, dust could have fallen on the pad during GR&R test.
●
Is the machine cover opened? Is the board properly clamped?
●
Is the board bouncing because it´s thin, not properly supported?
●
Is the paste on the board slumping? Check for hardware issues.
●
Was there any disturbance to the CR&R process to the target?
