Ken:

What does this faction say about rows of radially mounted parts where the
part identification is hidden by the adjacent part?  Do they request new
board designs? What about identification of axial parts formed on automatic
equipment? The numbers will not always be facing up. So then, do you hand
form every part so that the marking faces up? I wouldn't think so.

Here, the operator records traceability data as a board is stuffed (class
3). If normal processing removes the part marking, then the traceability
data along with the test data validates that the correct part was installed.

It makes no sense to remove any part once it is soldered unless test data
indicates problems.
