Re: Open up HP12cp? Message #5 Posted by bill platt on 31 July 2009, 12:15 p.m., in response to message #3 by Mike (Florida)
Well, to be fair, HP is no longer producing these in Corvallis, and the unit price is about what, say 33% of what it was when originally issued, in real dollars?
That is not to say that there shouldn't be QC. But it isn't the same thing is it?
Really, with these sorts of very low-cost technical devices, there isn't enough money to do "QC" the old way. Rather it has to be SPC/SQC of the manufacturing system. This means that some finite number of flawed devices will come through the line ,undetected--and that you them minimize the total cost by accepting some finite number of warranty trades for less expensive processing....and by statistically tracking the warranty issues, you then improve the process to reduce the statistically significant flaws.
Lots of gobbledygook but the fact is that any significant handwork is out of the question....
