Well you certainly have made a god effort at crossing all your "T"s and dotting your "I"s.
First of all, I don't think there are "standard" notes for fabrications or assemblies since no two companies have exactly the same needs or products. In our case I created "General requirement" documents for the Fab and the PCBA levels and referenced these documents on the Fabrication/assembly drawings. This way I can add or change a requirement (like when the shift to the J-STD-609 happened) without having to re-issues all my drawings for all our assemblies. A simple "...mark per J-STD-609..." type statement should suffice if you have no other concerns.
We use the J-609 pretty much as written, but this is for our benefit as well as compliance. We have some leaded products that are still exempt and old product inventory that we sell to non-lead regulated countries. So we want our own people to know what they have in hand during each step of production and the standard is helpful for this.
If your CM (or in house production manager) is giving you grief for the miniscule labor of marking the boards, you may want to consider adding the marking to the silk-screen or top copper layer of the board. Eliminates the labor and satisfies RoHS (to the best of my knowledge).

Subject: [DC] RoHS compliant, Pb-free, J-STD-609 markings on PCB and PCBA
I'm researching how to (or whether I even have to) get to this level of detail on marking PCBs and PCBAs intended to be RoHS compliant.
For the sake of discussion, let's say:
(1) I've verified that all components on the BOM are verified to be Pb-free.
(2) I've specified on the PCB drawing some manner of Pb-free surface finish on an IPC-4101/24 Tg 170 oC minimum FR-4.
(3) I've specified on the PCBA drawing that I want a RoHS compliant finished assembly.
(4) I've specified IPC-6012 Class 2.
Given that the RoHS Directive 2002/95/EC of the European Parliament does not require any markings except at the component level, but simply stating "RoHS compliant" may not be enough,
(5) How many of you are required by your companies to mark the bare PCB and the assembled PCBA with J-STD-609 markings, and
(6) What do your standard J-STD-609 PCB and PCBA drawing notes look like, since there seem to be no such standard notes published yet
(7) Or, if I am mistaken, can anyone kindly direct me to a location for published standard notes?
Give me a solution that doesn't add cost to the assembly, but at the same time satisfies those who are bothered by Pb, please.
TIA and Best Regards,
