we all have different quality requirements and reasons for what we do. maybe its the board vendors we choose to work with, but i do not like just giving them cart blanc. i guess i've had enough bruises from manufacturing when a quality issues arises that's board vendor related (the further a quality issue gets thru a manufacturing process, the more expensive it is to correct). 'inspecting the heck' out of a vendor doesn't seem to be the way we would like to go. but, then again, it comes down to choices. i do appreciate and thank you for the feedback. -----Original Message----- From: John Brewer [mailto:[log in to unmask]] Sent: Friday, June 02, 2000 11:10 AM To: [log in to unmask] Subject: [TN] PE: PCB Inspection Ed Noble writes: ".. consider, at least, changing to a SAMPLING PLAN in your evolution to addressing board quality. that way, you can still 'keep an eye on' the copper plating concern. from 'inspecting' to 'dock to stock' is quite the change." Hi Ed! I'd tend to disagree. Consider that, while you have the opportunity to do a full Incoming/first article, you're getting the most complete and detailed information and feedback in the form of data, to make your dock to stock decision on. Going to sampling/skip lot as an interim state seems to be more of a period of weaning, rather than a statistically valid step. I think it's a "warm and fuzzy feeling" period. If you're concerned about a vendor, inspect the heck out of their stuff, and get the issues worked. Once they are, and they demonstrated their ability to sustain their process, make the jump to ship to stock while you still have the BES, and most complete data you have regarding their incoming quality.
