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?
