you posted words
???
a question may be responded to with words, as you have done
but your words are without meaning
it seems clearly you lack the info even needed to answer intelligently
perhaps you DO know the answers, lets try . . . .
who says that s17 kiows all about lapping ? (you ?, ok, what do you know ? about s17 ? and about lapping ?)
do you do lapping for a living ? who does lapping for a living ? are all lappers equally qualified ?
testing ? what kind of testing ? to what criteria ?
you should look up QA and QC, the answere are there
if this was a test, you failed
