Hi everyone,
Can somebody help me to understand this ?
One of my customer needs like this, QC requirement: cpk=1.33 min on critical characteristics, vendor need to perform 0.05% AQL Inspection. (DPPM=500)
Non critical characteristics shall be measured in accordance to this drg to an AQL of 0.65% (DPPM=6500)
My question is, When using SPC, At what frequency i have to take my SPC study( i mean the quantity) or How would i interpret & prove to the customer about my inspection methods?
Hope to get an answer soon.
Thanks & Regards
Arockia.
