I have seen some previous discussions on this topic (2008) and wondered if there had been any updates. I work for a large assembler. I deal with several opinions on APQP paperwork from all over our company. I have a question I would appreciate your feedback on:
Inspection steps (End of line inspectors, continuity, vision). Do they belong on the PFMEA? I have always added them as a process step but not assigned failure modes. I have always been trained they belong as detections only. FOR EXAMPLE: The failure mode suggested by my team is: "Vision passes bad part" (as well as "vision fails good part"). Well, dont we assume everything coming into the station is good? Would failures here not be captured on a MFMEA? Also, what are my detections? 5x5? Red Rabbit? And...if you deal in a General Motors world, this creates extra RPL1/S situations in which deviations would be needed for critical characteristics. And, .....If you were to add add vision failures to a PFMEA (which checks for many things), do you break each vision "inspection" down to severities? This could get VERY cumbersome and not really value added. I could understand adding items like damaged part (if the EOL operator lifts the part up)...
