Hi, Scott,
Fab Houses quite often put their own serial numbers on boards, so it would
be no big deal for them to put yours on as well as or instead of their own.
Normally, though, it's the assembly you want to serialise, not the board
itself. If a bare board is scrapped prior to assembly, you are left with an
unnecessary gap in the serialisation of the assembly, so I've never had
assembly serial numbers put onto bare boards at fabrication stage.
I have always serialised boards at the start of assembly by stamping or
hand marking with epoxy ink in a pre-designated space. Once all the messy
processes are over that would damage them, labels are finally fitted that
give all the necessary module identification details.

Is anyone currently serializing PCB's, pre or post assembly? What methods
are currently available? I am familiar with pad printing, ink-jet, laser,
labels, etc. Are PCB fab vendors usually set up to serialize PCB's?
