Part Marking Populated PC Board

[dingpud]

Gents,

I have populated boards which a white box screen printed onto the board where a part number or serial number can be written in with a magic marker. I am looking for something more permanent for configuration control reasons and wanted to know if anyone has any successful experience with this. Since Sharpie's can be alcoholed off, we'd like to engrave something, but don't want to damage the integrity of the board.

Any and all suggestions are appreciated.

Thanks,

You could use very sticky and durable labels. We use those for some of our board markings. It either needs to be in metal, silk, or stuck on with those foil labels. I agree that Sharpie won't be great in the long run.

Are you printing or designing the PCB yourself? You could always print the number in copper on the conductor side.
